‌‌Precautions for using waterproof stepper motors

1.Brief description of waterproof stepper motors

Waterproof stepper motors are stepper motors that can work normally under a certain waterproof level. It effectively prevents water, dust, etc. from entering the motor through special shell design and waterproof shaft seal and other technical means, so as to maintain normal operation in harsh environments. Waterproof stepper motors have the advantages of high efficiency, stability and reliability, and are widely used in home appliances, machinery, automobiles and other industries.

2.Design features of waterproof stepper motors

1.Insulation material: The motor winding adopts polyethylene insulation and nylon household waterproof electromagnetic wire. The cable connection method is based on cable joint technology. The seam insulation is removed from the scraped paint layer, the welding is firm, and the raw rubber is wrapped around the layer to ensure waterproofing.

‌2.Anti-corrosion material: The outer part of the motor is made of anti-corrosion material or anti-corrosion coating, and the sealing mechanism blocks the cracks or channels that may exist inside and outside to ensure that water does not enter the motor and cause short circuit failure. 

3.IP protection level: The motor industry has a standardized liquid protection measure called IP protection level, which power engineering and motor manufacturers need to meet the application specification requirements.

3.Structural composition of waterproof stepper motors

1.Housing: Made of stainless steel, it has good waterproof and dustproof performance and can work normally in harsh environments.

2.Motor drive part: It includes the motor body, circuit board and power supply, providing efficient and stable power output.

3.Bearing: High-strength bearings are used to withstand high loads and high speed requirements.

4.Sealing ring: Made of high-strength materials, it effectively prevents corrosion and moisture from penetrating into the motor.

5.Stator: The stator is the stationary part of the stepper motor, usually composed of multiple poles, which can be permanent magnets or electromagnets. Its main function is to generate a magnetic field and drive the rotor to rotate.

6.Rotor: The rotor is the rotating part of the stepper motor, usually made of magnetic materials, which can be permanent magnets or soft magnetic materials. Its main function is to generate torque under the action of the magnetic field generated by the stator to rotate the motor.

7.Winding: The winding is the conductive part of the stepper motor, usually wound around the magnetic poles of the stator, generating an electromagnetic field to drive the rotor to rotate.

‌8.Controller: The controller is the control part of the stepper motor, responsible for receiving pulse signals and converting them into motor rotation, usually including drive circuits, pulse distributors and microprocessors, etc.

‌9.Encoder: The encoder is the feedback part of the stepper motor, used to detect the rotation position and speed of the motor, usually including photoelectric encoders, magnetic encoders or Hall sensors.

4.Precautions for the use of waterproof stepper motors

1.Control signal line and power supply connection: Make sure that the control signal line is firmly connected, and it is best to consider shielding issues at industrial sites. The power supply voltage should be appropriate, and the +/- polarity of the DC input must not be connected incorrectly. The motor model or current setting value on the drive controller should be appropriate.

‌2.Grounding method: Be sure to understand the grounding method. Using floating without connection may cause the motor to work unstably. Closely observe the status of the motor within half an hour of starting operation, such as whether the movement is normal, the sound and temperature rise, and stop and adjust immediately if any problems are found.

‌3.Use environment‌: Although waterproof stepper motors can be used in dusty, humid or oily places, it does not mean that they can work in water. Try to place them in a relatively clean environment and avoid long-term immersion in water‌.

‌4.Maintenance and care‌: Regularly check the exterior, fixed parts, output shaft, encoder connection cable, power connector, cooling fan, etc. of the stepper motor to ensure that they are firmly connected and operate normally. Clean dust and oil in time to ensure that the motor is in normal condition‌.

‌5.Cable protection‌: Ensure that the cable is not subjected to torque or vertical load due to external bending force or its own weight, especially at the cable outlet or connection. In the case of moving stepper motors, the cable should be firmly fixed to a stationary part, and it should be extended with an additional cable installed in the cable support to reduce bending stress‌.

‌6.Load control‌: Ensure that the radial and axial loads applied to the stepper motor shaft during installation and operation are controlled within the specified values ​​for each model. It is best to use a flexible coupling to reduce load damage or wear on the shaft end and bearings‌.

‌7.Installation precautions‌: When installing/removing the coupling component to the stepper motor shaft end, do not hit the shaft end directly with a hammer to avoid damaging the encoder. Try to align the shaft end to the best state to avoid vibration or bearing damage‌.

Debugging steps and optimization methods of closed-loop stepper motors

1.Brief introduction of closed-loop stepper motors

Closed-loop stepper motors are high-precision servo motors. By installing position sensors such as encoders or resolvers on the motor shaft, the actual position of the motor is fed back to the control system to achieve closed-loop control. This design makes the closed-loop stepper motor have the advantages of high precision, high stability and low vibration, and is suitable for occasions with high precision requirements.

2.Working principle of closed-loop stepper motors

The working principle of closed-loop stepper motors is similar to that of open-loop stepper motors. Both control the rotation angle of the motor by receiving pulse signals. The difference is that closed-loop stepper motors add a position feedback link to the control system. When the motor rotates, the position sensor detects the actual position of the motor and sends this feedback signal back to the control system. The control system adjusts the drive current and phase of the motor by comparing the input signal and the feedback signal, thereby more accurately controlling the position and speed of the motor.

3.Debugging steps of closed-loop stepper motors

1.Initialization parameters: Before wiring, the parameters need to be initialized. This includes selecting the appropriate control mode on the control card, clearing the PID parameters, ensuring that the default enable signal is off when the control card is powered on, and saving this state. Set the control mode, enable external control, encoder signal output gear ratio, and the proportional relationship between the control signal and the motor speed on the stepper motor.

2.Wiring: Power off the control card and connect the stepper motor driver and the stepper motor according to the instructions. Make sure all connections are firm and not loose.

3.Debug the stepper motor driver: Set the subdivision number, start-up speed, single-axis acceleration, and cornering acceleration of the stepper driver as needed. The higher the subdivision number, the higher the control resolution, but it will affect the maximum feed speed. The start-up speed is the highest frequency at which the stepper motor can start working directly without acceleration. Single-axis acceleration and cornering acceleration describe the acceleration and deceleration capabilities of a single feed axis and multiple feed axes when linked, respectively.

4.Use encoder feedback: In a closed-loop control system, use the encoder to feedback the real-time speed of the motor, and adjust the output of the pulse frequency after comparing it with the set value to achieve accurate speed tracking and enhance control accuracy. ‌5. S-type acceleration curve‌: Use S-type acceleration curve for smooth acceleration and deceleration control, so that the speed increases or decreases smoothly according to the set slope, and realizes smooth start and stop‌.

4.Optimization method of closed-loop stepper motor ‌

1. Subdivision control‌: By increasing the number of teeth on the rotor, the accuracy of the stepper motor can be improved. Subdivision control can make the stepper motor move a smaller step size under each pulse, thereby improving positioning accuracy‌.

‌2.Closed-loop control‌: Closed-loop control is a key method to improve the accuracy and stability of stepper motors. By adding position feedback to the motor control system, the closed-loop control system can detect the actual position of the motor in real time during the motor movement and compare it with the target position. If a deviation is found, the system will send instructions for correction to ensure that the motor runs according to the expected path and speed. This method can effectively prevent step loss and vibration and improve the stability and accuracy of the system‌.

3‌.Configure a reducer‌: By configuring a reducer on the stepper motor, the speed of the motor can be reduced and the torque can be increased, thereby improving the stability and accuracy of the system. The function of the reducer is to reduce the rotation speed of the motor and increase the output torque. It is suitable for scenarios that require high torque and low-speed operation.

‌4.Use a cost-effective drive solution: For example, use the TMC4361 stepper closed-loop drive solution, which combines the TMC2130/TMC5130 (low power) or TMC2160/TMC5160 (high power) driver chip, built-in closed-loop algorithm and current control, supports S-shaped ramp acceleration and deceleration, and has the characteristics of high response, high speed and high precision.

‌5.Optimize current control: The performance of the stepper motor can be further improved by optimizing the current control strategy. For example, using an absolute encoder or an incremental encoder can achieve more precise position control.

Speed ​​regulation method and selection conditions of AC gear motor

1.A brief introduction to AC gear motor

AC gear motor is a device that converts high-speed and low-torque motor output into low-speed and high-torque output, and is widely used in industrial production. The components of AC gear motor include AC motor, reducer and output shaft. The AC motor provides power, the reducer reduces the speed through the transmission of gears, and the output shaft connects the mechanical equipment to provide torque. The reducer is usually composed of components such as gears, worm gears, transmission shafts and bearings. Its working principle is to reduce the speed of the input shaft to the output shaft through the transmission of gears, while increasing the output torque of the output shaft.

2.Characteristics of AC gear motor

‌1.High efficiency: AC gear motor adopts an efficient gear transmission system, which can provide efficient mechanical conversion and reduce energy waste.

‌2.Low noise and vibration: Through precision manufacturing and optimized design, AC gear motor can reduce noise and vibration and provide smooth and quiet operation.

‌3.High reliability: Made of high-quality materials and advanced processes, it has good mechanical strength and durability and can operate reliably under various working conditions.

‌4.Precision control‌: Equipped with precision encoders, it provides accurate speed and position feedback, enabling the control system to accurately control motor movement‌.

‌5.Multiple configuration options‌: Provide different voltages, speeds, output powers and axial mounting methods to meet different application requirements‌.

3.Requirements for AC gear motor selection

1.Load characteristics‌ is one of the key factors in selection. The reduction ratio and output torque need to be determined based on the actual load characteristics of the equipment. If the load is large, a gear reduction motor with a larger reduction ratio needs to be selected to increase the output torque; if the load is small, a gear reduction motor with a smaller reduction ratio needs to be selected to improve operating efficiency‌.

2.Output speed‌ is another important factor. The output speed of the motor needs to match the working requirements of the equipment. If the output speed is too high or too low, it will affect the stability and operating efficiency of the equipment. Therefore, when selecting a gear reduction motor, the output speed needs to be determined based on the working requirements and load characteristics of the equipment‌.

3.Motor power‌ is also an important parameter for selection. The rated power of the motor needs to be determined based on the actual power requirements of the equipment. If the motor power is too low, it cannot meet the working requirements of the equipment; if the motor power is too high, it will waste electricity and cause unnecessary costs. Therefore, when selecting a gear reduction motor, it is necessary to determine the rated power of the motor according to the actual power demand of the equipment.

4.Environmental conditions are also a factor that needs to be considered. The protection level and corrosion resistance of the motor need to be determined according to the working environment of the equipment. If the working environment of the equipment is harsh, it is necessary to select a gear reduction motor with a higher protection level and corrosion resistance to ensure the safe operation of the equipment.

4.Speed ​​regulation method of AC gear motor

‌1.Speed ​​regulation by changing the number of motor poles: The speed of the motor is adjusted by changing the number of motor poles. This method is suitable for application scenarios that require a wider speed regulation range.

‌2.Speed ​​regulation by changing the motor slip rate: The speed is adjusted by changing the slip rate of the motor. This method is suitable for wound asynchronous motors, but the speed regulation range is small, and the resistance consumes power and the efficiency is low.

‌3.Speed ​​regulation by changing the power supply frequency of the motor: The speed is adjusted by changing the power supply frequency of the motor. This method is suitable for occasions that require higher speed regulation accuracy and dynamic performance.

‌4.Serial speed regulation: The speed is adjusted by introducing additional electromotive force in the rotor circuit. It is suitable for wound asynchronous motors and can improve the speed regulation efficiency.

5.Speed ​​regulation of wound motor rotor series resistance: The speed is adjusted by inserting resistance in series in the rotor circuit. This method has a small speed regulation range, but a simple structure and is suitable for some specific equipment such as cranes.

‌6.Stator voltage regulation speed regulation: The speed is adjusted by changing the power supply voltage of the motor. This method is suitable for single-phase motors and some special applications.

‌7.Electromagnetic speed regulation: The speed is adjusted steplessly and smoothly by changing the current of the excitation coil. It is suitable for slip motors, but the control power is small and not suitable for long-term low-speed operation.

‌8.Hydraulic coupling speed regulation: The output speed of the motor is adjusted by the hydraulic coupling. This method is suitable for occasions that require smooth speed regulation.

Reasons for overheating of hybrid stepper motors

1.What is a hybrid stepper motor

A hybrid stepper motor is a motor that combines the advantages of a permanent magnet stepper motor and a reactive stepper motor. ‌ It achieves the complementary advantages of high torque and high precision through a specific structural design, thus providing a high-precision, combined stepper drive. Hybrid stepper motors are divided into two-phase, three-phase and five-phase, of which the two-phase step angle is generally 1.8 degrees, the three-phase step angle is generally 1.2 degrees, and the five-phase step angle is generally 0.72 degrees. The rotor of this motor itself is magnetic, so the torque generated under the same stator current is greater than that of a reactive stepper motor, and its step angle is usually smaller. This makes hybrid stepper motors widely used in occasions that require high-precision control, such as economical CNC machine tools.

2.Design ideas for hybrid stepper motors

‌1.Structural design‌: The structural design of the hybrid stepper motor combines the advantages of variable reluctance (VR) stepper motors and permanent magnet (PM) stepper motors. Specifically, it adopts the gear-shaped iron core rotor of the VR motor, which can achieve a smaller step angle, and combines the strong permanent magnet of the PM motor to enhance the torque output, achieving the coexistence of miniaturization and high torque. This structural layout optimizes the magnetic field distribution and torque characteristics of the motor, allowing the hybrid stepper motor to provide stronger power output without sacrificing step accuracy.

‌2.Number of phases and step angles‌: Hybrid stepper motors are divided into two-phase, three-phase and five-phase, of which the two-phase step angle is generally 1.8 degrees, the three-phase step angle is generally 1.2 degrees, and the five-phase step angle is 0.72 degrees. This design enables the hybrid stepper motor to have a higher step angle resolution and can achieve higher positioning accuracy.

3.Operating conditions of hybrid stepper motors

1.Power supply‌: The hybrid stepper motor needs to be connected to an appropriate power supply to provide the necessary power to drive the motor. The voltage and current of the power supply should meet the specifications of the motor to ensure the normal operation of the motor.

‌2.Control signal‌: The operation of the hybrid stepper motor also requires external control signals. These signals are usually generated by a microcontroller or a special stepper motor driver, which controls the number of steps and direction of the motor by changing the direction and size of the current in the coil.

3‌.Drive circuit‌: In order to convert the control signal into a drive signal that the motor can understand, a special drive circuit is required. These circuits can change the direction of the current in the coil in a timely manner according to the instructions of the control signal, thereby guiding the motor to rotate according to the preset mode.

4.Reasons for the high temperature of the hybrid stepper motor

1.Excessive current‌: When the stepper motor is working, if the current setting is too large, it will cause too much heat energy to be generated inside the motor, thereby increasing the temperature. Excessive current may be because the current set by the driver is larger than the rated current of the motor, or because the speed of the stepper motor is too fast, causing the motor to heat up. ‌ 

2‌.Improper drive method‌: The stepper motor needs to be controlled by the driver. If the driver is improperly set, such as excessive current, unreasonable subdivision settings, etc., it will cause the motor to heat up. Improper driving mode will cause the motor to generate additional heat during operation.

‌3.Long-term operation: If the stepper motor works continuously for too long without proper heat dissipation measures, the heat cannot be dissipated in time, which will cause the temperature to rise. Long-term operation at high voltage or high frequency will also increase the temperature.

‌4.Magnetic material loss: The magnetic material in the stepper motor will generate additional heat due to hysteresis loss and eddy current loss during operation. These losses are inevitable, but can be reduced by optimizing the design and material selection.

‌5.High ambient temperature and poor heat dissipation conditions: The temperature of the operating environment is relatively high, the heat dissipation conditions are relatively poor, or the installation contact area does not meet the standards, which will also cause the stepper motor temperature to rise.

‌6.The working state does not meet the technical requirements: If the three-phase six-beat motor is changed to double three-beat operation, the temperature rise will become higher. This shows that improper adjustment of the working state will increase the temperature rise of the motor.

7.Drive circuit failure: The stepper motor drive circuit fails, and the motor works at a single high voltage or a high frequency for a long time, which also causes the temperature to rise.

5.Stator voltage regulation speed regulation: The motor speed is adjusted by changing the stator voltage. The circuit is simple, the device is small, and it is easy to use and maintain, but the speed regulation range is small and the power is low.

6.Electromagnetic slip clutch speed regulation: The motor speed is adjusted by the electromagnetic slip clutch. The structure is simple, the control device capacity is small, the operation is reliable, the maintenance is easy, and there is no harmonic interference, but the speed loss is large and the power is low.

7.Rotor series resistance speed regulation: The motor speed is adjusted by inserting resistors of different resistance values ​​in series in the rotor circuit. There is no harmonic interference and the technical requirements are low, but the maintenance requirements are high. Only step-by-step speed regulation can be performed, and serious heat is generated during speed regulation.

Material requirements and specific classification of stepper motor encoders

1.What is a stepper motor encoder

A stepper motor encoder is a device used to test speed and positioning, usually installed on the rear end shaft of a stepper motor. Its main function is to be used with a stepper motor. As a feedback system, it detects the angular displacement or linear displacement of the stepper motor and converts it into electrical signals, and then feeds these signals back to the control system, such as a digital control group computer, a programmable controller, etc. By processing the electrical signals, the control system can achieve precise control of the stepper motor.

2.Functions of stepper motor encoders

1.Measuring position

The most basic function of a stepper motor encoder is to measure the position of the motor. As a limited displacement motor, the position of the stepper motor is determined by each step of the stepper motor. The encoder can accurately calculate the current position of the motor. The principle of the encoder is to measure the rotation angle of the motor by processing the photoelectron signal, thereby calculating the position of the motor.

2.Measuring speed

In addition to measuring position, stepper motor encoders can also be used to measure the speed of the motor. The encoder calculates the speed of the motor by calculating the position change of the motor at each moment. For applications such as high-precision positioning, motion control, and adaptive control, the speed information of the motor is particularly needed to help the system adjust the control parameters in real time. By measuring the current speed, the next position can be accurately predicted, thereby improving the motion accuracy and positioning accuracy.

3.Improve motion control accuracy

The encoder can improve the accuracy and stability of stepper motor motion control. By providing a deterministic feedback signal, the encoder can ensure accurate position control and eliminate errors caused by load changes or environmental factors in the motor. In addition, the encoder can also improve the motor's motion performance and reduce noise and vibration by providing more accurate speed feedback information.

3.Material requirements for stepper motors

It uses the interaction between the magnetic strips on the magnetic scale and the magnetic sensor to achieve angle and position measurement. Magnetic encoders are suitable for stepper servo motor systems that have certain requirements for accuracy and stability. ‌

3.Grating scale encoders are high-precision encoders, which are usually used in stepper servo motor systems with high accuracy requirements. ‌It uses the interaction between the grating texture on the grating scale and the photoelectric sensor to provide very accurate position measurement. ‌

4.The magnetic scale encoder is a high-precision encoder based on magnetic technology. It uses the interaction between the magnetic texture on the magnetic scale and the magnetic sensor to provide high-precision position measurement. The magnetic scale encoder is particularly suitable for stepper servo motor systems that require extremely high accuracy and stability. ‌

5.How to install the stepper motor encoder 

1.Select the appropriate location: First, you need to select an appropriate installation location. Usually, the encoder is installed on the motor shaft to achieve real-time monitoring of the motor's rotational position. When selecting a location, you need to ensure that there is enough space between the encoder and the motor and that it can be installed securely. ‌

2.Adjust the installation angle: During installation, you need to ensure that the relative angle between the encoder and the motor shaft is correct. This step usually requires the use of professional tools to ensure that the angle between the encoder shaft and the motor shaft is optimal. The correct angle is critical for accurate position feedback. ‌

3.Connect the cable: Once the encoder is correctly installed on the motor, you need to connect the cable correctly. Make sure that the cable is securely connected and not damaged by external objects. ‌ Use professional cable clamps to avoid unnecessary downtime caused by cable failure. ‌

4.Testing and calibration: After installation, testing is a critical step. Start the motor and monitor the signal output by the encoder to ensure that it accurately reflects the motion state of the motor. Depending on the specific installation location and requirements, some calibration work may be required to ensure that the encoder provides accurate feedback. ‌

5.Regular maintenance and inspection: After the motor encoder is installed, regular maintenance and inspection are key to ensure long-term stable operation of the system. Regularly check whether the connection is firm, whether the cable is damaged, and whether the encoder is working properly.
