Technical characteristics and installation methods of permanent magnet stepper motors
1.Basic introduction to permanent magnet stepper motors
Permanent magnet stepper motors are motors that use the interaction between permanent magnets and electromagnetic coils to generate rotating power. Its basic working principle is to apply currents of different phases in the stator windings to generate a rotating magnetic field, which interacts with the permanent magnets on the rotor to make the rotor rotate step by step.
2.Technical characteristics of permanent magnet stepper motors
1.High precision and high reliability: The torque and position control accuracy of permanent magnet stepper motors are very high, and high-precision position positioning and motion control can be achieved. Because its mechanical structure and control circuit are relatively simple, there are no vulnerable parts such as brushes and commutation mechanisms, so it has high reliability and stability, and can operate stably for a long time.
2.Noise-free and pollution-free: Permanent magnet stepper motors have no mechanical contact parts, so they will not generate noise, nor will they generate pollutants caused by friction and wear, and are suitable for applications with high environmental requirements.
3.Controllable speed and acceleration: The speed and acceleration of permanent magnet stepper motors can be precisely controlled by the controller, and have broad application prospects.
4.Large step angle: The step angle of permanent magnet stepper motor is large, the starting and running frequency is low, and positive and negative pulse power supply is usually required.
5.There is positioning torque when power is off: Because the rotor is a permanent magnet, the permanent magnet stepper motor can still maintain positioning torque when power is off, and the power consumption is small.
6.Good dynamic performance: The permanent magnet stepper motor has good dynamic performance, but the step angle is large.
3.Installation method of permanent magnet stepper motor
1.Preparation: Before installing the stepper motor, ensure that the decoration and other construction of the application environment site and the preliminary installation of the equipment have been completed to avoid contamination or collision of the motor during installation, resulting in damage or failure.
2.Strictly follow the instructions: When installing the stepper motor, you must strictly follow the requirements in the instructions, including the installation method and steps, to ensure that each step meets the requirements to ensure the working state and use effect of the motor.
3.Connect the motor and the driver: Connect the stepper motor to the stepper motor driver. Usually, the positive poles of the pulse input signal and direction input signal of the stepper motor driver need to be connected to the 5V terminal of the controller, the negative pole of the pulse input signal needs to be connected to the Y1 output terminal of the controller, and the negative pole of the direction input signal needs to be connected to the Y2 output terminal of the controller.
4.Set the driver parameters: Set the subdivision of the stepper motor driver, which can generally be set to around 8 (1600). Set the actual subdivision after preliminary debugging. At the same time, set the action of the stepper motor, including the forward and reverse settings.
5.Debugging and testing: After completing the installation and setting, debug and test to ensure that the motor can work normally and the forward and reverse functions are normal.
4.Methods to increase the life of permanent magnet stepper motors
1.Correct selection: It is crucial to select a stepper motor suitable for the application scenario. It is necessary to comprehensively consider factors such as load characteristics, movement speed, and accuracy requirements. If the load is too heavy, the motor will be in an overloaded state for a long time, which will cause the motor to overheat and shorten its service life. On the contrary, if the motor is too large, it will not only increase the cost, but also may lead to a decrease in control accuracy.
2.High-quality drive controller: A high-quality drive controller can accurately control the phase current of the motor to achieve smooth movement and precise positioning. The use of subdivision drive technology can effectively improve the running smoothness and accuracy of the motor, reduce vibration and noise, reduce heat, and extend the service life of the motor.
3.Reasonable drive and control: Reasonably set the acceleration and deceleration time of the motor to avoid excessive acceleration and deceleration, which will cause the motor to generate excessive impact current, affecting the life of the motor and drive controller. At the same time, control the working temperature of the motor to avoid working in a high temperature environment for a long time. The working temperature of the motor can be reduced by installing a radiator and optimizing ventilation conditions.
4.Good installation and wiring: The correct installation method can ensure the normal operation of the motor and reduce mechanical wear. When installing the motor, ensure the concentricity of the motor shaft and the load shaft to avoid eccentricity. At the same time, choose a suitable installation and fixing method to ensure the stability of the motor.
5.Regular maintenance and inspection: Regularly check the insulation performance, bearing lubrication, etc. of the motor, and handle faults in time. Keep the motor clean to prevent poor heat dissipation and corrosion. Avoid operating the motor in harsh environments, such as high temperature, humidity, corrosion, etc., which will shorten the life of the motor.
6.Use high-quality materials: Choose to use high-quality materials to manufacture motors, including high-performance insulation materials and wear-resistant bearings, gears, etc. Improve the processing accuracy of motor components, reduce wear and vibration, and extend service life.
