Improving the performance of stepper motors advantages and implementation of subdivision technology

    A stepper motor is a type of motor that converts electrical pulse signals into angular or linear displacement, with advantages such as high accuracy, simple control, and low cost. However, traditional stepper motor control systems typically use full step or half step control methods, resulting in significant vibration and noise during motor operation, which limits their application in high-precision situations. In order to improve the performance of stepper motors, subdivision technology has emerged.

    The basic principles of subdivision technology
 

    Subdivision technology is a method of improving the smoothness and positioning accuracy of motor operation by changing the way the motor winding is energized to generate more stepping angles during operation. The basic principle of subdivision technology is to divide the winding current into multiple stages within a step angle, with each stage corresponding to a subdivision step angle. By controlling the variation of winding current, the subdivision operation of the motor can be achieved.
 

    The advantages of segmentation technology
 

    Improving operational stability: Subdivision technology enables the motor to generate multiple subdivision step angles within one step angle, reducing vibration and noise during operation and improving operational stability.
    Improving positioning accuracy: Subdivision technology enables the motor to have higher resolution during operation, thereby improving the positioning accuracy of the motor.
    Improving motor efficiency: Subdivision technology reduces motor losses during operation and improves motor efficiency.
    Expanding application scope: Subdivision technology enables stepper motors to have better performance in high-precision, high-speed and other fields, expanding their application scope.
 

    Implementation methods of subdivision technology
 

    Pulse signal subdivision: By increasing the pulse frequency of the control system, the motor generates multiple subdivision step angles within one step angle.
    Driver segmentation: Using a driver with segmentation function to control the motor winding current and achieve segmented operation.
    Motor structure optimization: Optimize the motor structure, such as using high-precision machining, special materials, etc., to improve the implementation effect of subdivision technology.
 

    Subdivision technology is an effective means to improve the performance of stepper motors, which has advantages such as improving operational stability, positioning accuracy, and motor efficiency. In practical applications, appropriate segmentation methods and implementation strategies should be selected based on specific needs, fully leveraging the advantages of segmentation technology. With the continuous development of subdivision technology, the application of stepper motors in various fields will be more extensive, making greater contributions to the improvement of industrial automation level in China.
