1. Products Overview

Step motor is a motor that converts the digital pulse signal into a rotation angle. Its movement is discrete and is carried out in the unit of step length. Therefore, it has high positioning accuracy and repetitive accuracy. The step motor consists of a rotor, a stator, or an encoder for closed-loop stepper motor. The role of the encoder is to detect the rotation position and help control the motor.

When driving the motor, the controller convert the target movement into pulses and then send these pulse signals to a stepper motor driver. The stepper motor driver identify the signals and cover these signals into motor driving pulses. These pulse signals are associated with the angle of the motor rotation. By switching the switch of the coils, the precise rotation of the step motor can be achieved in turn. The control signal can accurately control the rotation of the motor to achieve positioning and control.

The stepper motor has the characteristics of accurate position control, high positioning accuracy, reliable work, and small noise. It is often used in the fields of precision instruments, robots, electronic equipment. Its unique working principle enables the stepper motor to accurately operate without feedback signal, which improves the efficiency and accuracy in applications and reduces production costs.

The step motor is a motion execution agency that converts the pulse signal into corner displacement or line displacement. Taking the most used hybrid stepping motor as an example, its main features are as the followings.

High loading capacity. Its speed is not affected by the load size. Unlike ordinary motors, the speed will decrease when the load is increased. The speed and position of the step motor have strict requirements.

Convenient control. The step motor rotates in "step", and the digital characteristics are obvious.

Simple structure. The traditional mechanical structure for speed and position control are more complicated, and it is difficult to adjust. After the adoption of step motor, the structure of the whole machine is simpler. At the same time, no need special maintenance, and the failure ratio is very low.

100% still stop, no shaking. Because the stepper motor does not depend on feedback such as position, speed, etc., when the input pulse stops, the step motor can be in an absolute stop. The servo motor cannot be absolutely stopped, so the characteristic of the stepper motor is definitely very popular in the need for high precision applications.

Low noise. By proper subdivision setting, the step motor runs very smooth and the noise is small, which is especially suitable for noise sensitive applications.

Of course, there are obvious disadvantages of the stepper motor, such as high running temperature. Although it does not affect the service life of the stepper motor, it is not suitable for heating sensitive applications. However, with the implement of the step drive control algorithm, the input current adjustment range is getting larger and larger, which helps to reduce the motor heating significantly.
