1. Products Overview

Step motor is a motor that converts the electrical pulse signal into the corresponding angle displacement. For each of the pulse signal, the rotor rotates a certain angle accordingly, and the speed is proportional to the input pulses’ frequency. Therefore, step motor is also called pulse motor.

The biggest difference between step motor compared to other control motors is that it receives digital control signals (pulses) and converts into angle displacement accordingly. Enter a pulse signal to get a specified position increment. Compared with the traditional DC control system, such a so-called incremental position control system, the stepper system complexity and cost are significantly reduced. The angular displacement of the stepping motor is strictly proportional to the number of input pulse, and it is synchronized with the pulse in time. Therefore, by controlling the pulse frequency and pulse quantity, the motor shaft speed, and position can be controlled precisely too.

At the same time, Kaifull has solved many problems of traditional stepper drivers buy the latest patented technologies. There are many middle and high end customers globally, and they highly appreciate our stepper motor and drives very much.

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.
