1. Product Overview

Step motor is a motor that converts the electrical pulse signal into the corresponding angle displacement or the line displacement. It can use the quantity and frequency of the pulse to control the rotation (rotation angle, rotation speed) in automation applications. For each of the pulse, the motor rotor rotates a angle or forward, and its output angle shift or line displacement is proportional to the input pulse, and the speed is proportional to the pulse frequency. Therefore, step motor is also called pulse motor.

In the case of non-overload, the speed of the motor and the stop position depends only on the frequency and number of the pulsed input, without being affected by the load change. That is to say, add a pulse signal to the motor, and the motor turns a step distance. The advantage of this linear relationship between pulse and angle rotation, plus that a step motor only has periodic errors without cumulative errors, make step motor widely used in automation speed, position and other control fields easily.

With the development of product research and development of technology, the performance of the step system has been even more improved. If the stepper system is not overloaded, there will be no step loss mostly nowadays, and life time very long, almost no need maintenance, which makes steppers popular and widely used in many kinds of industrial automation motion control applications.

Kaifull two-phase, three-phase, and five-phase hybrid step motors are made of high-temperature permanent magnet and high-quality cold-rolled steel sheets. Our stepper motors range is very rich, covering 20mm to 150mm in frame size. At the same time, there are all-in-one step motors that integrated with drivers, closed-loop stepper motor, and with brake stepper motor etc..

Generally speaking, the characteristics of step motor are:

Easy drive.

No matter how the input current changes, as long as the load can be driven, the step motor moves according to the minimum angle.

No feedback signal is required. The step motor moves according to the pulse frequency and quantity given by the drive, and does not need to rely on the motor actual status feedback.

The positioning error does not accumulate. The reason why the stepping motor does not accumulates is because it does not need to know the actual location, but only needs to know the number of rotating steps. Therefore, the step motor only needs to receive the signal of each step, and then move according to the step angle. It is not necessary to know the starting location or target location. This can avoid the problem of accumulating errors. In addition, the working principle of the stepper motor makes the movement discrete and performed from a specific angle without a continuous accumulation error.

Stepper motor driver principle is simple and easy to develop control system.

Step motor has the characteristics of high power density, high output torque, low noise, low vibration and smooth rotation, high energy conversion efficiency, stable and reliable, long life etc. At the same time, our company supports the flexible customization, too.
