Product Specification

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.

Currently, stepper motors are widely used in the field of motion control. Below is a brief introduction to several issues that need to be noted when use hybrid stepper motors.

The torque of the stepper motor will decrease as the speed increases.

When the stepper motor rotates, the inductance of each phase winding of the motor will form a reverse electromotive force. The higher the speed, the greater the reverse electromotive force. In this case, the phase current of the motor decreases with the increase of frequency (or speed), resulting in a decrease in torque.

The stepper motor can work well at low speeds, but if it exceeds a certain speed, it may not start or there may be strong noise whistling.

The stepper motor has a technical parameter: no-load starting frequency, which is the pulse frequency at which the stepper motor can start normally under no-load conditions. If the pulse frequency is higher than this value, the motor cannot start normally and may experience step loss or rotor blockage. With load, the starting frequency should be lower. If the motor is to achieve high-speed rotation, there should be an acceleration process in the pulse frequency, that is to say the starting frequency should be lower, and then a certain acceleration should be applied to reach the desired high frequency (the motor speed should increase from low speed to high speed).

How to overcome the vibration and noise of two-phase hybrid stepper motors during low-speed operation?

The inherent drawbacks of stepper motors are high vibration and noise during low-speed rotation, which can generally be overcome by the following solutions:

A. If the stepper motor works exactly in the resonance zone, mechanical transmission such as changing the reduction ratio can avoid the resonance zone;

B. The most commonly used and convenient method is to use drivers with subdivision functions;

C. Replace with a stepper motor with a smaller step angle, such as a three-phase or five phase stepper motor.
