57HS130 Series 2 Phase Hybrid Stepper Motors

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.

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.
