1. Products Overview

Stepper motor is an executive agency that converts electrical pulses into angle displacement. You can control the angle by controlling the number of pulse to achieve the purpose of accurate position control. At the same time, you can control the speed and acceleration of the motor by controlling the input pulse frequency to achieve the purpose of the speed control.

Step motor, also called as pulse motor is normally classified by structural as: reactive step motors (VR), permanent magnet step motor (PM), and hybrid step motor (HB). Step motor can also be divided into rotation and straight lines according to the form of movement. According to whether there is an encoder, can be divided as open-loop and closed-loop step motors.

Reactive step motor: there are windings on the stator and rotor consisting of soft magnetic materials. The structure is simple, the cost is low, the step distance is small, and it can reach 1.2 °, but the dynamic performance is poor, the efficiency is low, the heating is large, and the reliability is difficult to guarantee.

Permanent Magnet step motor: The rotor of the permanent magnet step motor is made of permanent magnet material, and the rotor is the same as that of the stator. It is characterized by good dynamic performance and large output torque, but this motor has poor accuracy and large steps (generally 7.5 ° or 15 °).

Hybrid Step motor: Hybrid steaming motor integrates the advantages of reaction and permanent magnets both. It has a multi-phase windings, permanent magnet material on the rotor, and multiple small teeth on the rotor and stator to improve the step accuracy. It is characterized by large output torque, good dynamic performance, and small steps, which can meet automation applications which have high precision requirement.

According to the quantity of phases, there are two -phase, three, and five -phase step motors. The most popular is the two-phase hybrid step motor, accounting for about 97%of the market share. The reason is that the two-phase step motor is more cost-effective, and also has satisfactory performance due to subdivision or micro stepping function of its drive.

The basic step angle of a two-phase step motor is 1.8 °/step. Matched with a half-step drive, the step angle is reduced to 0.9 °. Matched with a micro stepping driver, the step angle can be subdivided up to 256 times (0.007 ° per micro step), which can meet the requirement of most 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.
