1) Product Description and images

Stepping motor is a kind of motor that converts electric pulse signal into corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates by an angle or advances one step. The angular displacement or linear displacement of the output is proportional to the number of input pulses, and the rotation speed is proportional to the pulse frequency. Therefore, stepping motor is also called pulse motor. Based on the most basic principle of electromagnet, the stepping motor is a kind of electromagnet that can rotate freely. Its action principle is to generate electromagnetic torque by the change of air gap permeability.

5) Product information and advantages

The biggest difference between stepper motor and other control motors is that it receives digital control signals (electric pulse signals) and converts them into corresponding angular displacement or linear displacement.

stepper motor is an actuator that completes digital mode conversion. Moreover, the stepper motor can be controlled by open-loop position, and a specified position increment can be obtained by inputting a pulse signal. Compared with the traditional DC control system, the so-called incremental position control system has significantly reduced cost and hardly needs system adjustment.

The angular displacement of the stepping motor is strictly proportional to the number of input pulses, and is synchronized with the pulses in time.

Therefore, as long as the number and frequency of the pulses and the phase sequence of the motor winding are controlled, the required rotation angle, speed and direction can be obtained.
