Stepping Motor Working Principle


Stepper motor is an inductive motor, it works by using electronic circuits, DC current supply phase sequence control, powered by this kind of current, step motor can work regularly. The driver is the multi-phase timing controller that provides the stepping motor with time-sharing power. Though stepper motor has been widely applied, but it is not like a normal DC motor. To use AC motors in general operation, it only can work since it must be composed of double pulse signal, power driving circuit control system. Thus, it is not easy to use stepper motors properly, it involves in machinery,motor,electronic,computer and other professional knowledge.


How to Overcome the Disadvantages of Stepping Motor


Vibration and noise is the inherent shortcomings of stepper motors, when they are rotating in low speed, generally we can adopt the following solutions to overcome:

A. For instance, a step motor is working in resonance district, it can avoid resonance district by changing reduction ratio and other mechanical rotation.

B. There is also a commonly used and easiest method, that is to match a driver with subdivision function.

C. Using a step motor with smaller step angle, such as 3-phase or 5-phase stepper motor.

D. Exchanging into servo motor, it can almost overcome vibration and noise completely, but the cost is too high;

E. Adding magnetic damping device on a step motor, it is already come into the market , but the mechanical structure would be changed a lot.


Prostepper also provide OEM and ODM for a lot of BRAND-NAME companies.
