What are the applications of stepper motors in the machinery industry?

Manipulator is the earliest industrial robot and the earliest modern robot. It can replace people's heavy labor to realize the mechanization and automation of production, and can operate in harmful environment to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, electronics, light industry, atomic energy and other departments.

 

Stepper motor is an open-loop control element that converts electric pulse signal into angular displacement or linear displacement. In the case of non overload, the speed and stop position of the motor depend on the frequency and number of pulses of the pulse signal, which is not affected by the load change, that is, add a pulse signal to the motor, and the motor will turn a step angle. The existence of this linear relationship, coupled with the stepper motor has the characteristics of only periodic error and no cumulative error. It makes it very simple to control with stepping motor in the field of speed, position and so on.

 

Although stepper motor has been widely used, stepper motor can not be used under conventional conditions like ordinary DC motor and AC motor. It must be composed of double ring pulse signal and power driving circuit before it can be used in the control system. Therefore, it is not easy to use stepping motor well. It involves many professional knowledge such as machinery, motor, electronics and computer.
