Precise position control at low speeds.

The stepper motor can run smoothly at very low speed without adjusting the gear box, output a large torque, and avoid power loss and angular position deviation.

A stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement.In the case of non-overload, the speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by the load change, that is, add a pulse signal to the motor, and the motor rotates through a step angle.

The existence of this linear relationship, coupled with the fact that the stepping motor has only periodic errors and no cumulative errors.  It makes it very simple to use the stepper motor to control the speed, position and other control fields.

Although stepper motors have been widely used, but stepper motors are not like ordinary DC motors, AC motors are used under normal circumstances.It must be used by the control system composed of double ring pulse signal, power drive circuit, etc.Therefore, it is not easy to make good use of stepper motors. It involves many professional knowledge such as machinery, motors, electronics and computers.
