Tips: The difference between stepper motor and other control motors

The biggest difference between a low cost stepper motor and other control motors is that the stepper motor receives a digital control signal (electric pulse signal) and converts it into an angular displacement or linear displacement corresponding to it. It itself is an executive element that completes the digital mode conversion. Moreover, it can be open-loop position control, input a pulse signal to get a prescribed position increment. Compared with the traditional DC control system, best stepper motor has a significantly lower cost and almost no system adjustment is required. The angular displacement of the stepper motor is strictly proportional to the number of pulses input, and it is synchronized with the pulse in time. Therefore, as long as the number of pulses, frequency and phase sequence of the motor windings are controlled, the required rotation angle, speed and direction can be obtained.
