What is stepper motor
Release time:

Stepper motor is an open-loop control element that converts electrical pulse signals into angular or linear displacement. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, called "step angle", and its rotation is run step by step with a fixed angle. The number of pulses can be controlled to control the amount of angular displacement, so as to achieve the purpose of accurate positioning; at the same time, the pulse frequency can be controlled to control the speed and acceleration of motor rotation, so as to achieve the purpose of speed regulation.
Stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, the DC power into a time-sharing power supply, multi-phase timing control current, with this current for the stepper motor power supply, stepper motor to work properly, the driver is for the stepper motor time-sharing power supply, multi-phase timing controller.
Although stepper motors have been widely used, stepper motors can not be used like ordinary DC motors, AC motors under the regular. It must be used by the double-loop pulse signal, power drive circuit, etc. to form a control system. Therefore, it is not easy to use a good stepper motor, which involves a lot of mechanical, electrical, electronic and computer expertise. Stepper motor as an actuator, is one of the key products of mechatronics, widely used in a variety of automated control systems. With the development of microelectronics and computer technology, the demand for stepper motors is increasing day by day, and they are used in various national economic fields.
