Stepper motor is an electrical pulse into the angular displacement of the actuator Popular point said: when the stepper drive receives a pulse signal, it will drive move a step into the motor according to set the direction of rotation of a fixed point (i.e. stepper angle). Is a kind of induction motor and its working principle is the use of electronic circuits the DC component power supply, multiphase timing control current. This current stepper motor power supply, stepper motor to work properly, drive for stepper motor powered multi-phase timing controller
Stepper motor as the actuator, electromechanical integration is one of the key products, widely used in a variety of automatic control system with. With the development of microelectronics and computer technology, the demand of stepping motor is increasing day by day. It has been applied in various national economy fields. You can by controlling the pulse number to control the amount of angular displacement, so as to achieve the purpose of accurate positioning; at the same time you can by controlling the pulse frequency to control motor rotation speed and acceleration, so as to achieve speed control.
Although the stepper motor has been widely used, but the stepper motor does not like ordinary DC motor, AC motor in the conventional use. It must be composed of double ring pulse signal, power drive circuit and other components of the control system can be used. Therefore, a good use of stepper motor is not easy, it involves many professional knowledge of mechanical, electrical, electronic and computer, etc..
