Stepping motor is an open-loop control element stepping electric part which transforms electric pulse signal into angular displacement or line displacement. In the case of non-overloading, the speed of the motor, the position of the stop only depends on the frequency of the pulse signal and the number of pulses, and is not affected by the load changes, when the stepper driver receives a pulse signal, it will drive the stepper motor in the direction set to rotate a fixed angle, called "Step Angle", Its rotation is run at a fixed angle step-by-step. The angular displacement can be controlled by controlling the number of pulses to achieve accurate positioning, and the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency to achieve the purpose of speed regulation.
The DC power is converted into time-sharing power supply, multiphase timing control Current, with this current for stepping motor power supply, stepper motor to normal operation, the driver is for stepping motor time-sharing power supply, multi-phase timing controller.
Although Stepper motors have been widely used, stepper motors are not as common as DC motors, and AC motors are used under conventional conditions. It must be composed of a double-ring pulse signal, power drive circuit, and other components of the control system can be used. So using a good stepper motor is not easy, it involves a lot of expertise in machinery, motor, electronics and computer.
Stepping motor, as an actuator, is one of the key products of electromechanical integration and is widely used in various automatic control systems. With the development of microelectronics and computer technology, the demand of stepping motor is increasing, which has been applied in every national economy field.
Stepping motor is a kind of actuator which transforms electric pulse into angular displacement. In layman's words: When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle (i.e. step angle) in the direction set. The angular displacement can be controlled by controlling the number of pulses to achieve accurate positioning, and the speed and acceleration of motor rotation can be controlled by controlling the pulse frequency to achieve the purpose of speed regulation.
