    The basic structure of the motor drive

    The basic structure of the stepper motor drive circuit is shown in Fig. The stepping motor directly connected to AC or DC power supply does not move, and the driver circuit must be used simultaneously in order to perform its functions. Drive (drive circuit) by a decision to change the order of the control circuit (or logic) and controls the output power of the motor commutation circuit (or power circuits (power stage)), whose details will be described in a later section .
    The pulse generator generates a command pulse. When the stepping motor according to a certain speed operation, so long as a series of pulses of a certain frequency, you can determine the total rotation angle of the stepping motor, the stop position, acceleration, constant speed, deceleration of the shifting process. Since the pulse generator to control the pulse frequency, also called controllers.
    In the 1970s, also known as the stepper motor pulse motor, this call is due to the motor input command signal or pulse motor winding current pulse current. Called stepping motor rotor from the output operation, namely the relationship between rotor rotating step by step movement.
