Stepper motor as the executive element, it is one of the key products of electromechanical integration, widely used in all kinds of automation control system. With the development of microelectronics and computer technology, increasing demand for stepper motor, are used in the field of the national economy. stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper motor power supply, stepper motor can work normally, stepper motor driver for step motor of time-sharing power supply, multiphase sequential controller because of the influence of the winding inductance, current in winding will rise according to law. So in order to obtain good performance of high frequency, make winding change steep rise in the current waveform, can use the method of high voltage driver to shorten the time of the current rise to reference current, can achieve good pull out torque and improve the start performance of motor. because half step single and two phase incentives step resolution doubled, and the motor will run more smoothly, and the basic steps of two-phase incentives phase coil utilization rate is high, can produce a large torque, at the same time can produce electromagnetic damping, weaken or eliminate the oscillation phenomena, these two kinds of control mode is often used. in the same way, when the basic step two phase driving mode change as the basic step of single-phase incentives driving mode, to maintain constant output torque, phase current must also for the phase current of The Times.
