摘　　要：采用单片机AT29C51对步进电机进行控制,通过IO口输出的具有时序的方波作为步进电机的控制信号,信号经过芯片SI-7300驱动步进电机；用4X4的键盘来对电机的状态进行控制。PMM8731是步进电机脉冲分配器,SI-7300是高性能步进电机集成功率放大器。它们和单片机一起可构成一种高效电机控制驱动电路。作者介绍了PMM8713与SI-7300的功能,给出了由它们组成的功率驱动电路及其在步进电机上的应用方法。One-chip computer AT89C51 is used to control a step electrical motor, which has a sequential square wave output through an I/O pos as its control signal driving the step motor through chip SI-7300 ; Also, the state of the step motor is controlled with a keyboard of 4 × 4. PMM8731 is a pulse distributor of the step motor, SI-7300 is a high performance integrated power amplifier of the step motor. They can form a kind of high - efficient electrical motor control and drive circuit with one - chip computer. The functions of PMM8713 and SI-7300 are introduced, providing a power driving the circuit and an application method to step motors.
