摘　　要：基于对PBL3770A驱动芯片和80C51BH单片机研究,提出二相步进电机的控制方案,设计和搭建硬件的驱动电路,实现了控制二相步进电机运转的驱动程序.具体实现了80C51BH对外部脉冲产生中断,产生二相八拍的驱动信号,利用PBL3770A步进电机驱动芯片从而控制电机的正转、反转的半步距转动.经调试仿真及实物操作,结果表明该系统运行正常,达到设计要求.Based on PBL3770A and 80C51BH,this paper proposes the control scheme about the bipolar stepper motor,designs and builts the driving circuit of the hardware,and realizes the driving procedure to control the rotation of the bipolar stepper motor.Special implementation is that the external pulse results in the fact that the 80C51BH produces interruption and the drive signals of two phases and eight steps and it also controls the function of the motor＇s half-step rotation including anti-clockwise rotation and clockwise rotation by PBL3770A.It is proved that the system runs normally and can achieve the designed requirements in tests,simulations and actual operations.
