摘　　要：采用NE555设计步进电机脉冲产生电路,对EPROM2716进行编程实现脉冲环形分配,并决定四相八拍或四相四拍的驱动方式,电动机的运行方向由74LS191的D1J控制,设计了高低压驱动电路,减少了限流电阻的发热.Pulse circuit is produced for step motor by NE555, pulse distributor is designed by EPROM2716, program in which determines four phases four quadruples or four phase seight quadruples, direction of motor rotating is determined by D1J of 74LS191 ,high and low voltage driver circuit reduces resistance heat.

关 键 词：步进电机 环形分配器 驱动电路
