Abstract: Introduced a two+phase hybrid linear step motor(LPM)driver controled by C8051F005 SCM(single chips microcomputer).Meanwhile,the driver had the functions of constant current chopper,index movements frequency and sine wave equal-breadth even subdivision.The test result indicated that this driver had the good dynamic and static characteristic,the simple structure,the easy operation and can be the partnership equipment for the LPM noumenal R&D(research and development).Through transforming the software parameters,it can be generalized to other LPM’s driving control.Research has a preferable application foreground.
