Abstract :
This paper proposed a PWM control circuit for two-phase hybrid stepping motor based on LMD18245. The circuit uses two pieces of EPROMs and DACs to achieve 1/5 microstepping. Choosing different address of EPROM by selecting the coding switch, it can output different current and number of subdivision. The driver system has quite good characteristic and is quite simple, reliable and versatile.
