摘　　要：本文设计了一种适合三相反应式步进电动机的高性能细分驱动器,在功率驱动中采用了大功率VMOS器件,在细分环形分配器设计中采用了两片GAL,使整个电路具有较高的运行性能,开关迅速,功耗小,体积较小,可靠性较高。A micro-stepping driver with high performance for VR step motor is designed in this paper. In power drive circuit, a kind of power transistor VMOS is adopted. In designing of the micro-step circular distributor, two pieces of GAL and EPROM are used. All the changes made the overall circuit has a higher running performance, fast switching time, small power dissipation and volume.
