步进电动机恒流斩波驱动器的设计

Designing a Driver of Constant Current and Chopped Mode for a Stepping Motor

设计一种二维三相六拍步进电动机恒流驱动器 .该电路采用集成块和一些较先进的单元电路 .它的特点是体积小、重量轻、绕组电流近似于恒流、精度较高、稳定性好、功耗低、成本低 .

A two dimensional, threc phase, and six beat driver of constant current is designed for a steeping motor. Owing to the adoption of integrated module and some fairly advanced element circuits, the driver is characterized by small in size, light in weight, approximate to constant current in winding current, fairly high in precision, good in stability, low in power consumption, and cheap in cost.
