摘　　要：介绍了一种具有磁阻效应的新型永磁式有限转角直流无刷力矩电动机,对该电动机定转子基本结构、工作原理、静态定位力矩、精确定位方法等进行了分析与研究,采用AT89C2051微型单片机通过三相桥式逆变电路实现了两相有限转角无刷直流力矩电动机的电流换向、正/反转与定位控制。实验证明该电动机的静态定位力矩大,无须位置传感器即可实现高精度0°、45°和90°三点定位。A novel permanent magnetic limited angle DC brushless torque motor(LABLTM)based on reluctance effect is introduced in this paper.Its basic instruction,working principle,static orient torque,and orientating precisely method are discussed.The three phase bridge inverter and AT89C2051 single-chip computer are used to realize the current commutation,bi-direction motion,orientating control of two phases LABLTM.Tests show LABLTM has high static orient torque,and is able to orient precisely at 0°、45°and 90°three points without position sensor.
