Mathematical Model and Torque Characteristics on a Brushless DC Motor with Dual-windings

阐述一种用于全电飞机机电作动系统的双绕组永磁无刷直流电动机。该电动机定子上有双重绕组,由两套独立的功率电路驱动形成双通道控制系统。该系统能够实现容错控制以提高可靠性。论文研究了该电动机的数学模型与转矩特性,并给出试验结果。

A permanent magnet brushless DC motor was presented, which will be used for a Electro-Mechanical Actuator (EMA) in a All-Electric Aircraft(AEA). This motor includes double-windings in stator, which are driven by two independent sets of power electronic circuits, thereby it is formed that a electrical driven system with dual control channels. A fault-tolerated operation mode can be used in this system for high reliability. The model of the motor and the torque characteristics are researched, and finally the test data are given.
