    ABSTRACT: This paper discusses the control of stator flux and torque in the surface permanent magnet synchronous motor (SPMSM) direct torque control (DTC) system. The study shows the angle between stator flux vector and the applying voltage vector determines the dynamic behavior of stator flux and the angle between rotor flux vector and the applying voltage vector determines the dynamic behavior of torque. Two optimal voltage vector selection strategies for the SPMSM DTC system are proposed. Simulation results testify theoretical analysis.

    ABSTRACT: In order to improve the reliability of the system, a dual-redundancy high-voltage brushless DC motor based on 270 V is designed. According to the structural features of dual-redundancy high-voltage brushless DC motor, the mathematical model is built up, and the calculation formula of torque is derived when the motor work in the dual-redundancy. This paper set up the electromagnetic field model and magnetic-thermal coupling model of a dual-redundancy high-voltage brushless DC motor, carry out the simulation of the motor, and comparatively analyze the EMF, torque and speed when the motor work between single winding and dual-redundancy. The simulation results show that: the Dual-redundancy high-voltage brushless DC motor can achieve same dynamic characteristics with single winding motor, and the torque is twice. Meanwhile, it greatly improve the reliability of the system.
