Abstract Permanent magnet (PM) vernier motors based on the magnetic field modulation principle have the characteristics of low speed and high torque. However, similar with traditional PM motors, the excitation field of this kind of motors is generated only by PMs. The air gap magnetic field is relatively constant and is difficult to adjust, so the operation speed range is limited. According to the concept of “hybrid excitation” and introducing hybrid excitation windings between the small teeth of a split-tooth PM vernier motor, a magnetic field-modulated doubly-fed brushless hybrid excitation motor was proposed in this paper. The basic structure and operating principle of the motor were introduced based on finite element analysis, and thus the inherent mechanism of its low speed, high torque and wide speed regulation range was revealed. The static performance of the proposed motor was tested systematically through the designed drive control system, which verified the correctness of theoretical analysis and simulation calculation.

Key words： Magnetic field modulation hybrid excitation doubly-fed in-wheel motor
