摘　　要：基于磁场调制原理工作的永磁(PM)游标电机具有低速、大转矩特性。然而,和传统永磁电机类似,永磁游标电机的励磁磁场由永磁体产生,气隙磁场相对恒定难以调节,宽调速范围运行能力受限。结合"混合励磁"设计方法,通过在分裂齿式永磁游标电机调磁小齿间引入混合励磁绕组,该文研究了一种磁场调制型双馈无刷混合励磁电机;结合有限元方法,介绍了该电机的基本结构和运行原理,揭示了其低速、大转矩并具有宽调速范围特性内在机理;设计了该电机的驱动控制系统,对其静态性能进行系统测试,验证了理论分析与仿真计算的正确性。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.
