将混合励磁原理与游标结构相结合，提出了一种新型的顺极混合励磁游标电机（CPHEVM），其外转子采用顺极磁铁布置。所提出的电机可以在低速下实现高转矩密度，在高速下实现优异的弱磁能力，这对于电动汽车应用是非常理想的。直流励磁绕组嵌入在调制极之间，这增加了空间利用率，从而能够在不降低转矩能力的情况下实现磁通调节。分别描述了该CPHEVM的结构、工作原理和设计考虑。采用有限元法分析了所选CPHEVM的电磁性能与不同的槽/极组合，包括磁链调节能力，反电磁力，和转矩特性与弱磁控制和没有。
This paper proposes a novel consequent-pole hybrid excited vernier machine (CPHEVM) by combining hybrid excited concept and vernier structure, and the consequent-pole magnet arrangement is employed on outer rotor. The proposed machine can achieve high torque density at low speed and excellent flux-weakening capability at high speed, which are highly desirable for electric vehicle applications. The direct current field windings are embedded between modulating poles, which increase the space utilization ratio to enable flux regulation without decreasing torque capability. The configuration, operation principle, and design consideration of the proposed CPHEVM are described, respectively. Finite-element method is employed to analyze the electromagnetic performance of the selected CPHEVMs with various slot/pole combinations, including flux regulation capability, back-electromagnetic force, and torque characteristics with and without flux-weakening control.
