永磁电机具有高转矩密度、高功率密度、高可靠性、低损耗、高效率等优点，已成为工业生产、交通运输、航空航天等领域的重要组成部分。永磁爪极电机是一种特殊类型的横向磁通电机，与传统永磁电机相比，具有更高的转矩密度。由于没有绕组端部，其轴向空间利用率高，大大减少了绕组的使用量，降低了电机的成本和重量。PMCPM具有体积小、重量轻、转矩密度高、效率高、制造简单等优点，在电动汽车领域具有潜在的应用前景。双定子结构的设计可以提高永磁连续电机的转矩密度、效率和径向空间利用率，有助于扩大其在电动汽车领域的应用。设计了两种不同转子结构的集中绕组永磁同步电动机（PMCPM 1和PMCPM 2），并采用三维有限元法对PMCPM 1和PMCPM 2与传统永磁同步电动机（TPMCPM）的性能进行了对比分析。对PMCPM 1和PMCPM 2进行了多物理场分析。分析了内、外定子过盈装配时的应力。本文提出了一种混合材料铁芯设计方案，定子磁轭采用硅钢材料轧制而成，定子爪极采用SMC模压成型。分析了混合核PMCPM 1和PMCPM 2的多物理场仿真性能。
Permanent magnet motors have become an important component of industrial production, transportation, and aerospace due to their advantages of high torque density, high power density, high reliability, low losses, and high efficiency. Permanent magnet claw pole motor (PMCPM) is a special type of transverse flux motor which has a higher torque density compared to traditional permanent magnet motors. Due to the absence of winding ends, its axial space utilization is high, and the usage of windings is greatly reduced, reducing the cost and weight of the motor. PMCPM has the advantages of small space, a light weight, a high torque density, a high efficiency, and simple production, which have potential for use in the field of electric vehicles. The double-stator structure design can improve the torque density, efficiency, and radial space utilization of PMCPM, which helps to expand their applications in the field of electric vehicles. This article designs two PMCPM with concentrated winding while different rotor structures (PMCPM1 and PMCPM2) and a three-dimensional finite element method is employed to compare and analyze the performance of PMCPM1 and PMCPM2 and the traditional PMCPM (TPMCPM). Multiphysics analysis is carried out for PMCPM1 and PMCPM2. The stress of the inner and outer stators during interference assembly are analyzed. In this paper, a hybrid material core design is proposed, in which the stator yoke is rolled by silicon steel material and the stator claw pole is pressed by the SMC die method. The multiphysics simulation performance of the PMCPM1 and PMCPM2 with hybrid cores is analyzed.
