提出了一种新型的分相爪极感应电机。定子铁芯采用软磁复合材料（SMC）。在描述了机器的工作原理之后，提出了线启动、分相、爪极、IM的新结构，并讨论了在效率、转矩密度、谐波和成本方面的新机器特征。几种拓扑结构进行了研究。设计了一个200瓦的原型，并与具有相同功率水平的普通IM进行了比较。结果表明，爪极感应电动机的材料成本与普通径向磁通感应电动机相当，效率高几个百分点，转矩密度高得多。通过优化定子磁极的尺寸和形状，有效地减少了空间谐波。
In this paper, a novel split-phase, claw-pole, induction machine (IM) is proposed. Soft magnetic composite (SMC) material is used in the stator cores. After a description of the machine operating principles, the novel structure of a line start, split-phase, claw-pole, IM is presented, and the novel machine features in terms of efficiency, torque density, harmonics, and cost are discussed. Several topologies are investigated. A 200-Watt prototype is designed and compared to a normal IM with the same power level. It is found that the claw pole IM has comparable material cost to the normal radial flux induction machines with the advantages of several percentage points higher efficiency and much higher torque density. The spatial harmonics are effectively reduced by optimum sizing and shaping of the stator poles.
