摘  要：采用绕组函数法分析多相感应电动机定子绕组为正弦分布、集中整距和短距分布等形式时气隙磁势谐波的分布，在此基础上简单讨论建立对应的电机数学模型。由于多相电机具有转矩大，定子绕组分布和激励形式灵活的特点，相比传统三相电机其优点显著。

Abstract: The paper analyzed MMF harmonics of air-gap field for different stator windings of multi-phase induction machines，such as sinusoidal distributions，concentrated full-pitch windings and distributed short-pitch windings.The method of winding functions was adopted.Then the mathematical models of multi-phase induction machine were obtained according to the type of stator windings.The multi-phase machines have advantages than the traditional three-phase machines because they have larger torque，more flexibility in winding distributions and power forms.
