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。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.
