【摘要】 采用整距集中绕组的多相感应电机通常注入一定的三次谐波电压来提高电动机铁磁材料的利用率和增加电动机的输出转矩。为了验证该理论的准确性,在MATLAB/Simulink平台中建立计及基波和3次谐波电压共同作用下的十五相电机模型,并用样机进行了相关实验。仿真与实验的结果表明了该方法的可行性,为逆变器PWM供电电压控制方式提供了理论参考,且有益于实际工程多相电机的优化设计。更多还原

【Abstract】 The multiphase induction motor studied in this paper features full-pitch concentrated stator windings and third harmonic injection to improve its average magnetic loading and output torque.In order to validate the effectiveness of such techniques,this paper establishes a simulation model of the fifteen-phase induction machine with both the fundamental and third harmonic current excitations.The simulation model is validated against experimental testing.The good agreement between simulated and experimental results demonstrates the accuracy of the model.The paper also serves as theoretical guideline for the PWM control and the design of multiphase motor.更多还原
