摘要
为深入研究适用于大推力密度场合的新型动初级六相直线感应电动机的性能,对其数学模型及工作特性进行了研究。首先,将该电机初级绕组布置于动子上,提高了电机的效率和功率因数;然后,建立了abc坐标系和dq0坐标系的基本数学模型,据此阐述了电机内部复杂的电磁耦合关系;最后,基于T型等效电路,分析了大推力六相直线感应电动机的工作特性并进行了试验。试验结果与计算结果吻合较好,验证了模型的正确性。
This study involves the mathematical model and performance characteristics of a new type of dynamic primary six-phase linear induction motor for its fitness in fields of large thrust density.Initially,the primary windings are arranged on the rotor,which improves the efficiency and power factor of the motor.Then the basic mathematical equations in abc and dq 0 coordinate systems are formed respectively,in the light of which the complicated electromagnetic coupling relationship inside the machine is illuminated.The characteristics of large-thrust six-phase linear induction motor are analyzed based on T type equivalent circuit,and relevant experiment is conducted.The good agreement of the experimental results with the calculated results verifies the correctness of the model.
