摘要
多套多相感应推进电机切套减额稳态运行时,与负载的匹配性能直接关系到推进系统的可靠性。该文以三套五相绕组构成的十五相感应推进电机为研究对象,针对电机不同套数绕组投入/切出减额运行工况,重新计算了对应的定、转子参数,并应用分布磁路法计算了计及饱和变化的励磁电抗,建立了电机对应不同套数绕组运行时的等效电路,结合螺旋桨负载机械特性,计算了十五相感应推进电机切套减额运行时与负载相适应的最大输出转矩。对十五相感应推进电机原理样机进行切套减额运行实验,实验结果与计算结果吻合较好,验证该文所提分析方法的正确性。
The reliability of the propulsion system is directly related to the performance of load matching for multi-phase induction motor with different sets of winding operation.In this paper,a fifteen-phase induction motor with different sets of five-phase winding derated operation is investigated.First,the stator and rotor parameters are recalculated.Then the magnetic reactance considering the change of magnetic circuit saturation is recalculated by a distributed magnetic circuit approach.Variable parameter equivalent circuit of fifteen-phase induction motor with different sets of winding operation is established.The maximum output torque matched with propeller load can be predicted for the fifteen-phase induction motor with different sets of five-phase winding derated operation.The output torque of a prototype fifteen-phase induction motor are measured by a derated test with different sets of five-phase winding out of service.The analytically predicted results are compared with the measured results,where good agreements are achieved.
