摘　　要：针对笼型无刷双馈电机稳态运行时的转矩角(或称功角)的物理含义不清的问题,从分析笼型无刷双馈电机内部磁场的角度入手,推导笼型无刷双馈电机在稳态时电磁转矩的解析表达式,得到了转矩角的计算公式,在此基础上揭示转矩角的物理含义。通过有限元仿真,验证了理论推导的正确性。研究结果不仅有助于简化笼型无刷双馈电机稳态仿真过程,也为更深入地理解笼型无刷双馈电机稳态工作时的内部能量转换机理提供了一定的理论基础。In view of the unclear physical meaning of the torque angle(or power angle)of cage rotor brushless doubly-fed motors in steady state operation,the electromagnetic torque of the motors in steady state was derived from analyzing the internal magnetic field of the motors,and the analytical expression for the torque angle calculation was obtained.On this basis,the physical meaning of the torque angle of the motors was revealed.By finite element simulation,the theoretical derivation was validated.The research results not only help to simplify the steady-state simulation process of cage rotor brushless doubly-fed machines,but also provide a theoretical basis for a deeper understanding of the internal energy conversion mechanism of cage rotor brushless doubly-fed machines in steady state operation.
