摘要

针对笼型无刷双馈电机转子设计方法不完善的问题,从分析笼型无刷双馈电机的内部磁场入手,推导了无刷双馈电机在稳态运行时转子电流的解析表达式,利用迭代法在考虑转子电阻的情况下选择最合适的转子导条截面积,为笼型无刷双馈电机的转子设计提供了理论依据。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在设计时快速计算笼型无刷双馈电机转子电流,也有助于优化转子结构设计。
        In view of the insufficient design method for rotor bars of cage rotor brushless doubly-fed motor, the analytical expression for the rotor current calculation of cage rotor brushless doubly-fed motors in steady state was derived starting from analyzing the internal magnetic field of cage rotor brushless doubly-fed motor. The iterative method was used to select the most suitable cross-sectional area of the rotor bar in consideration of the rotor resistance, which provided a theoretical basis for the rotor design of the cage rotor brushless doubly-fed machine. Via finite element simulation, the theoretical derivation was validated. The research results not only help to quickly calculate the rotor current of cage rotor brushless doubly-fed motor during design, but also help to optimize the rotor structure design.
