笼型异步电动机启动场路耦合时步有限元仿真

针对传统的电路磁路方法和电磁场解析法难以分析电动机动态过程的缺点,以一台笼型异步电动机为例,从运动电磁场的角度出发,建立了该电动机的场路耦合时步有限元计算模型,分析计算了该电动机的空载启动过程。结果表明,使用该模型可以得到比传统方法更为合理的结论。该研究工作对提高电动机的设计制造及运行水平具有一定价值。

FEM simulation of field-circuit coupling time-stepping for starting of squirrel cage induction motors

Aim at the shortcomings in analyzing the motor dynamic process by traditional circuit and electro-magnetic field analytical method,an induction motor serves as an example to establish the field-circuit coupling time-stepping finite element model and analyze the no-load starting process of the motor based on sport electro-magnetic fields.The results show that more reasonable conclusions are achieves by the model than by traditions models.The study possesses some value for improving the level of design and op...
