摘要
以六相双Y移30°感应电机为对象,从建立电机数学模型入手,导出状态空间方程,应用特征值稳定判据分析多相感应电机的稳定性。该方法适合线性化的系统在稳定工作点附近微小振动的稳定性分析。针对电机定、转子参数和转动惯量的变化,对系统稳定性进行实例计算和分析。
The state space formula of a six-phase double-Y connection induction motor under 30° phase-shift is gained, by means of the established mathematic model. The stability of multi-phase induction motors is judged by the stable eigenvalue. This method is suitable for the stability analysis of the micro-vibration near the working point in the linear system. The stability of the system is calculated and analyzed through an example against the change of parameters of stator and rotor and rotating inertia.
