摘　　要：针对ALA转子电机在变频器供电条件下出现的振荡现象,采用小扰动分析法对电机的稳定性进行了分析,得出了小扰动条件下分析电机稳定性的线性化方程,并由此确定电机振荡原因为特定的转子结构和非正弦供电电源。最后分析了电机参数与电机稳定性的一般关系,所得结果与实验现象相符。Aimed at the oscillating phenomenon occurred in ALA (axially laminated anisotropic) rotor machine drive with a VVVF invertor supply, a set of linearized equations, derived by means of small perturbation, is used for the stability analysis. Results show that the oscillations are caused by the special rotor composition, as well as the nonsinusoidal power supply. Lastly, relationships between the parameters and the stability are discussed in detail, and verified by some well-agreed experimental results.
