磁阻同步电动机的稳定性研究

摘要为研究轴向叠片各向异性(ALA)转子电机主要参数对电机稳定性能的影响,采用小信号扰动法建立了电机的线性数学模型,并计算了不同参数在不同频率下的主导特征值轨迹,获得了各参数对电机稳定性的影响规律,为设计电机提供了理论依据。此外,在空载状态下,对样机分别进行了恒压频比变频起动手动升频和自动升频实验,发现电机具有较好的稳定性与快速响应性能。 In order to study the influence of the main parameters of axial laminated anisotropic(ALA)rotor motor on the stable performance of the motor,the small signal disturbance method is used to establish the linear mathematical model of the motor,and the dominant eigenvalue trajectories of different parameters at different frequencies are calculated.The influence regularity of each parameter on the stability of the motor is obtained,which provides a theoretical basis for the design of the motor.What's more,in the no-load state,the experiments of constant voltage frequency ratio variable frequency start-up have been carried out.The experimental results show that the motor has good stability and fast response performance.
