摘要
由机械不平衡等原因导致的无轴承开关磁阻电机(BSRM)质量偏心问题,造成额外的不平衡径向磁拉力和转子的径向振动,且振动会传递到定子机壳,产生机械噪声的同时影响电机运行性能,限制转速的进一步提升。分析了转子质量偏心对电机悬浮性能的影响,介绍了BSRM转子振动控制原理,设计基于坐标变换和低通滤波器的补偿控制方法,研究传统模拟PID对补偿方法的影响,对该不平衡补偿方法进行仿真,并在一台实验样机上进行实验验证。结果表明,基于坐标变换和低通滤波器的补偿方法能适应不同转子转速并有效补偿转子的同频振动位移,使得转子围绕惯性轴旋转。
Due to the mechanical imbalance, mass eccentricity exists in bearlingless switchedreluctance motor (BSRM), leading to additional unbalanced radial magnetic force and radial vibrationof rotor. Moreover, the vibration would be passed to the stator housing case, which will produce noise,influence the operation performance and limit the speed. In this paper, the principle and influence ofmass eccentricity are analyzed. The compensation method based on the coordination transformation andlow pass filter is proposed, considering the impacts of analog PID. The unbalanced vibration compensationmethod is realized in a prototype. The results show that, the method could compensate thevibration displacement adaptively atdifferent speeds, to make the rotor spin around the axis of inertia.
