磁阻转子电机开环变频器供电谐波转矩分析

摘要

为了削弱开环变频器供电的谐波电磁转矩在ALA转子电机运行时产生的振荡和噪声,提出了在变频器的输出侧安装适当的电抗器和在转子轴上附加机械惯性阻尼器策略.实验验证了电机的动稳态性能得到明显的改善,表明此方法是有效的.%In order to weaken the vibration and noise of the harmonic electromagnetic torque produced by the working ALA rotor motor with open-loop frequency inverter power supply,methods that mechanical inertial damper is added on the rotor shaft and the proper rector is installed on the inverter side have been proposed.The experiments have proved that dynamic and steady performance of the motor can be improved.The results show that the methods are effective.
