基于气隙功率补偿改善电机低速性能方法

针对电机在低速运转时的性能不佳的问题。文章提出的基于气隙功率补偿改善电机低速性能方法。主要利用非线性气隙功率补偿方法，同时还充分结合矢量控制和标量控制的特点，对系统低速运行时的电阻压降和转差频率进行了相应的补偿试验结果表明该方法在电机低频运行时速度平稳，速度静差小。

Based on the air gap power compensation method to improve low speed performance

For the motor at low speed problem of poor performance. This paper proposes gap-based power compensation method to improve low speed performance. Main power compensation method using nonlinear gap, but also fully integrated vector control and scalar control characteristic of the system is running low resistive voltage drop and slip frequency compensation corresponding experimental results show that the method when the motor is running low steady speed, static speed difference is small.
