摘要
介绍一种无速度传感器异步电动机拖动系统的再启动方法。该方法是基于异步电动机在某角频率下发生谐振的阻抗特性来实现,无须高速运算,能利用低成本的处理器来完成。其方法的有效性已通过对5.5千瓦的异步电动机实验和仿真加以证实。
This paper propose a restart method for an asynchronous motor drive system without speed sensor. It is based on the characteristic of the asynchronous motor impedance which is resonant for a frequency corresponding to the angular rotor speed. Since high speed ACR are not required, can be implemented by using a low cost processor. The validity of the method is verified by simulation and experiments, using a standard 5. 5kW asynchronous motor.
