摘要
异步电机无速度传感器技术克服了安装速度传感器带来的诸多不便与缺点,降低了成本,具有广阔的应用前景。本文着重研究电机方程直接计算法,介绍利用电机方程推导转子速度的方法。并使用saber软件建立异步电机无速传感器调速系统仿真模型。以此为基础,对比估算值与实际值的差异,验证电机方程直接计算法的可行性。
Speed-sensorless induction motor overcomes various inconveniences and shortcomings of the induction motor with speed-sensor when applied in practice.So this technology has a good application prospect.This paper focuses on the direct calculation method,so a method of calculating the speed of rotor is introduced in it.The model of speed sensorless of inductor motor is built with saber software.Based on this model,the difference between the estimated value with real one is compared,as well as the feasibility of the direct calculation method is verified.
