矢量控制系统中异步电动机参数的估算和测量

Parameter Estimating and Measuring of Induction Motors for Vector Control Systems

异步电动机矢量控制系统需要电动机电阻和电感参数。介绍了在调试时,面对1台电机如何估算和测量这些参数,方法有:用电动机铭牌或样本数据估算参数,通过空载和短路实验测取参数,利用变频器测取参数及在运行中修正参数。这些方法也是设计调速系统中自调试功能的基础。

Induction motor vector control systems need resistance and inductance parameters of motor. How to estimating and measuring the parameters when you face on a motor was introduced. The methods are： estimating parameters from motor name plate or catalogue; measuring parameters by means of motor no-load and short-circuit tests;measuring parameters by means of inverters;correcting parameters during motor operat- ing. These methods are the bases of self-adjusting function designing of inverters also.
