单相异步电机的调速方法

Speed Governing Method of Single-phase Asynchronous Motor

通过电容单相异步电机的L型电路图、调速原理,介绍了高速联接的计算方法,假设转差率s不变的情况下,通过实验或者其他计算方法等计算电机的电阻、电抗、阻抗参数;通过介绍的计算方法计算出各绕组的电势等参数,进一步计算出电流,计算出该转差率s的转矩、损耗等。并通过效果分析,对比高、低转速的转矩大小,达到调速目的。

The calculation method of high speed connection was introduced by the L circuit diagram and principles of speed regulation of capacitance of single-phase asynchronous motor.Supposing the slip s was constant,we calculated the resistance,reactance and impedance parameters of motor through testing and other calculation methods.And based on these method,we can also get electric potential parameters of windings,furthermore calculate the current and the torque、loss of this slip s,etc.Through the effect analysis,the high and low speed torque is compared to achieve the goal of speed regulation.
