【Abstract】 A calculating method on each power losses and stators voltage and current of asynchronous motors is given, which is operated in reducing stator losses voltage. Take a cage induction motor driving a load of centrifugal blower as an example,when the flow of the blower is regulated by reducing the stator voltage, the various power losses, the stator voltage and current and practical operating efficiency of the motor are calculated in detail by means of MATLAB. The calculating results are given in tables and figures.更多还原
