Simplified Measurement Method of Turn-ratios of Auxiliary Windings in Single Phase Induction Motors for General Purpose

Abstract

The turn-ratio test is required in single phase induction motor to obtain the data necessary to segregate the losses. In this study, for the single phase induction motors for general purpose that are used widely as single phase induction motors it is discussed that the turn-ratio can be derived from the data obtained in the experiment similar to the locked rotor test for the determination of load characteristics in a polyphase induction motor.
