Performance evaluation of permanent split-capacitor single-phase induction motor for ceiling fan application

Abstract

The parameters of a permanent split-capacitor single-phase induction motor can be estimated by conducting the DC test, blocked rotor test and no-load test which later can be used to facilitate the prediction of motor torque-speed characteristics. To improve further its performance, an exact motor model is simulated and investigated in 2D finite element analysis under influence of different capacitor values, winding turn ratio and impedance ratio. A prototype is built and tested. Experimental results are compared with those obtained in 2D finite element analysis.
