Abstract :
In the present paper, the influence of the supply from PWM inverter in the heating distribution in induction motor is presented. The squirrel cage induction motor rated at 2.2 kW; 380 V; 50 Hz; 1420 rpm, has been thermally tested while being supplied alternatively from PWM inverter and sinusoidal voltage source. Many thermistors were placed in the rotor and stator of the motor. Temperature measurements were taken with a complete acquisition system which is used for precise testing and investigating thermal process. Heating curves were obtained in the thermistor points. The results obtained using sinusoidal and nonsinusoidal voltage supply were compared under several load conditions
