Abstract: This study presents practical study of the effect of frequency on the performance and operation of three-phase induction motor. The theoretical review of three-phase induction motor is introduced and the effect of frequency changing on motor operation is discussed. The experimental investigation involved frequency changing from 40-60 Hz by using AC drive. The motor performance under frequency changing at different load conditions. It is found that when the frequency increased from 40-60 Hz the motor voltage increased by 44% with no load and 26.5% with load. The current is in creased by 5% with no load and by 31.5% with load. The temperature of motor is increased by 18.6% with no load and 16.6% with load.
