Abstract :
In this paper the experimental investigation of high speed squirrel cage induction motor (750 Hz, 2 pole) has been presented. Measurement of the equivalent circuit parameters has been discussed in detail. For no-load, stand still test was used instead of light running test. A numerical technique was used for the computation of bridge leakage reactance of the closed rotor slot for various values of rotor bar current. The computed values were compared with the measured one. For evaluation of performance of the motor, equivalent circuit approach was adopted taking into account the nonlinearity of various parameters. Stress distribution in the rotor lamination was also computed using the finite element method for various rotor slot-bridge heights
