Abstract	This study describes a technique to determine the core loss in different parts of an induction motor (IM) for any types of electric power supply. To calculate the core loss, flux density waveforms are determined in different parts of the motor. Different forms of Steinmetz equation are used for the core-loss calculation. The coefficients of these Steinmetz equations are determined using the loss data given by the electrical steel manufacturer. Since, the manufacturer data are available for a limited number of frequencies; a curve fitting technique is used here to determine the loss data at required frequency. The proposed technique is tested on an IM with sinusoidal excitation for different load torques and with sine pulse-width modulation inverter supply at different switching frequencies. The core loss obtained from with this technique is also compared with other techniques reported in the literature. A good accuracy is obtained between the measured and calculated core loss using proposed technique comparing to other techniques.
