Web10 okt. 2024 · 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. Webestimates of vibratory mag torque pulsations at the rotor have been used (mostly by motor manufacturers) for some time [7, 8, 9]. Concordia [7] developed a method for estimating current pulsations for induction motors using the concept of “synchronizing” and “damping” torques, later extended to synchronous motors by Halberg [8].
