Abstract
Systems and methods for enhanced techniques for analyzing induction motors. An example method includes accessing circuit model information associated with an induction motor (IM), the circuit model information representing rotor bars of the IM as each including respective rotor segments. Rotor segment nominal currents associated with the rotor segments are determined, with the determination being based on performing finite element analysis (FEA) over a grid and use of a linearized circuit model. Rotor segment ripple currents associated with the rotor segments are determined, with the determination being based on performance of FEA to extract flux ripple samples over the grid, with the flux ripple samples being transformed into a time-varying rotor flux ripple signal, and with the rotor segment ripple currents being determined based on the time-varying rotor flux ripple signal. Losses associated with the IM are determined.
