Enhanced techniques for analyzing induction motors

A system comprising one or more processors and non-transitory computer storage media storing instructions that when executed by the one or more processors, cause the processors to perform operations comprising:

• determining rotor segment nominal currents associated with an induction motor (IM), the IM being reflected in circuit model information representing a plurality of rotor bars each comprising a respective plurality of rotor segments, wherein the rotor segment nominal currents are associated with the rotor segments, and wherein the determination is based on performing finite element analysis (FEA) over a grid, wherein the grid is periodic with respect to a first electrical angle associated with synchronous speed and a second electrical angle associated with slip frequency, and wherein performance of FEA is limited to positions within respective periods of the first electrical angle and second electrical angle, such that performance of FEA is constrained;
• determining rotor segment ripple currents associated with the rotor segments, wherein the determination is based on performance of FEA to extract flux ripple samples over the grid, wherein the flux ripple samples are transformed into a time-varying rotor flux ripple signal, and wherein the rotor segment ripple currents are determined based on the time-varying rotor flux ripple signal;
• determining one or more losses associated with the IM;
• and
• presenting the one or more losses on a user interface.
