Figure 7.
Line graph comparing measured (solid blue) and simulated FEM Model 1 (dashed orange) and Model 2 (dotted green) phase B current waveforms over time, showing Model 2’s higher fidelity.The photograph presents a laboratory motor testing setup. A 3 phase induction motor is mounted on a frame and connected with several wires. A shaft extends from the motor to a torque and speed meter on the right. The lower section contains analogue meters, switches, cables, and an N I current, voltage, torque, and speed D A Q acquisition system. Callout arrows point to the motor, the torque and speed meter, and the acquisition system.

Comparison of measured (experimental) and simulated (FEM) phase B current waveforms for the healthy motor condition at nominal load; two FEM modeling approaches are presented,with Model 2 showing higher fidelity
