Emulating Induction Machine Loss Segregation Procedure with FEM

This paper investigates the segregation of losses in a 5-kW IE3-rated induction machine. The stator and rotor copper, iron core, stray and mechanical losses are experimentally determined using the IEC segregation of losses-method. The loss components determined from the laboratory measurements are compared with simulated ones. Two alternative methods are used to calculate the losses using a finite element software. The first method is post-processing and the second method is to emulate the loss segregation measurement procedure. By emulating the measurements, FEM output values can be used to calculate variable and fixed losses. The results indicate that the measured losses show a good correspondence with both utilized methods.
