Abstract [en]

Traction motors are thermally pressed to obtain a high torque per unit volume at the same time as a relatively high frequency is used. Because of the high frequency the phenomenon skin effect and proximity effects appear, this is explored in the thesis. To find a link between the parasitic and thermal effects on the insulation is important. In this thesis, a finite element model of the Flux 2D suitable for skin effect analysis is developed; also a thermal network has been developed to find thermal hotspots in the stator slot. In this thesis, sinusoidal supplies for two operating points are studied and triangular sinusoidal PWM supply is as well studied for the nominal operating point.
