Abstract

The effect of inverter supply on the eddy-current losses in the laminated core of a synchronous machine is studied. A 2D finite element model including a dynamic model for the eddy currents in the core laminations is applied to predict the machine losses by numerical simulations. A synchronous extruder motor is simulated both with sinusoidal and pulse-width modulated voltage supplies in different operating points and the eddy-current losses both in the stator and the rotor are studied. The rotor additional inverter losses are found to be load-dependent while the stator additional losses remain constant independent of the loading.
