The Effects of a Low-Conductivity Rotor Coating Thickness on the Rotor Losses of Axial-Flux Solid-Rotor-Core Induction Motor
The effects of a low-conductivity rotor coating thickness on the rotor eddy-current losses are numerically studied in the case of a three-phase, four-pole, 200Hz, axial-flux (AF) solid-rotor-core induction motor. Finite element analysis (FEA) was applied to evaluate the correlation between the rotor losses and the thicknesses of the coatings. This paper describes the influence of the rotor coating thickness on the rotor eddy-current losses. It is shown that the rotor losses can be reduced more than 25 per cent by dimensioning the low-conductivity ferromagnetic coating on the rotor surface properly.
