Abstract

Algorithms allowing the steady state coupled thermo-magnetic fields to be obtained for electrical machines such as induction machines, permanent magnet synchronous machines with surface magnets or DC-motors are proposed. These machines are thermally anisotropic since they show radial heat flow paths with different thermal conductivities while rotating. The novel method is based on an iteration loop involving a single magnetic finite element (FEM) model and one or two thermal FEM models
