摘要：

Eddy current losses in rotor permanent magnets (PM) of synchronous machines with concentrated windings are calculated for sinusoidal stator currents. Three different calculation methods are compared in the Finite-Element environment: 1) analytical post processing of FE magneto-static data with multi-move and eddy currents calculated from vector potential, 2) direct FE magneto-static method, 3) time stepping with a FE program. From thermal measurements performed on existing prototype motors the losses in magnets are compared based on the temperature rises in the magnets at adiabatic heating.
