抄録

Highspeed Permanent Magnet Synchronous Machines (P. M.) become more and more popular for their small weight and low noise. As the residual magnetism of rare-earth magnets is temperature dependent, eddy-current losses in the supporting-ring of radial-airgap constructions play an important role in the design of such machines. This paper presents a solution for the harmonics, due to slotting, in the flux-density waveform on the surface of the supporting-ring, using a Fourier-Series-Method. A fast approximate solution for loss-calculations at no-load is shown and the results are compared with measured values of an experimental machine, rated at 1000kW, 1250V, 15000rpm.
