Abstract
High-speed permanent magnet machines are currently being developed for a number of applocations including gas-turbine generator sets and machine tools. Due to the high peripheral speed of the rotor and the relatively high conductively of the magnets used, rotor eddy current loss can be substantial. On the basis of analytical and finite element method, this paper deals with an analytical method for calculating eddy current losses in the rotor with permanent magnet and retaining ring.
