【 摘 要 】

In this thesis, we develop a 3-D analytical model for the eddy current loss in the permanent magnet for a permanent magnet synchronous machine with a rated power of 1 MW and an efficiency of 97%. In order to achieve an ambitious power density of 8 hp/lb, which is twice the state-of-the-art value, the machine uses an air cooled system for reducing weight. This thesis will predict the eddy current loss in the permanent magnet in the rotor and validate the prediction through a finite element method to make sure the machine will be able to work reliably under rated load. The optimal number of permanent magnet axial laminations will also be determined in this thesis.
