Özet

One of the major issues in the design of high-speed permanent magnet (PM) motors is the magnet losses. Magnet eddy-current losses are one of the significant loss components and it is related to the motor frequency directly. In this paper, a detailed analysis of a high-speed brushless permanent magnet synchronous motor is performed. Magnet losses as well as other loss component such as iron and copper AC and DC losses are also investigated comprehensively for the reference motor selected.
