Analytical Method of No-Load Iron Losses of Axial Flux Amorphous Alloy Permanent Magnet Motor
摘要
Abstract
The core loss of axial flux permanent magnet motor will decrease a lot when the silicon steel core is replaced by the amorphous alloy core in consideration of the outstanding low power loss characteristics of amorphous alloy material, but the loss structure of amorphous alloy motor will be different from the silicon steel motor. The key for design and optimization an amorphous alloy axial flux permanent magnet motor is the fast and accurate calculation of no load iron losses during the original designing stage. In this paper, because of the large time consuming of three dimensional time step finite element analysis method, the present multilayer coupled model was further improved, the analytical methods of air gap flux density, stator core loss and permanent magnet eddy current loss were derived, and an analytical model of no load iron losses was then established. The analytical calculation results were compared with the results obtained by three dimensional FEA method, and it is shown that, the average calculation error of no load iron losses is 9.42%. The influences of slot width and air gap length to the no load losses were analyzed using the proposed analytical method, and the results show that, it is more effective to reduce the iron losses by narrowing the slot width.关键词
