Analytical Design and Finite Element Analysis of High Speed, Axial-Flux Permanent Magnet Synchronous Motor

چکیده مقاله

This paper explores the design, analysis and simulation of a high speed disk-type (axial flux) permanent magnet (AFPM) synchronous motor. This motor has rated power 0.5 hp at speed of 60,000 rpm used in some special industrial applications. The design of high speed AFPM motor is performed using analytical relations, and sizing of various components including dimensions, magnetic specifications and materials are presented in details. To validate the performed analytical design, the designed motor is modeled using finite element analysis (FEA) in Maxwell software. The motor behavior and characteristics are investigated in steady state using magneto-static analysis as well as transient state by transient analysis of Maxwell software. The results of finite element analysis confirm the analytical design results and there is good agreement between both analytical and FEA methods for torque, efficiency and flux density quantities.
