Abstract :
This paper describes the design of a large output power permanent magnet synchronous motor with radial flux distribution. In this paper, two different permanent magnet motor configurations were analysed. Numerical calculations of motor characteristics were performed with a two-dimensional finite element, time-stepping simulation program. The results are presented and the advantages and disadvantages of each rotor construction are discussed
