Abstract
In this paper, we propose a new type of rotor construction in the permanent magnet synchronous motor. By using plural permanent magnets for one-role of the rotor, it is possible not only to reduce space harmonics of air-gap fields but also to provide spacs for damper windings in the inter-pole space. The dimensions of the plural permanent magnets are derived by Fourier analysis. Based on the investigation by numerical analyses. we propose an optimal rotor construction in view of both the reduction of space harmonics and the damping effect.
