Abstract :
In this study, we investigate the output maximization of salient-pole synchronous machines by using small amount of Nd-Fe-B magnets. First, the mechanism of output increase by the additional magnets is revealed by using both finite element method and simple magnetic circuit. Then, the appropriate magnet shape and rotor core design are discussed. The experimental verification is carried out by using prototype machines. The advantages of the proposed design are confirmed.
