Abstract :
In this paper, design of a new interior permanent magnet (IPM) machine with very wide constant power operation range is presented. It has been seen that segmentation of the pole magnets and presence of iron bridges between magnet segments provide an inherent flux-weakening capability to the IPM rotor. Consequently, a very wide flux-weakening range is achievable with standard distributed stator winding. The flux-weakening capability of the new rotor was compared to a conventional IPM rotor using the same stator. The paper also presents the design optimization process and experimental verification of performance characteristic of the proposed machine as a case study of a 42 V alternator operation in which the constant power speed range is from 600 to 6000 r/min
