ABSTRACT:
An internal permanent magnet machine (“IPM machine”) of the type used, for example, with traction motors and hybrid electric vehicles, includes a rotor having a plurality of equal-sized (e.g., rectilinear) segmented ferrite magnets arranged in one or more layers. The magnets are inserted within rotor slots that are larger than the magnets themselves, such that one or more air gaps are formed adjacent to the magnets in each layer.
