AXIALLY ASYMMETRIC CONFIGURATION FOR INTERIOR PERMANENT MAGNET MACHINE

摘要

An interior permanent magnet machine includes a rotor having a central axis and a plurality of axial segments. The axial segments include a first axial segment and a second axial segment positioned adjacent to each other in an axial direction. Each of the axially-spaced segments includes at least one pole defining a respective angular configuration characterized by respective first, second and third angles. The first axial segment defines a first set of angular configurations and the second axial segment defines a second set of angular configurations. The rotor is configured to have an axially asymmetric configuration such that the first set of angular configurations is different from the second set of angular configurations.
