Permanent magnet electromagnetic machine

摘要

An electromagnetic machine is provided. The machine includes a stator (16) extending along a longitudinal axis and having an inner surface defining a rotor receipt cavity. The rotor (38) extends along and is rotatable about the longitudinal axis within the rotor receipt cavity. A plurality of ring assemblies (48) are supported on the rotor and a plurality of magnets (52) are circumferentially spaced about the rotor (38) and extend through the ring assembly (48). Each magnet (52) is generally parallel to the axis of the rotor.
