Abstract:
An electric machine that includes a stator core having a stator core length, a first rotor core portion, and second rotor core portion. A spacer is coupled to the first core portion and the second core portion to at least partially define a rotor core. The rotor core has a length that is greater than the stator core length. A permanent magnet is coupled to the rotor core and has a magnet length. The magnet length is greater than the stator core length.
