Abstract:
A permanent magnet electric machine with optimum motoring efficiency is disclosed. It is adapted for use in a hybrid electric vehicle powertrain. An asymmetric magnetic flux distribution pattern in the rotor of the machine is established by asymmetrically positioning rotor openings relative to rotor magnets to improve operating efficiency of the machine when it is in a motoring mode.
