Variable speed rotor with slow rotation mode

Last updated:

Abstract:

An exemplary method includes controlling a rotation rate of a rotor in a vehicle, detecting that an electric motor system is electrically energized and rotating the rotor at least at a minimum rotation rate that is greater than zero in response to the electric motor system being electrically energized. The rotor may be rotated at least at the minimum rotation rate when the electric motor system is energized and the motor is turned-off.
