Abstract

A motor-generator system for hybrid electric internal combustion engine applications includes a selectively-engageable motor-generator located co-axially with a front end of the engine crankshaft. The motor-generator system includes at least a first rotor rotationally coupled with the crankshaft and an axially-displaceable stator which is held against rotation relative to the engine. Preferably, a motor-generator controller controls an actuator to axially displace the stator between engaged and disengages states. When in the engaged state, the stator electromagnetically interacts with the rotor to generate electric energy from crankshaft-supplied torque or to produce torque to deliver to the crankshaft and/or an engine accessory drive. The motor-generator system may have multiple axially-displaceable stators and rotors to increase the output of the motor-generator system.
