摘要：
A system for cranking/starting a combustion engine and for generating electrical power during engine operation uses an inverter-driven, high efficiency permanent magnet synchronous machine as a cranking/starting motor during a start mode and as an alternator during a run mode. A modified planetary gear assembly provides sufficient torque multiplication during the start mode to enable the synchronous machine to start the engine. One-way clutches allow the planetary gear assembly to provide the torque multiplication in the start mode and 1:1 coupling between the engine crankshaft and the shaft of the synchronous machine after the engine has been started and is operating.
