A power transmission apparatus, which is disposed on a power transmission path from an output shaft of an internal combustion engine to a transmission in a vehicle, is provided with a rotating electrical machine including a rotor and a stator. The rotor is coupled to a synchronous rotating member that rotates synchronously with the output shaft of the internal combustion engine, and takes a central axis of the output shaft of the internal combustion engine as a rotating shaft. The stator is fixed to a fixing member on a non-rotating side with respect to the synchronous rotating member, and faces the rotor with a first gap therebetween.

A rotating electromechanical machine has a rotor having at least one current-carrying winding and at least one rotor-mounted sensor configured to sense a machine property or parameter during machine operation. Rotor-mounted circuitry dynamically modifies at least one property of the current-carrying winding during machine operation in response to the sensed machine property or parameter.

A rotor of a wound rotor synchronous motor is manufactured by forming a rotor core using a plurality of core blocks, and fitting bobbins with a coil wound onto the core blocks. In particular, the core blocks are connected such that tops of the bobbins extend from bobbin bodies and are connected with tops of other bobbins fitted on the adjacent core blocks. Additionally, a molding material may be injected into spaces between the core blocks.
