ROTATING ELECTRICAL MACHINE SYSTEM AND WIND POWER GENERATION SYSTEM

WIPO Patent Application WO/2014/083687

A1

The present invention provides a rotating electrical machine system having an operation range not narrowed, and capable of sufficiently cooling a power convertor without resulting in performance degradation. The rotating electrical machine system according to the present invention comprises: a first rotating electrical machine constituted by a first stator having a first stator winding and stator core, and a first rotor having a first rotor winding and rotor core and disposed near the inner diameter of the first stator with a prescribed gap therebetween; a second rotating electrical machine constituted by a second stator having a second stator winding and stator core, and a second rotor having a second rotor winding and rotor core and disposed near the inner diameter of the second stator with a prescribed gap therebetween; and a power convertor electrically connected to the first and second rotating electrical machines, and disposed either at the first rotor core or at the second rotor core to rotate when the first and second rotor cores rotate.
