Title:
ROTARY ELECTRIC MACHINE SYSTEM AND WIND POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/064747
Kind Code:
A1
Abstract:
Provided is a rotary electric machine system that saves space and achieves a brushless rotary electric machine even when a first rotary electric machine (main generator) and a second rotary electric machine (auxiliary generator) are provided. The rotary electric machine system of the present invention is provided with a first rotary electric machine, a second rotary electric machine, and a power convertor that is electrically connected to the first and the second rotary electric machines, and is characterized in that the first and second rotary electric machines and the power convertor are mechanically connected to a rotary shaft, the outer diameter of the stator of the second rotary electric machine is smaller than the inner diameter of the rotor of the first rotary electric machine, and the stator winding and the rotor winding of the first rotary electric machine and the stator winding and the rotor winding of the second rotary electric machine are arranged so as to overlap in the radial direction.
