Title:
ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2016/103740
Kind Code:
A1
Abstract:
The present invention is capable of simultaneously being in an electrically driven mode and a power generation mode that share a single machine and a single rotor 5 and of continuously generating power. A rotating electric machine has: a freely rotatable rotor having permanent magnets circumferentially arranged thereon and a first magnetic field part and second magnetic field part respectively formed on the outer and inner surfaces of the rotor; a first stator that opposes the first magnetic field part, which is on the outer peripheral surface of the rotor, and is provided with a coil for generating a first stator magnetic field; a second stator that opposes the second magnetic field part, which is on the inner peripheral surface of the rotor, and is provided with a coil for generating a second stator magnetic field; and a case that fixes the first stator and second stator and surrounds the rotor. The rotating electric machine has a control unit provided with: a power supply device that supplies power to the coil of the first stator or the second stator so as to drive the rotation of the rotor; and a power collection device for drawing out the induced current generated in the other coil by the rotation of the driven rotor. At least the coil of the stator on the power supply side is formed from a superconductor, and the current supplied to this superconductor coil is made to be greater than the induced current generated by the coil of the other stator.
