Title:

ROTARY ELECTRIC MACHINE

Document Type and Number:

Japanese Patent JP2018125908

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To prevent an excessive cost increase required for controlling, and to increase an upper limit speed at high-speed rotation according to a rotary electric machine.SOLUTION: A rotary electric machine 10 comprises an inside stator 12 including a three-phase inside coil 19; an outside stator 20 including a three-phase outside coil 25, that is arranged adjacent to an outer side of a radius direction of the inside stator; and one side rotor separately arranged on one side in the radius direction of the inside stator or the outside stator. The one side rotor comprises first magnets arranged at a plurality of positions each in a circumferential direction. One stator of the inside stator and the outside stator is movable in the circumferential direction, and the other stator is immovable in the circumferential direction. The rotary electric machine is configured so as to be able to control an amount of magnetic flux interlinked with the inside coil 19 and the outside coil 25 in the same phase by the one stator being displaced in the circumferential direction with respect to the other stator.SELECTED DRAWING: Figure 2
