ROTARY ELECTRIC MACHINE

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 【課題】回転電機において、制御のために必要なコストの過度な上昇を防止し、かつ、高速回転における上限速度を高くすることである。【解決手段】回転電機１０は、３相の内側コイル１９を含む内側ステータ１２と、内側ステータの半径方向外側に隣り合って配置され、３相の外側コイル２５を含む外側ステータ２０と、内側ステータまたは外側ステータの半径方向一方側に離れて配置された一方側ロータとを含む。一方側ロータは、周方向複数位置に配置された第１磁石を含み、内側ステータ及び外側ステータの一方のステータが周方向に移動可能であり、他方のステータは周方向への移動が不能である。回転電機は、一方のステータが他方のステータに対し周方向にずれることで、同相の内側コイル１９及び外側コイル２５に鎖交する磁束量を制御可能に構成される。【選択図】図２
