Title:
AXIAL GAP MOTOR
Document Type and Number:
Japanese Patent JP2019161760
Kind Code:
A
Abstract:
To provide an axial gap motor the output of which can be increased without involving upsizing.SOLUTION: A circular arc second magnet piece 11c in contact with the inner circumferential surface of each first magnet piece 11b, and a circular arc third magnet piece 11d in contact with the outer circumferential surface are provided in a rotor 11. When an opposing surface side, of the first magnet piece, to a stator is an N pole, the magnetization direction of the second magnet piece is settled such that the inner circumferential surface side of the second magnet piece becomes an N pole, and the magnetization direction of the third magnet piece is settled such that the outer circumferential surface side of the third magnet piece becomes an N pole. When the opposing surface side, of the first magnet piece, to the stator is an S pole, the magnetization direction of the second magnet piece is settled such that the outer circumferential surface side of the second magnet piece becomes an N pole, and the magnetization direction of the third magnet piece is settled such that the inner circumferential surface side of the third magnet piece becomes an N pole. A first annular projection 11e formed of a magnetic body in contact with the inner circumferential surface of the second magnet piece, and a second annular projection 11f formed of a magnetic body in contact with the outer circumferential surface of the third magnet piece are provided on the inner circumferential section and the outer circumferential section of the opposing surface, of a rotor core 11a, to the stator 12.SELECTED DRAWING: Figure 2
