ロータ及びモータ
Document Type and Number:
Japanese Patent JP5848097
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotor that can further reduce leakage flux stably.SOLUTION: A rotor 11 includes: first and second rotor cores 21 and 22 in which a plurality of first and second claw-shaped magnetic poles 21b and 22b are respectively formed in outer peripheral parts of first and second core bases 21a so as to protrude outward in a radial direction and extend in an axial direction; an annular magnet that is disposed between the axial directions of the first and second core bases 21a, and allows the first claw-shaped magnetic pole 21b and the second claw-shaped magnetic pole 22b to function as different magnetic poles; first and second back auxiliary magnets 24 and 25 that are disposed inside in the radial directions of the first and second claw-shaped magnetic poles 21b and 22b, and are magnetized in the radial direction; and first and second interpole magnets 26 and 27 that are disposed between circumferential directions of the first and second claw-shaped magnetic poles 21b and 22b, and are magnetized in the circumferential direction. The first and second claw-shaped magnetic poles 21b and 22b are provided with an engagement part engaged with the first and second interpole magnets 26 and 27 in the radial direction (radial inside surfaces 21f and 22f in circumferentially extended parts 21e and 22e).
