Document Type and Number:
Japanese Patent JP5684529
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a consequent pole type motor which suppresses axial magnetic flux leakage and prevents magnets from falling in the axial direction.SOLUTION: A motor comprises: a motor case 1; and a rotor 3 disposed at an inner side of the motor case 1 and formed by fixing a rotor core 12, which has pseudo-magnetic poles disposed alternately with magnets 13 having one magnetic pole in a circumferential direction, to a rotation shaft 11. The motor is formed by a nonmagnetic material and includes a fixing part 14a disposed between the rotor core 12 and the rotation shaft 11 and fixing the rotor core 12 to the rotation shaft 11 so as to integrally rotate, and a covering fixture member 14 having covering parts 14b and 14c which respectively cover at least parts of axial end surfaces of the magnets 13.
