Title:
A rotor and a motor
Document Type and Number:
Japanese Patent JP6068048
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a rotor and a motor capable of achieving a structure in which flux leakage through a clearance between a first rotor iron core and a second rotor iron core hardly occurs while suppressing the number of components.SOLUTION: A permanent magnet 6 which makes each of rotor iron cores 4 and 5 function as N-pole and S-pole iron cores is provided between a first rotor iron core 4 and a second rotor iron core 5. The permanent magnet 6 comprises: a magnet body part 16 which fills between an iron core body 8 of the first rotor iron core 4 and an iron core body 11 of the second rotor iron core 5; a plurality of inter-pole magnet parts 17 which fill between claw magnetic poles 9 of the first rotor iron core 4 and claw magnetic poles 12 of the second rotor iron core 5; and back face magnet parts 18 which fill gaps of back faces of each of the claw magnetic poles 9 and 12. Therefore, the permanent magnet 6 in this example is an integrated permanent magnet 6 in which the magnet body part 16, the inter-pole magnet parts 17, and the back face magnet parts 18 are integrally formed.SELECTED DRAWING: Figure 2
