Kind Code:
A1
Abstract:
A motor according to the present invention includes: a rotor core that is annular and centered on an axial line; a rotor that has a permanent magnet attached to the rotor core; a core back that surrounds the rotor from an outer side in a radial direction centered on the axial line; teeth that extend from the core back toward the rotor; a stator core that has slots adjacent to the teeth in a circumferential direction centered on the axial line; insulating portions attached to the teeth; and a stator that has a conductor made of aluminum and that has windings wound on the teeth with the insulating portions interposed therebetween. A rotor core radius Dr, a stator core radius Ds, and a slot area S satisfy 25 mm ≤ Dr ≤ 30 mm, 0.47 ≤ Dr/Ds ≤ 0.56, and 0.089 ≤ S/Dr2 ≤ 0.224.
