Abstract:
A motor, comprising:a case body having a bottom surface section; a recessed concave section that is located inside the bottom surface section in a radial direction and concaves inwardly in an axial direction at an area opposing an excitation coil provided within the case body; and a bearing retaining section that is formed inside the recessed concave section in the radial direction, wherein at least one part of the bearing retaining section is located more interior in the axial direction than the bottom surface section, wherein the excitation coil is wound around a stator core such that the number of turns of the excitation coil becomes greater toward outside in the radial direction, and wherein the excitation coil wound around the stator core defines an inclined end surface that concaves in the axial direction, and the recessed concave section of the case body has an inclined surface section that inwardly concaves in the axial direction and extends along the inclined end surface of the excitation coil wound around the stator core.
