MOTOR
Document Type and Number:
Japanese Patent JP2020191749
Kind Code:
A
Abstract:
To provide a motor in which a bearing can be appropriately disposed at an end of a stator.SOLUTION: In a motor 1, an end plate 8 is fixed to an end of a non-output side La of a stator 4, and a bearing 9 is fixed to the end plate 8. When a radially outer end 920 of a flange part 92 protruding from the end plate 8 to an output side Lb comes into contact from the radially inner side with a pole tooth 45 of an outer stator core 44 without being fixed thereto, the bearing 9 is positioned in the radial direction. The pole tooth 45 has: a root part 451 which is protrudingly curved and bent toward the radially inner side; and a tip part 452 which extends from the root part 451 along a motor axial line L. The bearing 9 comes into contact from the radially inner side with a portion, of the tip part 452 of the pole tooth 45, close to the root part 451. Thus, a rotary shaft 30 can be appropriately supported by the bearing 9 because it is less likely that the bearing 9 is fixed in an inclined posture.SELECTED DRAWING: Figure 2
