MOTOR AND ELECTRIC VEHICLE
Document Type and Number:
Japanese Patent JP2023127998
Kind Code:
A
Abstract:
To provide a motor and an electric vehicle for improving heat dissipation of a coil portion.SOLUTION: A motor 1 includes a rotor 2 and a stator 3. The rotor 2 is rotatable around a central axis CA extending in an axial direction. The stator 3 has a stator core 31 facing the rotor 2 in a radial direction. The stator core 31 has a core back portion 311 and a tooth portion 312. The core back portion 311 surrounds the central axis CA. The tooth portion 312 extends from the core back portion 311 in the radial direction. The stator 3 further includes a deformable heat dissipating member 33 and a coil portion 34. The heat dissipating member 33 is placed on the outer side of the tooth portion 312 in a direction perpendicular to the radial direction. The coil portion 34 has a conducting wire 341. The conducting wire 341 is placed on the tooth portion 312 via the heat dissipating member 33.SELECTED DRAWING: Figure 1
