Motor

A motor comprising:

• a rotor rotatable about a central axis extending in an axial direction;
• a stator including a stator core of a magnetic body in which a coil portion is located;
• a bracket including a stator holder in a tubular shape extending in the axial direction and surrounding the central axis, the stator holder holding the stator core;
• and
• a heat dissipation portion extending in one axial direction from the coil portion, being separate from the bracket, and held by the stator holder;
• wherein
• the heat dissipation portion includes:
• an annular portion that has an annular shape surrounding the stator holder and is located on a radially outer surface of the stator holder;
• and
• an extension extending radially outward from the annular portion;
• the extension includes a plurality of extensions arranged side by side in a circumferential direction;
• the bracket further includes an attachment portion to attach the motor to an external predetermined portion;
• and
• the extension extends in another axial direction from the attachment portion, and between attachment portions including the attachment portion and being adjacent to each other in the circumferential direction as viewed from the axial direction.
