Claims19
A motor comprising:
- a rotor;
- a stator;
- a circuit board attached to the stator;
- a heat dissipation member disposed on a side of the circuit board opposite to the stator;
- and
- a resin portion covering the stator, the circuit board, and at least a part of the heat dissipation member,
- wherein the heat dissipation member has a first positioning portion having a hole or a concave portion, and
- wherein the resin portion has a second positioning portion having a hole or a concave portion, at a position positioning portion in a direction of a rotation axis of the rotor.
