Motor and method of manufacturing motor

A method of manufacturing a motor including a rotor including a shaft extending along a central axis, a stator including a coil and opposing the rotor in a radial direction with a gap provided therebetween, and a busbar positioned at one axial-directional side of the stator, the method comprising:

• holding a conducting wire, which extends from the coil, on the busbar;
• wherein
• the holding includes inserting the conducting wire into a notch provided in a conducting wire-connecting portion of the busbar and caulking the conducting wire-connecting portion in a direction in which the notch is closed;
• an inner circumferential surface of the notch includes a bottom surface opposing an opening side of the notch, a first opposed surface extending from the bottom surface towards the opening, and a second opposed surface extending from the bottom surface towards the opening and opposing the first opposed surface;
• the first opposed surface includes a first region connected to the bottom surface and a second region connected to the first region and extending to the opening side;
• a convex portion protruding towards the second opposed surface is provided on a first boundary portion between the first region and the second region;
• before the caulking, the second region is inclined in a direction in which the second region is spaced away from the second opposed surface, as it extends towards the opening side;
• after the caulking, the conducting wire-connecting portion is in contact with the conducting wire in the bottom surface, the second opposed surface and the first region of the first opposed surface;
• and
• the busbar includes a plurality of the conducting wire-connecting portions, all of opening directions of the notches of the plurality of the conducting wire-connecting portions are directed towards one circumferential-directional side, and in the inserting, the busbar is rotated about the central axis to insert the conducting wire into each of the notches of the plurality of the conducting wire-connecting portions.

A motor, comprising:

• a rotor including a shaft extending along a central axis;
• a stator including a coil and opposing the rotor in a radial direction with a gap provided therebetween;
• and
• a busbar positioned at one axial-directional side of the stator;
• wherein

• a notch into which the conducting wire is inserted is provided in the conducting wire-connecting portion;
• an inner circumferential surface of the notch includes a bottom surface opposing an opening side of the notch, a first opposed surface extending from the bottom surface towards the opening, and a second opposed surface extending from the bottom surface towards the opening and opposing the first opposed surface;
• the first opposed surface includes a first region connected to the bottom surface and a second region connected to the first region and extending to the opening side;
• a first convex portion protruding towards the second opposed surface is provided on a first boundary portion between the first region and the second region;
• the conducting wire-connecting portion is in contact with the conducting wire in the bottom surface, the second opposed surface and the first region of the first opposed surface;
• and
• the bottom surface is provided with a concavity portion defined therein and extending to a side opposite to the opening side.
