Motor, blower, and refrigerator

A motor comprising:

• a bobbin having an insertion hole having a first opening end and a second opening end positioned on a side opposite to the first opening end along an extending direction of the bobbin, a first flange disposed at the first opening end, a first exposed portion protruding from the first flange in the extending direction of the bobbin, a second flange disposed at the second opening end and a second exposed portion protruding from the second flange in the extending direction of the bobbin;
• a coil wound around the bobbin;
• a stator core having an excitation part that is inserted into the insertion hole;
• a rotor disposed rotatably with respect to the stator core;
• and
• a resin mold covering the bobbin, the coil, and the stator core, wherein:
• the resin mold covers the first flange and the second flange,
• the first exposed portion and the second exposed portion are formed around whole circumferences of an edge portion of the first opening of the first insertion hole and the second opening of the second insertion hole, respectively,
• the first exposed portion of the bobbin has a first exposed surface that is exposed from the resin mold formed on the first opening end and a second exposed surface that is exposed from the resin mold formed on the second opening end,
• the first exposed portion is positioned between the stator core and the resin mold, the first exposed surface being disposed partially around the first opening end of the insertion hole, and
• the second exposed portion is positioned between the stator core and the resin mold, the second exposed surface being disposed partially around the second opening end of the insertion hole.
