Abstract:
An electric motor includes: a rotary shaft member rotating about an axis; a rotor including a rotor core and a magnet, the rotor core being provided on the rotary shaft member, the magnet being provided on the rotor core; and a stator including a stator core and a stator coil, the stator core having a plurality of slots formed in a circumferential direction, the stator core being disposed at an interval in a radial direction that is a direction orthogonal to an axial direction of the rotary shaft member with respect to the rotor core, the stator coil being inserted into the plurality of slots and wound around the stator core. Further, the stator coil includes a first conductor and a second conductor having a conductivity greater than a conductivity of the first conductor, and the second conductor is disposed in the slots.
