Abstract:
An electric motor includes: a rotor that has a rotation axis; and a stator that includes an annular yoke portion having the rotation axis as a center, and a plurality of teeth portions which protrude in a radial direction from the yoke portion, in which the stator is configured with split stators including a plurality of split yoke portions which are split in a circumferential direction, and each of the split stators includes an abutting portion on which the adjacent split yoke portions abut each other, on a side close to the rotor, and a welding portion on which the adjacent split yoke portions are welded in a state of being separated from each other, on a side further distant from the rotor than the abutting portion.
