Abstract

An electric motor includes a stator including four split cores, and a rotor having four magnetic poles. Each of the split cores includes a yoke and a tooth. An angle θ1 [degree] formed by a side surface of the tooth and a side surface of the yoke on an inner side in a radial direction of the stator satisfies 90 degrees ≤θ1<180 degrees.
