Zusammenfassung:An electric motor according to an embodiment includes a stator and a rotor. The stator includes an iron core including a cylindrical yoke and nine teeth protruding inwardly of the yoke, an insulating member provided at an end portion in an axial direction of the iron core, three independent windings respectively wound continuously on three different teeth of the nine teeth, three first crimp terminals provided respectively to the three windings, and three second crimp terminals provided respectively to the three windings. Each of the three windings includes a first terminal wire, a second terminal wire, a first intermediate wire between two teeth close to the second terminal wire, and a second intermediate wire between two teeth close to the first terminal wire. The first crimp terminal connects the first terminal wire of the corresponding winding to two points of the first intermediate wire of the winding. The second crimp terminal connects the second terminal wire of the corresponding winding to two points of the second intermediate wire of the winding.
