Abstract

An electric motor includes a rotor including a first rotor end and a second rotor end, and a stator including a first stator end and a second stator end. The first rotor end is located apart from the first stator end toward the first side. The second rotor end is located apart from the second stator end toward the first side. The relationship between the distances D1 and D2 satisfies D1>D2≥0, where D1 is a distance from a permanent magnet to a first end plate, and D2 is a distance from the permanent magnet to a second end plate. The thickness of each of a plurality of electrical steel sheets is not less than 0.1 mm and not more than 0.25 mm.
