Abstract
An electric motor includes: a rotor including a first rotor core and a second rotor core; and a stator. A minimum distance from the first rotor core to the stator is shorter than a minimum distance from the second rotor core to the stator. A maximum radius of the first rotor core is longer than a maximum radius of the second rotor core. A shape of a first thin-wall part of the first rotor core and a shape of a second thin-wall part of the second rotor core are the same.
