Abstract
An electric motor includes a stator and a rotor including a permanent magnet and an electromagnetic steel sheet. The electromagnetic steel sheet includes a magnet insertion hole, a first outer peripheral surface including an inter-pole part of the rotor, a second outer peripheral surface including a magnetic pole center part of the rotor, a first slit elongated in a circumferential direction of the rotor, and a first portion formed between the first slit and the magnet insertion hole. A distance from the first outer peripheral surface to the stator is larger than a distance from the second outer peripheral surface to the stator. The electric motor satisfies θa<θb, where θa is a first angle formed by a first line and a second line and θb is a second angle formed by a third line and the second line.
