Abstract: An interior permanent magnet synchronous motor including a stator including a plurality of teeth, and coils wound around the plurality of teeth; and a rotor configured to be rotatable in a hollow region of the stator. The rotor includes a plurality of permanent magnets in the rotor, and a slit which is arranged within a polar arc angle τ (T=360°/P, where P represents a number of poles of the rotor) and toward a lead side of the polar arc angle τ, and arranged to be inclined in an opposite direction of a rotation direction of the rotor.

Abstract: A consequent pole type interior permanent magnet synchronous motor includes a stator; a rotor rotatable inside the stator; a plurality of permanent magnets inside the rotor; and a plurality of slits formed along a radial direction of the rotor such that the plurality of slits are each between a respective two adjacent permanent magnets among the plurality of permanent magnets. The number of a plurality of consequent poles formed in the rotor by the plurality of permanent magnets is smaller than the number of the plurality of permanent magnets.
