Abstract
A motor including a stator, and a rotor adapted to rotate, wherein the stator includes a stator body, a plurality of teeth protruding from the stator body toward the rotor, and at least one stator magnetic barrier provided to each of the teeth to interrupt magnetic flux. A magnetic field produced in a direction parallel to the outer circumferential surface of the rotor is attenuated, and therefore demagnetization of permanent magnets included in the rotor may be prevented.
