Abstract
A motor includes a stator having a ring type structure and including a plurality of teeth protruding toward an inner surface of the stator and coils wound around the teeth; and a rotor including a core with a plurality of permanent magnets circumferentially magnetized inside the stator around a rotation shaft and a non-magnetic member between the core and the rotation shaft, and the permanent magnet includes a protrusion protruding to the non-magnetic member. An area of the permanent magnet is increased by increasing a length of the permanent magnet so that a magnetic flux can be increased to increase a torque.
