Abstract

The patent application discloses an electric motor. The motor has a stator (140) and a rotor (170) that rotates about the stator (140). The stator (140) comprises: a stator core (141 ), in which a magnetic flux path is formed; a plurality of teeth (142) projected in radial direction of the stator core (141 ); pole shoes (149), that extend in both circumferential directions on the free end of the teeth; and a cogging torque reduction part (149a) formed on the pole shoe to prevent a drastic change of the magnetic pole, such that cogging torque is minimised.
