IN-WHEEL MOTOR

An in-wheel motor, comprising: a rotor () of a surface permanent magnet type, wherein a plurality of permanent magnets () are fixed along an inner circumferential surface of the rotor; wedge-shaped protrusions () for fixing the permanent magnets () on the rotor (); and a stator () disposed inside the rotor (), wherein teeth () and slots () are alternately formed on an outer circumferential portion of the stator; wherein the number of the permanent magnets () is 32, and the number of the slots is 24; wherein each of the permanent magnets () has chamfers () on each of the ends so that a magnetic flux cannot concentrate, and is convex toward the stator (), in a cross-section perpendicular to a rotary axis of the rotor ().
