Abstract: Disclosed is an IPM motor that detects an accurate position of a rotor. The IPM motor includes a stator, a hub, a plurality of spokes extending outward in a radial direction from the hub, a plurality of slots defined between the spokes, a rotor rotatably installed in the stator, wherein the rotor includes a plurality of permanent magnets respectively arranged in the slots, a sensor disposed adjacent to the rotor, wherein the sensor is configured to detect a position of each permanent magnet, and a cover disposed on the rotor to cover the rotor, wherein the cover is constructed to guide magnetic flux of each permanent magnet to the sensor at a specific point of the slot of the rotor.
