Provided is a high speed and high efficiency IPM (Interior Permanent Magnet) motor and a slim type vacuum inhaling apparatus using the same, which establishes a passage path of introduced air into a path of air-cooling the inside of a stator and a circuit element to thus cool heat that is produced from the IPM motor without a special heat radiator. The IPM motor includes: a stator having a number of tees which are protruded so as to form a number of slots on the inner circumferential wall of a cylindrical body, and a stator coil which is partially wound around the slots; and an IPM type rotor having a rotor core at the central side of which a rotating shaft is mounted, and a number of permanent magnets which are fitted into a number of permanent magnet insertion holes which are formed on the identical circumference of the rotor core, and which is rotated by the stator.
