Abstract: A cleaner including a suction head; a main body; and a motor to form a suction airflow from the suction head to the main body. The motor includes a stator; a rotor; and an impeller coupled to the rotor and configured to generate an airflow by being rotated. The motor includes a housing that includes a base portion including a receiving space provided to accommodate the rotor and the stator; and a cover portion including a through-hole through which the rotor passes, the cover portion provided to cover the impeller. The base portion includes a bearing hole formed in an upper portion of the base portion to install a bearing provided to support the rotor; and a stator insertion hole formed to be open on a lateral side of the base portion to allow the stator to be inserted into the receiving space.

Abstract: A motor assembly has a motor having a rotor and a stator. An impeller is connected to a rotary shaft of the rotor and a housing is disposed between the impeller and the motor and surrounding an upper side of the motor. A diffuser discharges air, which is suctioned by the impeller, along an outer surface of the housing. A heat dissipation cover covers an outer surface of the motor. The heat dissipation cover includes an inner cover spaced apart from the outer surface of the motor and forming an inside-cover flow channel that air flows through and an outer cover having a diameter greater than that of the inner cover and forming an outside-cover flow channel through which air flows along the outer surface thereof.

Abstract: A brushless direct current (BLDC) motor includes a rotor having a cylindrical permanent magnet to which a shaft is centrally coupled, and supported to rotate on the shaft. An annular stator surrounds the rotor and includes a plurality of teeth and a wound coil to generate an electromagnetic field. The permanent magnet includes a stress reducing portion, which is provided at opposite end portions thereof, and which has a shape having a mass or a volume which is smaller than a mass or a volume per unit length in an axial direction of a portion of the permanent magnet other than the opposite end portions, to reduce centrifugal stress caused by spinning of the rotor.
