Abstract: A permanent magnet motor and a home appliance including the permanent magnet motor are provided. The permanent magnet motor includes a stator and a rotor rotatable relative to the stator. The rotor includes a rotary shaft, a rotor core fixed to the rotary shaft, a commutator fixed to the rotary shaft and adjacent the rotor core, and a rotor winding wound around poles of the rotor core and electrically connected with the commutator. The stator includes a cylindrical housing, a permanent magnet mounted to an inner surface of the housing, and brushes in sliding contact with the commutator. A ratio of an outer diameter of the rotor core to an outer diameter of the housing is 60% to 85%, and a wire diameter of the rotor winding is 0.12 mm to 0.23 mm. The present invention can provide higher output power without increasing sizes of the motor.

Abstract: A vacuum cleaner has a brush roll which has a housing. A motor is disposed within the housing and has a pulley mounted on a shaft of the motor. A roller is disposed within the housing and has a drive wheel. A belt couples the pulley to the drive wheel, so that the motor can drive the roller. The roller has bristles for sweeping a surface to be cleaned.
