    摘要： A brushless DC motor (10) including a rotor (14), a magnet (16) provided to the rotor (14), a pair of bearings (20) to rotatably support the rotor (14), a stator assembly (18) that at least partly surrounds the rotor (14) and magnet (16) thereof and adapted to control movement of the rotor (14), and a bearing tube (22) having an exterior surface (42) and an interior surface (48) that defines a tube interior. The stator assembly (18) is provided along the exterior surface (42) of the tube (22) and the bearings (20) are provided along the interior surface (48) of the tube (22) to support the rotor (14) and magnet (16) within the tube interior. The motor has sample application for use in PAP devices for delivery of positive airway pressure therapy for users or patients.

    摘要： The present invention relates to a blower comprising an electric motor having a shaft, said shaft defines a shaft axis; a housing having a housing inlet and a housing outlet between which is defined a flow path for gas; the housing outlet is structured to direct gas exiting the blower in a substantially axial first direction; the motor has a first side proximal said housing inlet, and a second side distal said housing inlet; a first impeller having a plurality of blades adapted to accelerate gas tangentially and to direct it radially outward and being attached to the shaft on the first side of the motor; a stationary portion including: a gas flow path defined between the motor external wall and a wall of the stationary portion, said flow path being of sufficient width to allow a flow of gas therethrough without introducing excessive pressure drop, said flow path directing gas to flow in a generally axial direction from the first side of the motor to the second side of the motor; a first stationary vane structure located downstream of the first impeller, the first stationary vane structure adapted to direct gas exiting the first impeller from flowing in a substantially tangential direction to flowing in both a radial and axial direction; and a shield constructed and arranged to provide a barrier between the first stationary vane structure and the blades of the first impeller to isolate leading edges of the first stationary vane structure from an impeller blade pressure pulse.
