A brushless DC motor including a rotor, a magnet provided to the rotor, a pair of bearings to rotatably support the rotor, a stator assembly that at least partly surrounds the rotor and magnet thereof and adapted to control movement of the rotor, and a bearing tube having an exterior surface and an interior surface that defines a tube interior. The stator assembly is provided along the exterior surface of the tube and the bearings are provided along the interior surface of the tube to support the rotor and magnet 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.
