    摘要： A motor assembly comprises a first end frame, a second end frame including at least one air outlet aperture, an air shroud surrounding a stator between the first end frame and the second end frame, the air shroud cooperating with the stator to form at least one air passage, and cooperating with the first end frame to form at least one air inlet aperture. The motor assembly also comprises a fan mounted on the rotating shaft, the fan operable to generate an air flow of ambient air through the at least one air inlet aperture, the at least one air passage and the at least one air outlet aperture.

    摘要： A turbine pump that permits an impeller to stay compliant with a raceway by the use of a preloaded floating raceway that operates by utilizing fluid floating on both side of the raceway within the pump. Exemplary embodiments of the pump include a mounting frame that is adapted to engage the pump to a drive source; an end frame that is adapted to attach to the mounting frame and includes an inlet section and an outlet section that facilitate fluid flow entering and exiting the pump; a motor shaft enclosed within the mounting frame; a floating raceway that is situated within the end frame and positioned around the distal end of the motor shaft, and includes an inlet passage, an outlet passage and a bypass hole fixed relative to the position of the inlet passage and the outlet passage; a spring located at the top of the floating raceway and at least partially contained within a corresponding cavity located in the end frame that is preloaded to help maintain a desired clearance between the floating raceway and the impeller; and an impeller secured to an distal end of the motor shaft.
