摘要: The present invention provides a method and apparatus for efficiently cooling a motor. Three components may be used to provide forced air through a motor and a motor bearing. An air guide plate may direct air in and out of a motor and move air through a bearing seal, a shaft, and the motor. The air guide plate also may shield the bearing from heat. A series of holes, with every other hole an inlet hole or an outlet hole, within the motor housing may be arranged in a common radial plane. The incoming air does not mix with the outgoing air. A series of fins on a rotor may move air in and out of the holes within the motor housing.

摘要: The present invention provides a method and apparatus for varying the high flow and low pressure operating range of a centrifugal blower. Centrifugal blowers are designed and rated for a certain capacity at a certain speed. The present invention provides an apparatus for varying, regulating, or adjusting an inlet capacity of a centrifugal blower. Without the need to redesign or change any blower components, the blower operating range may be changed without affecting blower efficiency. No aerodynamic performance is lost at low flow conditions.

摘要: The present invention provides a method and apparatus for balancing the pressure across a front bearing in a compressor housing. The present invention may protect the bearing from lubricant migration by eliminating pressure differentials across the bearing. When a blower or fan is running, the bearing experiences the same pressure differential that is across the blower. Unless this pressure is balanced, lubricant may migrate from the bearing very quickly. The present invention may provide a pressure balance and sealing across the front bearing of a blower or fan. A plurality of grooves on the face of a compressor impeller and a plurality of grooves on a compressor shaft surface restrict the gas flow to balance pressure across a bearing. Alternatively, a labyrinth seal may cooperate with a plurality of grooves on the face of a compressor impeller to balance pressure across the bearing.
