Study on Improvement of Centrifugal Fan in High-Voltage Motor
摘要
Abstract
The wind wear accounted for a large proportion in the high voltage motor loss. Due to the cooling effect, in addition to the axial flow fan used in the double-pole motor, the centrifugal fan is generally used in the high voltage motor of the four poles and above. The efficiency of ordinary radial centrifugal fan is lower, because there is a large eddy current between blades, this is not conducive to improving the efficiency of the motor. Although the backward centrifugal fan has a higher efficiency, however, the fan isonly suitable for unidirectional rotation, and is not conducive to the universal of the motor. So it is necessary to design a fan with a higher efficiency and a different rotating direction. This paper presents a method for improving the ordinary radial fan of high voltage motor, which can effectively reduce the eddy current between blades, reduce the mechanical loss of the motor, improve motor efficiency.关键词
