Title:
MAGNETIC SUSPENSION SPINDLE STRUCTURE OF WIND POWER GENERATOR UNIT
Document Type and Number:
WIPO Patent Application WO/2013/181890
Kind Code:
A1
Abstract:
Disclosed is a magnetic suspension spindle structure of a wind power generator unit, which comprises a spindle (20) and a bearing part (40) of a power generator (10). The spindle (20) is fixedly connected with a first permanent magnet (50). The bearing part (40) is provided with a second permanent magnet (60). Same magnetic poles of the first permanent magnet (50) on the spindle (20) and the second permanent magnet (60) on the bearing part (40) are oppositely and vertically arranged. Repulsive force generated by repulsion of the same magnetic poles of the first permanent magnet (50) and the second permanent magnet (60) can be used for balancing gravity of the spindle (20) and fan blades (30). The magnetic suspension spindle structure reduces the starting wind speed of the wind power generator unit.
