WIPO Patent Application WO/2016/184406
Kind Code:
A1
Abstract:
An ultra-high speed motor, comprising a motor housing (1), a rotor (2), a stator (3), two radial bearings (4), a thrust bearing (5), an inner shaft (6) and an outer shaft (7), the radial bearings being groove-type dynamic pressure gas radial bearings, the thrust bearing being a mixed-type dynamic pressure gas thrust bearing, the rotor being sleeved at a central portion of the inner shaft, the two radial bearings being respectively sleeved on the outer shaft located at left and right ends of the rotor, the thrust bearing being sleeved on the outer shaft at the right end, and being located on an outer end side of a right end radial bearing (4b). The present structure implements an ultra-high speed stable operation in an air state, and with regard to identical power requirements, enables the size of the motor to be significantly reduced for miniaturisation.
