The magnetic bearing is still in the research and development stage, its application is mostly experimental, not mass production, nor commercialization.
A. The application of machine tools in the machine tool spindle, and is on probation.double row angular bearing
(1) precision machine tool spindle
France S2M company manufacturing precision spindle with five degrees of freedom to control the magnetic bearing, radial bearing dn value 4X106mm · r / min, the journal line
speed of 200m / s, thrust bearings, dn value 8X106mm · r / min, thrust journal line speed of 400m / s.ball roller bearing
(2) ultra-precision lens lathe
The France S2M by active magnetic bearing ultra-precision lens lathe spindle speed 2000r/min, power lkW, processing accuracy 0.05ttm.precision ball bearing
Two. Precision instruments
British National Physical Laboratory has developed a maglev rail measuring instrument automatically distinguish in lkHz the band, supporting stiffness for 175N/gm resolution of
0.1nm.
3. Pumps in the application
(1) blood pump
University of Tokyo, Japan, in collaboration with NTN Corporation developed magnetic bearing pump blood. Spindle by the 5-DOF active control of magnetic bearing import radial
bearing load capacity of 18N export bearing radial load capacity of 22N, the carrying capacity of thrust bearing is 9.2N.
(2) circulating pump France SEP using the S2M active magnetic bearing research and development of rocket engines with liquid oxygen, liquid hydrogen circulation pump.
