Structure of the thrust magnetic bearing in a magnetic bearing type rotary electric machine

摘要

(57) [summary] [purpose] Surasutokara - the left side of the thrust bearing Yo remain attached to the rotor shaft - to be able to remove a clause from the rotor shaft. [Configuration] in the magnetic bearing type rotary electric machine, the left side of the thrust bearing Yo - Surasutokara that constitute a clause - the so as to form directly to the rotor shaft, the left side of the thrust bearing Yo - clause Outward Yo to embracing the coil - click portion and this outer Yo - two split has been inwardly Yo, which is slidably disposed on the inner periphery of the clock part - to the rotor shaft together constituted by clock part The mounted for decomposing against, whereas, the left side of the thrust bearing Yo - providing a stepped portion on the rotor shaft so as to form a space of a length retrieve clock part - on the left side of the clock said inner Yo It was constructed as. In this case, the inner Yo - is provided with projections on the outer periphery of one of the clock portion, the notch portion for guiding the protrusion in the circumferential direction said outer Yo - provided on the inner peripheral side of the clock part, in each Hoyo - a clock portion as the predetermined angle rotation along the cutout portion of the protrusion, it may be configured to be disengaged from the rotor axis.
