Abstract

The invention provides a homopolar type radial magnetic suspension bearing and a manufacturing method thereof, which relate to the technical field of magnetic suspension. The homopolar type radial magnetic suspension bearing disclosed by the invention comprises a first pressing plate, a first laminated piece of the bearing, a plurality of connecting laminated pieces, a second laminated piece of the bearing and a second pressing plate, wherein both sides of the connecting laminated pieces are respectively provided with the first laminated piece of the bearing and the second laminated piece of the bearing, the outer side of the first laminated piece of the bearing is provided with the first pressing plate, the outer side of the second laminated piece of the bearing is provided with the second pressing plate, and the first laminated piece of the bearing and the second laminated piece of the bearing are arranged in a heteropolar type and are respectively arranged in a homopolar type. By the homopolar type radial magnetic suspension bearing and the manufacturing method thereof, which are disclosed by the invention, the aims of high manufacturing accuracy, simple process and low cost are realized.

Description

technical field [0001] The invention relates to the technical field of magnetic suspension. [0002] Background technique [0003] Compared with traditional bearings, magnetic suspension bearings have no contact with the rotor, support low power consumption, and have a long service life; do not need lubrication and sealing, and can be used in special environments such as high and low temperature for a long time; low maintenance costs, easy to actively control, etc., so It is considered to be a revolution in support technology, and it is the only active support device put into practical use at present. [0004] Although it has the incomparable advantages of traditional bearings, magnetic suspension bearings still have eddy current and hysteresis losses, especially in high-power applications (such as aircraft engines, expanders, steam turbines, etc.), eddy currents and hysteresis losses are very large, so it is necessary to use Strong cooling measures, so low-loss magnetic b...
