The utility model solves the problems of the technologies described above the technical scheme adopted and simplifies magnetic Circuit Design, applies a kind of process for processing mode being convenient to batch production. The radial magnetic bearing of the utility model design is made up of two parts, i.e. rotor and stator module; Wherein stator module is made up of five assemblies again, is end ring on stator core, location, the lower end ring in location, magnet coil coil, outlet line composition respectively. Its rotor according to requirements and operating mode, selects several pieces thickness to be that the silicon steel plate stacking of 0.15-0.5mm is formed, and shape is annular. Stator core adopt too several pieces thickness be 0.15-0.5mm silicon steel plate stacking form, shape is circular strip tooth, here it is exactly the magnetic pole defined below that tooth-like protuberance divides, for simplifying loop, magnetic field, improving the symmetry of magnetic circuit, reduce leakage field on-the-spot, the pole design of this scheme adopts 8 poles or 16 pole rectangle designs, circumferentially being uniformly distributed, one group or 3 one group forms the loop, magnetic field claimed in pairs on four direction between two. Stator core laminates mode owing to adopting, add in the siliconized plate course of processing, the consistence such as thickness own, parallelism are not fine, it is the stator core of 15mm for thickness, may there is the not parallel amount of 0.5-3mm in its both ends of the surface, and cannot process, cause last setting accuracy not reach design requirements. For addressing this problem, we devise location end ring at stator core two ends, namely locate upper end ring, the lower end ring in location, ensure the parallelism of radial magnetic bearing stator both ends of the surface by processing two end ring, to reach setting accuracy requirement. In addition, for batch production, directly on stator core, coiling efficiency is too low, difficulty is bigger, consistence does not also ensure well, therefore, in this scheme, we have also been devised coil support, coil timbering material can select high-strength insulating paper or fire resistant resin material, the structure of support according to the profile design of magnetic pole, support adopts back font schemes, it is convenient to install and coiling, then directly on support, carries out coiling by winding machine, so both improve winding efficiency, being convenient to batch production, the consistence of coil have also been obtained guarantee simultaneously. In order to simplify and the wiring of specification coil in stator core, avoid employee due to careless and inadvertent wrong outlet line, we have formulated shortest path, clockwise wire laying mode, utilize the coil rack making different colours simultaneously, it is arranged on one to one on corresponding core magnetic pole, ensure that installation order and the exactness of position is installed. After connection completes, in order to improve the heat dispersion of radial magnetic bearing, adopting the epoxy resin of excellent thermal conductivity to be divided by coil portion and carry out embedding, fixing on stator core of coil is also played provide protection by the resin of embedding.
The utility model compared with the existing technology has the following advantages and effect: 1. simplify magnetic Circuit Design, simplifies loop, magnetic field, it is to increase magnetic circuit symmetry, reduces leakage field on-the-spot; 2. by the parallelism of processing two ends environmental protection card radial magnetic bearing stator both ends of the surface, to reach setting accuracy requirement; 3. adopt Back Word type coil support, it is convenient to install and coiling, it is to increase winding efficiency is convenient to produce, and the consistence of coil is ensured simultaneously; 4. adopt the coil rack answered of Color pair and outlet line, in order to distinguish respective function, ensure installation order and the exactness of position is installed, avoid employee in follow-up assembling, mistake to occur due to negligence.
