Embodiment
Now by reference to the accompanying drawings, the utility model embodiment is described in detail in detail:
The utility model is realized in the following way, and is illustrated in conjunction with Fig. 2:
Internal rotor without interior magnetic according to claim 1 (5): 1. novel internal rotor without interior magnetic, mainly include: interior magnetic guiding loop (51), high magnetic flux rate 1J22(state label) soft magnetic material is made magnetic level (52), 4 or greater than 4 even numbered poles, every magnetic level (52) is merged into 1 magnetic pole by the high magnetic flux rate 1J22 soft magnetic material of 2-4 same sizes, because 1J22 soft magnetic material Curie temperature has 980 ℃, so can obtain outer magnet rotor (4) outer steel in the media fluid of 350 ℃ to 500 ℃ of high temperature magnetizes, and with the coupling of outer magnet rotor (4) outer steel phase, and soft magnetic material is by 2-4 same sizes and close and form, has very strong poly-magnetic field, because magnetic force is to be distributed in extension, merge the magnetic pole that forms when minute equal volume, magnetic flux is higher.Can get by test, after 1J22 soft magnetic material and 3 merging and 3 blocks of small size 1J22 soft magnetic materials equating of cumulative volume relatively, 3 magnetic flux density that merge the magnetic pole that small size 1J22 soft magnetic material forms are high under identical condition, torque is also large, is not easy to take off mutually with outer magnet rotor to turn.2. the novel internal rotor without interior magnetic (5), shell (53) is installed in outside the high magnetic flux rate soft magnetic material magnetic level (52), since be usefulness be soft magnetic material, can not cause because of the attraction of magnetic in process of production iron filings attraction and when welding the difficult problem that is attracted of electric arc electron beam, shell (53) covering is to be made by austenitic stainless steel, because austenitic stainless steel has magnetic characteristic, so working as internal rotor and outer magnet rotor (4) magnet steel coupling rotation is that leakage field is few, can well weld encapsulation.3. the novel rotor without interior magnetic (5), high magnetic flux rate soft magnetism soft magnetic material magnetic level (52) is installed on the interior magnetic guiding loop (51), and interior magnetic guiding loop (51) is to be made of soft magnetic material, has magnet accumulating cap, improves the efficient of magnetic conduction.4. the novel rotor without interior magnetic (5), the main mistake of support (54) decide the soft magnetism magnetic pole and with the shell encapsulation effect.To have austenitic stainless steel to make because austenitic stainless steel has magnetic characteristic, so when internal rotor be that leakage field is few with outer magnet rotor (4) magnet steel coupling rotation, efficient is high.5. being provided with the waveform jump ring (55) that is connected with the axle interference in the interior axis hole of support ring (54), mainly is that fixed rotating shaft comprises ceramic shaft, carborundum axle etc., takes off when avoiding high temperature to turn.
Described outer magnet rotor (4) includes: the arrangement of being separated by of external rotor matrix (41), N level and S level, number of pole-pairs and internal rotor with respect to even level, each N level or S level form (42) by polylith polymerization outer steel at the same level; Rotating shaft (43); Outer magnetic guiding loop (44), outer magnetic guiding loop (44) is that soft magnetic material consists of.
The utility model structural design is simple, easy to operate, increase work efficiency and reduce the superhigh temperature resistant of cost without the internal rotor magnetic coupling of interior magnetic.
