Abstract
The utility model relates to a positioning magnetic steel embedding tool with a groove and uses a magnetic steel embedding tool that is provided with the groove and can function in positioning, and an embedding method. The magnetic steel embedding tool is applicable to an asynchronous starting and synchronous running three-phase rare earth permanent magnet synchronous motor, as well as to all rare earth permanent magnet synchronous motors of built-in type rotor structure. The embedding tool comprises a parallel connection type magnetic circuit structure, a series connection magnetic circuit structure and a mixed type magnetic circuit structure and consists of a guide block and a push rod. The guide block is made of steel, and a gap between the inner chamber wall of the guide block and the magnetic steel is identical with a second gap of the rare earth permanent magnet synchronous motor. A rare earth permanent magnet steel embedding method adopting the magnetic steel embedding tool includes the following steps: firstly placing a magnet with accurate polarity in the inner chamber of the steel guide block of the embedding tool, aligning the port of the inner chamber of the steel guide block where the magnetic steel is arranged with the port of the magnetic steel groove of a permanent magnet synchronous motor rotor, then softly pushing the wooden push rod and smoothly, exactly inserting the magnetic steel in the magnetic steel groove.
Description
Technical field
The utility model relates to a kind of magnet steel intercalation instrument that the location of groove is arranged, use has groove, the magnet steel intercalation instrument that can locate, be applicable to asynchronous starting, the run-in synchronism three-phase rare-earth permanent-magnet synchronous motor, be applicable to the rare-earth permanent-magnet synchronous motor of all built-in rotor structures simultaneously, comprise parallel magnetic structure, tandem magnetic structure and hybrid magnetic structure.
Background technology
Rotor magnetic circuit structural commonly used at present roughly has three kinds:
1, parallel magnetic structure: in parallel magnetic structure, the magnetomotive force that the permanent magnet parallel connection of adjacent two magnetic poles provides every utmost point permanent magnet to produce is used to provide on the external magnetic circuit magnetic pressure of a pair of utmost point to fall, (a) the non-magnetic conductive axis of Cai Yonging (b) then adopts air groove every magnetic every magnetic.Parallel magnetic structure is generally used for the many occasions of number of poles.
2, tandem magnetic structure: tandem magnetic structure, the series connection of the permanent magnet of two magnetic poles provide on the external magnetic circuit magnetic pressure of a pair of utmost point to fall, and every utmost point magnetic flux is provided by the permanent magnet of a magnetic pole.Its advantage is that rotating shaft does not need to adopt non-magnet material, and every utmost point permanent magnet is formed letter U, V, W shape structure respectively, and their advantage is to place more permanent magnet, and every utmost point magnetic flux is big.
3, hybrid magnetic structure: hybrid magnetic structure develops from the tandem magnetic structure and forms, and tangential magnetized two permanent magnets in the adjacent pole are just become hybrid magnetic structure also together.
From above-mentioned three kinds of magnetic structures, the structure that can see the rare-earth permanent-magnet synchronous motor rotor is complicated, the magnet steel that each groove is laid is not only piece, but polylith, the workload of placing magnet steel is big, in addition, more dangerous is, when two or more magnet steel are collected in a groove or a time-out, their upsets are suddenly also jumped, then eyes and human body are produced dangerously, and the polarity of magnet steel must be laid correctly by figure in the groove, as long as magnet steel overturns suddenly and when not realized, to lead to errors one, will influence two blocks of adjacent magnet steel, the inequality that causes the magnetic pressure of the motor rotor utmost point and the utmost point to fall influences the performance of motor.
Summary of the invention
The utility model purpose is to provide a kind of magnet steel intercalation instrument that the location of groove is arranged at above-mentioned weak point, be to use a kind of groove, the magnet steel intercalation instrument that can locate, magnet steel location, the back intercalation earlier of having magnetized with magnetizing, make rare-earth permanent-magnet synchronous motor rotor intercalation magnet steel correctly reliable, it is orderly that polarity mistake and high efficiency do not take place.
A kind of magnet steel intercalation instrument that the location of groove arranged is to take following scheme to realize:
A kind of magnet steel intercalation instrument of the location by groove is made up of guide block and distance rod, and described guide block is made of steel, and guide block has inner chamber, and inner chamber is through high-precision processing, and precision reaches
Distance rod adopts hardwood to make smooth surface.Gap between the internal chamber wall of guide block and the magnet steel is identical with second gap of rare-earth permanent-magnet synchronous motor.According to the rare-earth permanent-magnet synchronous motor of different electromagnetism specifications, adopt the magnet steel of different size, will make the intercalation instrument of different size thus, the present invention is the magnet steel intercalation instrument of gang's different size.
A kind of thulium permanent magnet intercalation method that adopts magnet steel intercalation instrument: the magnet that will firmly believe polarity is earlier put into the inner chamber of the steel guide block of intercalation instrument, accent aligns with the notch of permanent-magnet synchronous motor rotor magnet steel groove in the steel guide block of magnet steel with laying, soften then and promote wooden push rod slowly, magnet steel successfully, is correctly inserted the magnet steel groove, magnet steel upset suddenly and leap do not take place and injure eyes and human body.
A kind of magnet steel intercalation instrument that the location of groove is arranged, because the intercalation instrument is made up of the guide block of steel and the push rod of hardwood system, the guide block inner chamber of steel is through high-precision processing, gap between magnet steel and the internal chamber wall is identical with second gap of rare-earth permanent-magnet synchronous motor, it play the guiding role to magnet steel, make magnet steel under the effect of push rod thrust, in steel guide block inner chamber, slide, enter the magnet steel groove of rotor smoothly, magnet steel can not take place to overturn suddenly, guaranteed magnet steel polarity intercalation correctness, because magnet steel makes steel guide block defendant magnetization, steel guide block magnetic aspect and magnet steel be short circuit together, gentle to push rare-earth permanent-magnet synchronous motor rotor magnetic steel groove very well, laborsaving slowly at steel guide block inner chamber to make magnet steel.
A kind of magnet steel intercalation instrument that the location of groove is arranged is to use a kind of groove, the magnet steel intercalation instrument that can locate, magnet steel location, the back intercalation earlier that the defendant of magnetizing has been magnetized, make rare-earth permanent-magnet synchronous motor rotor intercalation magnet steel correctly reliable, the polarity mistake does not take place, higher intercalation speed is arranged again.
