Background technology
According to the difference of magnet steel (i.e. rare-earth permanent magnet) position on rotor, rotor of synchronous motor with rare-earth permanent magnet magnetic structure generally can be divided into three kinds:
1. surface-type rotor magnetic circuit structural
The magnet steel of this structure is usually in tile shape; and be positioned on the outer surface of rotor core; magnet steel provides the direction of magnetic flux for radial; and generally only overlap the non-magnetic cylinder that shields between magnet steel outer surface and stator core inner circle or wrap on magnet steel surface using without latitude glass tape as protective layer; thus the alinco assembled of this structure electric machine is simple, but fixing and protection comparatively difficulty.
2. built-in rotor magnetic structure
The magnet steel of this class formation is positioned at internal rotor, has the pole shoe that ferromagnetic material (cold rolling silicon steel sheet) is made between magnet steel outer surface and stator core inner circle.By the correlation of the magnet steel direction of magnetization and rotor direction of rotation, built-in rotor magnetic structure can be divided into again radial, tangential and hybrid three kinds, and rotor magnetic circuit structural is relatively complicated, and the embedding difficulty of magnet steel also can correspondingly increase.
3. claw-pole rotor magnetic structure
Claw-pole rotor magnetic structure is made up of two band ring flanges of pawl and the magnet steel of an annular usually.Because circular magnetic steel is directly enclosed within non magnetic rotating shaft, so the alinco assembled of this rotor magnetic circuit structural is comparatively simple.
From above-mentioned three kinds of magnetic structures, can see that rare-earth permanent magnet motor built-in rotor magnetic structure is the most complicated.Because ferromagnetic material around the magnet steel groove of this rotor magnetic circuit structural is to the repulsive force between the attraction of magnet steel and adjacent magnet steel, make the embedding of magnet steel very difficult; For the high motor more than 250 in center, if directly adopt hand assembled and do not use suitable auxiliary mould, not only the labour intensity of operator is large, assembling speed is slow, production efficiency is low, and very easily causes fragmentation or the damage of magnet steel.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of simple to operate, rotor of synchronous motor with rare-earth permanent magnet magnet steel flush mounting that efficiency is high.
For solving the problem, the technical solution adopted in the utility model is: rotor of synchronous motor with rare-earth permanent magnet magnet steel flush mounting, comprise the rotating shaft being arranged on rotor core center, the bottom of the magnet steel groove of rotor core is provided with rotor end holding plate, and the top of described rotating shaft is provided with air pump, and the piston rod of air pump is connected with rotating shaft, the pump housing of air pump is connected with positioning disk, positioning disk is connected with interlock push rod, interlock push rod is vertically arranged, and the lower end of the push rod that links is stretched in magnet steel groove.
Preferably, the upper surface of described rotor core is provided with fairlead, is provided with pilot hole in fairlead, pilot hole is corresponding with magnet steel groove.Described interlock push rod inserts in magnet steel groove through after the pilot hole of fairlead.
Preferably, described air pump is provided with reversal valve, reversal valve is connected with the air pressure valve of air pump by tracheae.
The beneficial effects of the utility model are:
1. owing to only needing hand control reversal valve, interlock push rod and pushed by magnet steel in the magnet steel groove of rotor core rapidly, embeds iron core by force by magnet steel after manually beaing magnet steel, simple to operately saves time, improve the assembling speed of magnet steel and the production efficiency of product, alleviate the labour intensity of operator.
2. the embedding of magnet steel adopts interlock push rod automatically to be pushed by magnet steel in the magnet steel groove of rotor core by air pump air pressure, the stressed magnetic steel inequality caused due to human factor when avoiding manual operation causes the broken or damage of magnet steel, reduce the scrappage of magnet steel, save the stock utilization of magnet steel.
