A kind of permanent magnet composite type permanent-magnet steel, dividing plate with magnet steel and permeability magnetic material formation, embed in the box body that constitutes by non-magnet material, magnet steel simultaneously is close to box wall, one side is close to dividing plate, embed filling epoxy resin between dividing plate and box body, and with epoxy resin that magnet steel, dividing plate and box body bonding is in aggregates.Magnet steel can be arbitrary shape and can be combined into by little magnet steel.This structure is specially adapted to the RE permanent magnetic alloy of high magnetic characteristics, compares with original employing monoblock magnet steel and reduces cost 3/4, easily processing, improve machining accuracy, be used on the stator and rotor of AC and DC motor and use as magnetic pole, its magnetic property can improve 1/3, also can use on light fixture.
Description
The present invention relates to a kind of permanent magnet composite type permanent-magnet steel, be mainly used in the AC and DC motor and make stator or rotor magnetic pole usefulness.
Progress into huge numbers of families owing to modern household appliances in recent years, the development of household appliances, increasing to the demand of electrical micro-machine, small machine, and these electrical micro-machines have much all adopted permanent magnet simple in structure, easy to use.And the general used permanent magnet of electrical micro-machine, mostly be the ring-like or watt type of monoblock, the permanent magnet of this kind en-block construction, the magnetic property in centre position is low, and it is inhomogeneous to magnetize, rotating speed of motor and power have been influenced, adopt RE permanent magnetic alloy in recent years, magnetic property is improved greatly, can improve the power of motor, but cost improves, and processing charges also improves.
The object of the present invention is to provide a kind of combined permanent magnet steel, can replace the magnet steel of original en-block construction to be used for making magnetic pole usefulness on the stator of AC and DC motor or the rotor, and can improve machining accuracy, improve magnetic property, reduce cost.
The present invention is achieved in that with permanent-magnet steel with by the dividing plate that permeability magnetic material constitutes and is placed in the box body that is made of non-magnet material, permanent-magnet steel simultaneously is close to box body, one side is close to dividing plate, between dividing plate and box body, fill filling epoxy resin, and each magnet steel and box body are bonded to holistic magnetic pole with epoxy resin, select different magnetic pole number of elements and pole form for use according to the needs of motor.

Below in conjunction with accompanying drawing embodiments of the invention are further described:
Box body (1) is a watt shape, and box body (8) is an annular, and box body (9) is circle or polygon, and one side is an opening, is made by non-magnet material aluminium skin, copper sheet.
Dividing plate (2), (7), (10) shape and box body (1) (8) (9) shape of being put into are complementary, and are respectively a watt shape, annular, circle, make with the blunt iron of permeability magnetic material, strengthen magnetic field intensity, and magnetic field is evenly distributed.
Magnet steel (3), (3) ' cross section are strip, and magnet steel (6), (11) cross section are circular, and the magnet steel cross section can be other Any shape, and material can be ferrite, aluminium nickel cobalt, rare-earth permanent magnet (Nd-Fe-B magnetic pole) etc.
With 4 blocks of magnet steel (3) (also can adopt the odd number magnet steel), dividing plate (2) is put in the box body (1), magnet steel (3) one side is close to box body (1) inner round wall, make full use of Surface field, magnet steel (3) another side is close to dividing plate (2), put filler (4) epoxy resin between the cylindrical wall of dividing plate (2) and box body (1), and magnet steel (3) is sticked on the combined permanent magnet steel that has just constituted an integral body in the box body, can be used as a magnetic pole and use with epoxy resin.Shown in Fig. 1-2, if the magnetic pole of this structure is used on 2 utmost point motors, just with 2 combined permanent magnet steels, be fixed on the two ends of casing respectively with binding agent, just be the magnetic pole of the stator (also can adopt Spring Clip to be fixed on the casing) of 2 utmost point motors, by that analogy, determine by rating of electric machine demand.Also available 4 little magnet steel (5) are formed a magnet steel (3) ' use, shown in figure (4).
Also can adopt structure shown in Fig. 5,6, specifically not describe in detail by the dress method is same as described above, this kind structure is mainly used in micro ceiling fan, and the circular ring type magnetic pole that this is whole is fixed on binding agent on the casing of motor and uses as stator (external rotor) during use.
If even number or odd number magnet steel (3) are fixed in the box body (1), and make magnet steel (3) one side be close to box body (1) cylindrical wall, one side is close to dividing plate (2), put filler (4) concrete grammar and above-mentioned between dividing plate (2) and box body (1) inner round wall with not repeating, be fixed in the rotating shaft as the rotor magnetic pole with this magnetic pole bonding or with Spring Clip, magnet steel (11) is placed in the box body (9), above tight lid dividing plate (10), and the polarity of magnet steel is distributed in the same way, and it is whole with epoxy bond one-tenth, as adopting the magnet of the very thin size of rare earth permanent magnet body and function just can reach very big suction, the combined permanent magnet steel of this kind structure is used to make the ceiling light on the vehicle, automobile-used emergency warning lamps etc. need be than the occasion of strong suction.
This good effect of compared with prior art having of invention: circular ring type, watt type and other any shape that combined permanent magnet steel is specially adapted to the RE permanent magnetic alloy of high magnetic characteristics are compared with original employing monoblock magnet steel and are reduced cost 3/4, and the magnet steel simple shape in the combined permanent magnet steel is easily processed, machining accuracy can improve and reaches ± 0.02mm, be used on the AC and DC motor and use as rotor or magnetic pole of the stator, its magnetic property can improve more than 1/3. This magnet steel is suitable for producing in enormous quantities, is made by specialized factory, and can improve the motor efficiency of assembling, also can use on light fixture.
