Description
Technical field
The utility model belongs to magneto, is specifically related to a kind of rotor iron core lamination of Large-power High-Speed magneto.
Background technology
Traditional salient pole synchronous electric machine is the low speed small power motor, the magnet steel that its pole pair is answered directly is adsorbed on yoke, and the fixed form of above-mentioned magnet steel can't be applied on the Large-power High-Speed salient pole synchronous electric machine, rotating shaft is under High Rotation Speed, can produce larger centrifugal force, magnet steel is thrown away, cause security incident, and can cause damage to motor.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rotor iron core lamination of Large-power High-Speed magneto, after the stacked formation iron core of this punching, can be fixed on magnet steel, avoids the rotor high-speed rotation to produce centrifugal force magnet steel is thrown away.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of rotor iron core lamination of large high-power high-speed permanent magnet motor is characterized in that: the outer rim of described core stamping has equally distributed a plurality of protuberance, all has been arranged side by side a plurality of perforation on each protuberance of described core stamping.
Adopt said structure, after the stacked formation rotor core of core stamping, the perforation of same position just forms the magnet steel installing hole that axially runs through, thereby makes magnet steel can be fixed in these magnet steel installing holes.
In embodiment of the present utility model, described each core stamping outer rim has 6 protuberances, has 4 perforation on each protuberance.
The rectangular shapes of centre two perforation on described each protuberance, and the both sides edge of this perforation all be one step-like.
Between the magnet steel that arranges in two perforation of described centre, spacing L1 is 6mm.
The rectangular shapes of sidepiece two perforation on described each protuberance, and the inboard edge of this perforation be one step-like, outside edge be two continuous step-like.
The magnet steel that arranges in described sidepiece two perforation and the spacing L2 of protuberance respective side edge are 10mm.
Adopt technique scheme, the Large-power High-Speed permanent magnet machine rotor that utilizes punching of the present utility model to make has following advantage:
1, have the magnet steel installing hole on the iron core that is stacked to by punching, be used for mounting magnetic steel, can avoid magnet steel to be thrown out of because of the high centrifugal force that rotor produces, and then cause security incident and damage motor, and easy to assembly, and cost is low.
2, be stepped design by the corner of boring a hole, can make between magnet steel and perforation sidepiece, magnet steel and magnet steel, magnet steel and protuberance side and have certain spacing, not only can play and reduce the tensile stress of motor rotor punching sheet under High Rotation Speed, install but also be convenient to magnet steel.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Fig. 1 is the structural representation of rotor iron core lamination of the present utility model.

Embodiment
As shown in Figure 1, rotor iron core lamination of the present utility model, the outer rim of core stamping 5 has equally distributed a plurality of protuberance 6.A plurality of perforation 7 all have been arranged side by side on each protuberance 6 of core stamping 5.In the drawings, core stamping 5 outer rims have 6 protuberances 6, have 4 perforation 7 on each protuberance 6.
Please in conjunction with shown in Figure 3, the centre two rectangular shapes of perforation 7a on described each protuberance 6, and the both sides edge of this perforation 7 all is a step-like a, the width that magnet steel 4 in the inner so is installed need be slightly less than perforation 7a width, being magnet steel 4 both sides exists certain spacing with perforation 7a both sides, can not rub mutually with perforation 7a both sides when so installing, facilitate the installation of magnet steel 4.In addition, spacing L1 between the magnet steel 4 that arranges in middle two perforation 7a is controlled at the 6mm left and right, can plays the effect that reduces the tensile stress that motor rotor punching sheet causes because of centrifugal force when High Rotation Speed.Please in conjunction with shown in Figure 4, the sidepiece two rectangular shapes of perforation 7b on described each protuberance 6, and the inboard edge of this perforation 7b is a step-like a equally, and outside edge is two continuous step-like b.The magnet steel 4 that arranges in described sidepiece two perforation 7b is controlled at 10mm with the spacing L2 of protuberance 6 respective side edge.
As shown in Figure 2, core stamping 5 forms rotor core after stacked and is arranged on armature spindle 1, and the perforation 7 of same position is a magnet steel installing hole 8 that axially runs through after core stamping 5 is stacked, and magnet steel 4 just is located in magnet steel installing hole 8.Magnet steel 4 in each magnet steel installing hole 8 shown in Fig. 2 is a plurality of for what axially be arranged side by side, and the installation length of whole magnet steel 4 and magnet steel installing hole 8 axial lengths are isometric.Again in conjunction with Fig. 3 and shown in Figure 4, in addition, described magnet steel 4 is namely bored a hole with magnet steel installing hole 8() the surrounding gap in the glue layer 9 that is made of the magnet steel glue special also is set, play the effect of buffering and damping in the High Rotation Speed process of rotor, this glue layer 9 is smeared in magnet steel 4 installation processes, also have lubricated effect, be convenient to assembling.
In sum, the Large-power High-Speed permanent magnet machine rotor that utilizes punching of the present utility model to make has following advantage:
1, have the magnet steel installing hole on the iron core that is stacked to by punching, be used for mounting magnetic steel, can avoid magnet steel to be thrown out of because of the high centrifugal force that rotor produces, and then cause security incident and damage motor, and easy to assembly, and cost is low.
2, be stepped design by the corner of boring a hole, can make between magnet steel and perforation sidepiece, magnet steel and magnet steel, magnet steel and protuberance side and have certain spacing, not only can play and reduce the tensile stress of motor rotor punching sheet under High Rotation Speed, install but also be convenient to magnet steel.
