Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
In conjunction with Fig. 1 and Fig. 2 it is found that a kind of anti-breakdown rotor, including main body 1, wherein mandrel is provided in main body 1
2, while it being arranged iron core 3 outside mandrel 2, and coil is wrapped on iron core 3.In actual use, if 3 surface of iron core not
If insulation, there is sliding friction between the insulating film meeting and iron core 3 of enameled wire and broken skin, thus punctures, to can cause
Electric shock.
Therefore 3 both ends of iron core are provided with insulating trip 4, and at least one layer of insulating paper 5 is provided between iron core 3 and coil,
To which circumferential at iron core 3 weeks and front and back end is provided with insulant, to completely cut off iron core 3 and coil, and then iron core 3 and line are avoided
Circle contact, to prevent from forming breakdown, and then reduces the risk of electric shock, guarantees the safety of user.
In conjunction with Fig. 1 and Fig. 2 it is found that can advanced optimize, axle sleeve 13 is arranged with outside mandrel 2, and be arranged with outside axle sleeve 13
Insulating trip 4 to completely cut off iron core 3 and mandrel 2, and then avoids iron core 3 and mandrel 2 from contacting, to prevent from forming breakdown, and then subtracts
The risk of low electric shock, guarantees the safety of user.
And axle sleeve 13 herein is component made of BMC rotor molding mass.BMC is a kind of semidry method manufacture glass fibre
The molding intermediate materials for enhancing thermoset articles, by unsaturated polyester resin, lower shrinkage/low-contour additive, initiator, interior de-
Mould agent, mineral filler etc. are pre-mixed into paste, add thickener, colorant etc., the glass fibre with different length, special
It is stirred in material kettle, carries out thickening, ultimately form the intermediary material of bulk, can be used for being molded and being infused
Modeling.And compared with common thermoplastic, the performances such as product heat resistance, insulating properties, elasticity modulus want higher.
As shown in Figure 4, it is known that iron core 3 is provided with several rotating vanes 6, and through slot 7 is offered between rotating vane 6.It insulate simultaneously
Paper 5 is placed in through slot 7, and coil is also wound in through slot 7, so that iron core 3 and coil contact are completely cut off by insulating paper 5, from
And prevent from forming breakdown, and then reduce the risk of electric shock, guarantee the safety of user.
And as shown in Figure 5, it is known that iron core 3 is provided with several iron core regions 14, and each iron core region 14 offers
Centre bore 15 and through slot 7.
It can advanced optimize, iron core 3 is provided at least two iron core regions 14, and the diameter dimension in iron core region 14 is one
Sample or the diameter dimension in iron core region 14 are gradually to successively decrease.In actual use, mandrel 2 is threaded through in centre bore 15,
And under normal circumstances, for consideration easy to process, thus the diameter of centre bore 15 is usually constant, but in order to adapt to more
The demand of more motor and some equipment, thus the mandrel 2 of varying aperture can be generated, thus corresponding generation varying aperture centre bore
15。
Simultaneously in the case where the aperture of centre bore 15 is variation, in order to facilitate processing, thus around the logical of centre bore 15
The opening diameter of slot 7 and position generally require the larger aperture position (i.e. large aperture end) according to centre bore 15 then determining and
Design.Which results in rotor cores at 15 smaller aperture due position of centre bore, and the yoke portion at (i.e. small-bore end) is unable to fully effectively
It utilizes, the resistance of conducting bar is caused to become larger, loss increases, and efficiency reduces, and the effective rate of utilization of material reduces, and electric motor starting difficulty adds
Greatly, the performance of motor cannot be given full play of.
Therefore by the opening diameter size of through slot 7 as the diameter dimension increase of centre bore 15 reduces, so that having
The iron core section of different pore size centre bore has the yoke portion of zone of reasonableness size, substantially effectively utilizes yoke portion material, avoids
Lead to the problem of can only being adapted to the biggish conducting bar of resistance and loss increase, efficiency is brought to reduce since design is unreasonable in,
And then the leakage reactance of conducting bar is increased, to improve electric motor starting torque, reduce the difficulty of electric motor starting.
In conjunction with Fig. 2 and Fig. 3 it is found that being provided at least two layers of insulating paper 5, respectively insulating paper 5 between iron core 3 and coil
Respectively insulating paper 1 and insulating paper 29.Wherein insulating paper 1 is DMD insulating paper, and insulating paper 29 is FDM insulating paper.And
And in order between clear all parts relationship and position, thus all parts are filled with to different patterns in Fig. 3.
DMD, full name polyester film and polyester fibre nonwoven fabric softness composite insulating foil simultaneously are by folder among two layers polyester non-woven fabrics
The three-layer insulated material that one layer of insulation polyester film is combined.And the moulding material of FDM fused glass pellet technology is mainly
Thermoplastic material, generally ABS, PLA, PC, PP, synthetic rubber, PPSF and PEI.In actual use, pass through multilayer
Insulating paper isolation iron core 3 and coil contact, can avoid one layer and broken just to puncture later, and the protection of multilayer, can be when one
After layer has been broken, protected there are also one layer.
As shown in figure 3, insulating paper 29 is placed in through slot 7, and it is set on insulating paper 1；And 29 both ends of insulating paper
Bending forming clamping portion 10, clamping portion 10 are connected to the corner of insulating paper 1.
Insulating paper 1 includes bending part 11 and evener 12 known to simultaneously, and bending part 11 is connected in through slot 7, and smooth
Portion 12 is covered on rotating vane 6, and the clamping portion 10 is connected to the junction of bending part 11 and evener 12.
In actual use, insulating paper 29 is put into through slot 7 first, is then bent into insulating paper 1 curved
Folding part 11 is put into insulating paper 29, while having evener 12 between two bending parts 11, and evener 12 is covered on rotating vane 6.And
And the disengaging of insulating paper 1 is prevented, thus 29 both ends bending forming clamping portion 10 of insulating paper, and clamping portion 10 is connected to bending
Junction between portion 11 and evener 12 to impose on the inside pulling force of insulating paper 1 by insulating paper 29, and then hinders
The disengaging of insulating paper 1.
The specific work process of this programme is as follows:
A kind of anti-breakdown rotor, including main body 1 are wherein provided with mandrel 2, while 2 housing of mandrel in main body 1
If iron core 3, and coil is wrapped on iron core 3.In actual use, if if 3 surface of iron core is on-insulated, enameled wire
Insulating film meeting and iron core 3 between have a sliding friction and broken skin, thus puncture, so that electric shock can be caused.
Therefore 3 both ends of iron core are provided with insulating trip 4, and at least one layer of insulating paper 5 is provided between iron core 3 and coil,
To which circumferential at iron core 3 weeks and front and back end is provided with insulant, to completely cut off iron core 3 and coil, and then iron core 3 and line are avoided
Circle contact, to prevent from forming breakdown, and then reduces the risk of electric shock, guarantees the safety of user.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
