Description
Technical field
The present invention relates to a kind of machine winding, more particularly to a kind of novel double-layer wave that can save leading-out terminal wiring space around
Group method.
Background technique
The double-deck wave winding, which is connected in machine winding, to be widely used, especially rotor windings.There are two types of pass for the double-deck wave winding
The connection type of system: one end outlet and both ends outlet, as shown in Figs 1-4, with 4 pole, 24 slot, it is whole away from, all the way, rotor bilayer wave around
For group, the characteristics of analyzing two kinds of conventional coupling arrangements.According to the displaying of Fig. 1-Fig. 4, traditional rotor wave winding, both ends outlet
It is as follows with comparison the characteristics of the outlet of one end:
The double-deck wave winding of conventional double wave winding connection type one end outlet, advantage is: 1., can incude maximum electrical potential；
2., be suitable for all pole count machines.The disadvantage is that: 1., leading-out terminal wiring space it is nervous, can be seen that from Fig. 1 and Fig. 2, leading-out terminal is equal
It is furnished with (rotor slot number+6) a terminal, it is nervous that end-to-end welds space.
The double-deck wave winding of conventional double wave winding connection type both ends outlet, advantage is: 1., with to interpolar connection saving
A piece jumper, material saving alleviate leading-out terminal wiring space anxiety problem, can be seen that from Fig. 3 and Fig. 4, leading-out terminal is uniformly distributed
Have and is equal to the several terminals of rotor slot.The disadvantage is that: 1., a conductor, induced potential accordingly reduce every phase less in magnetic field；②,
It is circumferentially not symmetrical because will appear the noise of twice of slip frequency and change layer line, it the reason of influencing mechanical balance, should not use
On 6 multiple pole motor；3., outlet cannot use delta connection.
Summary of the invention
The purpose of the present invention is in view of the deficiency of the prior art, by changing the double-deck wave winding connection type,
A kind of novel double-layer wave winding method that can save leading-out terminal wiring space is provided；1., maximum electrical potential can be incuded, 2., be suitable for
3. all pole count machines, can alleviate leading-out terminal end wiring space anxiety problem, 4., outlet can be linked to be Y connection and △ connects
Method.
Technical solution of the present invention: one kind can save the novel double-layer wave winding method of leading-out terminal wiring space；With rotor 4
24 slot of pole, it is whole away from, all the way for connection, it is characterised in that connection method are as follows: the connection pole U phase N lower coil first, the even length of 1-8
Away from, then connect 3 it is whole away from, then connect the short distance of 2-7, finally connect 3 it is whole away from；Complete the connection that U phase N extremely belongs to down same phase coil, U
The connection method of the pole phase S lower coil is identical, even the length of 7-14 away from, then connect 3 it is whole away from then connecting the short distance of 8-13, finally connect 3
It is whole away from；Current direction in slot is finally pressed, by this two big group coil series connection, i.e., connects under the pole N tail 19 and under the pole S tail 1, constitutes a phase
Winding.
When U phase N pole lower coil of the present invention connects, even the length of 1-8 away from, then connect 3 it is whole away from then connecting the short distance of 2-7, finally connect
3 it is whole away from specifically: from head-1 U1-(on 1+it is long away from 7=8 under)-(under 8+whole away from 6=14 on)-(on 14+it is whole away from 6=20
Under)-(under 20+whole away from 6=24+2, i.e., on 2)-(on 2+short distance 5=7 under)-(under 7+whole away from 6=13)-(on 13+it is whole away from 6=
Under 19) under-19-pole U phase N tail.
When U phase S pole lower coil of the present invention connects, even the length of 7-14 away from, then connect 3 it is whole away from then connecting the short distance of 8-13, finally
Even 3 it is whole away from specifically: from head-7 U2-(on 7+it is long away from 7=14 under)-(under 14+whole away from 6=20 on)-(on 20+it is whole away from 6
=24+2, i.e., under 2)-(under 2+whole away from 6=8)-(on 8+short distance 5=13 under)-(under 13+whole away from 6=19)-(on 19+whole
Away from 6=24+1, i.e., under 1) under-1-pole U phase S tail.
It when wave winding of the present invention connects, detours one week per awave, expands a long slot first, after having connected a circle, step back one
Slot is attached again；The non-full-pitched coil of the two adjacent is all at a distance from pole center line all equally to reduce one
A slot, where conductor at flux density it is equal, the potential of induction is equal, and actual stride is all short distance, and fundamental wave chording factor is equal
And less than 1.
There are three types of span: 1., in back pitch, under connecting 7 on 2, under connecting 13 on 8, span 1-6；2., in back pitch, 8 are connected on 1
Under, under connecting 14 on 7, span 1-8；3., remaining is complete whole away from span 1-7.
The solution have the advantages that: by changing the double-deck wave winding connection type, turn so that leading-out terminal is evenly equipped with to be equal to
The several terminals of pilot trench alleviate leading-out terminal end wiring space anxiety problem, and the spacing between adjacent terminal is maximum, and head welds
The operating space connect is maximum, facilitates to the full extent and head welding operates；All at one end, outlet can connect for the wiring end to end of every phase
At Y connection and delta connection.
