Group.
Background technology
Without speed governing occasion, the popularization of energy-saving electric machine and it is of practical significance very much, asynchronous starting synchronous permanent-magnet motor
Machine arises at the historic moment with regard to this, but the cage-shaped structure of asynchronous starting permasyn morot is different from common asynchronous machine, while rotor
On permanent magnet also be present, therefore it is also poorer than common asynchronous machine to start ability, and normal asynchronous removes low-power machine one
As star connection directly initiate outer, remaining is mostly star --- triangle starts, and permasyn morot is often then star
Shape connection, therefore starting current multiple is bigger during startup, especially two pole asynchronous starting permasyn morots, which start, is more difficult to, and is
Improve two pole asynchronous starting permasyn morots to start and pull-in performance, had in the past in terms of permanent magnet rotor structure many excellent
Change scheme, do not go to be related to herein, and stator winding end length is presently, there are in terms of stator winding, stator the harmonics of magnetic force is more, instead
Electromotive force harmonic content is high, in order to avoid counter electromotive force produces circulation in delta connection, star connection can only be used to work, no
Star can be used --- the outstanding problem such as deltic method startup, two pole asynchronous starting permasyn morots are limited as section
The popularization of energy motor, on the other hand, two pole asynchronous starting permasyn morot stator winding of optimization, turn into an important improvement side
Face.
The content of the invention
It is an object of the invention to be optimized for two pole asynchronous starting permasyn morot stator winding, mesh is overcome
Preceding this kind of motor stator winding can not use star only with star connection --- and deltic method starts；And stator
Winding terminal minister, stator winding the harmonics of magnetic force content is big, and counter electromotive force harmonic content is big, influences startability and permanent magnet perseverance magnetic
The problems such as ability, a kind of two new pole asynchronous starting permasyn morot stator winding are invented, this winding overhang is short, fixed
Sub- the harmonics of magnetic force content is less than 2.0%, harmonic wave of the back-emf harmonic wave without 3 times and 3 odd-multiple number, during delta connection, three
Angular interior no counter electromotive force circulation, can use star --- and triangle starts method, limiting starting current multiple, improves and starts
Performance and pull-in performance, permanent magnet eddy-current heating is reduced, effectively prevent permanent magnet failure demagnetization.
The present invention is achieved like this, and a kind of two pole asynchronous starting permasyn morot stator winding, its feature exists

Embodiment
For the sake of becoming apparent from, it is described in more detail in conjunction with specific embodiments.
A kind of two pole asynchronous starting permasyn morot stator winding, motor stator slot number are 36 grooves, number of poles 2
Pole, the number of phases are 3 phases, and rotating speed is 3000 revs/min, power of motor 55Kw, and stator line gauge is 2- Φ 1.3,8-1.4 and around three layers
Stacked, per line of rabbet joint number 10, connection be 1 Δ, the cylindrical Φ 400mm of stator core, stator core inner circle Φ 225mm, and stator core is grown
Spend 180mm, stator winding coil arrangement as shown in figure 1,
Fig. 1 A phase winding coarse pitch coils, Y1=1-16, totally 6 figure, it be 5 circles often to enclose the number of turn, is arranged as follows：1-16,2-17,
3-18；36-21,35-20,34-19, from the 1st groove and the 19th groove lead-out wire, line end is respectively labeled as a1, x1,
Pitch coil in Fig. 2 A phase windings, Y2=1-10 6 are enclosed totally, and it is 4 circles often to enclose the number of turn, and arrangement is as follows：4-13,5-14,
6-15,33-24,32-23,31-22；From the 4th groove and the 22nd groove lead-out wire, line end is respectively labeled as a2, x2,
Fig. 3 A phase winding fine pith coils, Y3=1-4 6 are enclosed totally, and it is 1 circle often to enclose the number of turn, and arrangement is as follows：7-10,8-11,
9-12,30-27,29-26,28-25；From the 7th groove and the 25th groove lead-out wire, line end is respectively labeled as a3, x3, under fine pith coil
Three stackings are formed in groove around coil in notch under the middle part of groove, coarse pitch coil under the bottom of groove, middle pitch coil
The turn ratio is followed successively by 5 from coarse pitch to fine pith：4：1, Fig. 1, Fig. 2, Fig. 3 only depict the arrangement of A phase winding coils, B phases, C phases
Winding coil layout drawing is omitted and is not drawn into, three-phase A, B, C winding 120 ° of electrical angles of mutual deviation, formation three-phase symmetrical structure, therefore motor
Be three layers in 36 grooves, all be 5+4+1=10 per line of rabbet joint number, the connections of three-phase windings as shown in figure 4, parallel branch number is 1, because
The winding a being made up of for A phase windings three kinds of coils1x1, a2x2, a3x3, so what corresponding B phase windings were also made up of three kinds of coils
Winding b1y1, b2y2, b3y3, winding c that C phase windings are also made up of three kinds of coils1z1, c2z2, c3z3, wherein b1y1, b2y2, b3y3,
c1z1, c2z2, c3z3Coil layout drawing omits, not shown to draw, when therefore A, B, C three-phase symmetric winding are often in parallel, circuitry number is 1,
Delta connection as shown in Figure 4 is a1-x1-a2-x2-a3-x3-b1-y1-b2-y2-b3-y3-c1-z1-c2-z2-c3-z3-a1Form three
Angular connection, from a1z3Tie point draws leading-out terminal mark A, from b1x3Tie point draws leading-out terminal mark B, from c1y3Tie point draws
Go out leading-out terminal mark C, during startup, then such as common mouse cage asynchronous machine star --- delta connection starts.Common pitch Y=1-
14 double-layer laps are around winding coefficient computation formula, the subharmonic content of counter electromotive force 3 can be obtained accordingly
There is very big circulation up to 6.41%, during delta connection, therefore delta connection can not be used, the multiple the harmonics of magnetic force content of stator is big
In 3.5%, and three-phase windings of the present invention, by it, deployment scenarios, the universal calculation equation of its winding coefficient can be written as in groove
It can analyze and calculate its 3 times and 3 odd number multiple harmonic winding factor is zero accordingly, its harmonic wave total content is less than
2%, harmonic content reduces 43.5%, thus this three stacking around having the technical effect that of reaching of stator winding：
1. stator winding end is three-dimensional three end faces, contracted than pitch for Y=1-14 normal conventional double-layer lap winding overhangs length
It is short by 20%；
2. stator winding the harmonics of magnetic force content than pitch be Y=1-14 double-layer laps around, reduce 43.5%, beneficial temperature rise reduce,
Permanent magnet vortex is reduced, and permanent magnetic energy power improves；
3. counter electromotive force 3 times and 3 odd-multiple times harmonic winding coefficient are zero, three-phase windings delta connection, star
Shape --- delta connection starts, and starting current is small, starts ability and permanent magnet demagnetizing effect is reduced, also make permanent magnet perseverance magnetic energy
Power improves；
4. stator magnetic potential sine improves, make that rotor cage harmonic impedance is small, and electric current is big, pull in performance improvement.
It can be seen that three stackings of the invention are short around stator winding end, harmonic content is small, delta connection aspergillus ficuum, can be with
Using star --- delta connection, start, performance of pulling in is greatly improved, and it is same to overcome current two pole asynchronous starting permanent magnetism
Step motor uses pitch to be changed for Y=1-14 common doubles, and stator winding end existing for winding is long, and stator the harmonics of magnetic force is more, instead
Electromotive force harmonic content is high, in order to avoid counter electromotive force produces circulation in delta connection, star connection can only be used to work, no
Star can be used --- deltic method starts work and poor performance of pulling in, same so as to limit two pole asynchronous starting permanent magnetism
The prominent technical problem such as popularization and application of motor is walked, has reached the purpose of invention.
