Example.
The stator structure of big induction permanent magnet synchronous motor as shown in Figs. 1-2, including stator core 10, the first conducting wire 70,
Second conducting wire 80 and privates 90；Stator core 10 offers the first wire casing unit, the second wire casing unit and third wire casing list
Member, the first wire casing unit, the second wire casing unit and third wire casing unit are arranged successively around 10 central axial direction of stator core；
The first wire casing unit includes wire casing 11 and the first outer wire casing 12 in first, wherein wire casing 11 and the first outer 12 court of wire casing in first
Direction far from 10 central axis of stator core is arranged successively；The second wire casing unit includes wire casing 13 and the second outside line in second
Slot 14, wherein wire casing 13 and the second outer wire casing 14 are arranged successively towards the direction far from 10 central axis of stator core in second；It should
Third wire casing unit includes the outer wire casing 16 of wire casing 15 and third in third, wherein in third wire casing 15 and the outer wire casing 16 of third towards remote
Direction from 10 central axis of stator core is arranged successively；First conducting wire 70 passes through wire casing 11 and the first outer wire casing 12 in first and twines
It is wound on stator core 10, to form the first phase coil winding 20；Second conducting wire 80 passes through wire casing 13 and the second outside line in second
Slot 14 is wrapped on stator core 10, to form the second phase coil winding 30；Privates 90 passes through wire casing 15 and the in third
Three outer wire casings 16 are wrapped on stator core 10, to form third phase coil windings 40.
On the basis of above structure, external power supply is used to power for the stator structure of this big induction permanent magnet synchronous motor,
At this point, the stator structure of this big induction permanent magnet synchronous motor is analyzed and solved in two dimensional field, permanent-magnet synchronous is not considered
The end effect of motor；
(1) 10 magnetic conductivity of stator core is infinity.
The winding self-induction of ordinary motor is generally solved by derivation formula
In formula: m --- number of motor phases；N --- every phase winding the number of turns；Kdp1 --- winding coefficient；P-- motor number of pole-pairs；
Lef --- core length；δ ef --- gas length；μ 0 --- air permeability.
But in the stator structure of this big induction permanent magnet synchronous motor, since stator core 10 has opened up interior wire casing and outside line
Slot, and coil windings pass through interior wire casing by conducting wire and outer wire casing is wound, therefore its magnetic circuit is different from ordinary motor, it is therefore desirable to
Its inductance is analyzed.
In terms of actual angle, by taking the first phase coil winding 20 as an example, when being powered to the first phase coil winding 20, the first phase
Part and first conducting wire 70 of first conducting wire 70 of coil windings 20 in wire casing 11 in first pass through the first outer wire casing 12
Part successively constitutes a complete first phase coil winding 20.
In this way, remember that current effective value is Ie in the first phase coil winding 20 when being individually powered to the first phase coil winding 20,
Magnetic linkage across entire first phase coil winding 20 is ψ coil, at this point, then the electric induction of the first phase coil winding 20 should be by the phase
First conducting wire 70 passes through in first that inductance caused by the part of wire casing 13 connects to obtain in wire casing 11 and second, i.e., to formula
[1] it is converted, be can be obtained:
Furthermore in order not to be convenient for the explanation calculated and physically, therefore [2] are converted, first:
ψcoil=ψs+ψδ [3]
ψ s is the magnetic linkage value for the part that the first conducting wire 70 passes through in first in wire casing 11, ψ in formulaδIt is passed through for the first conducting wire 70
The magnetic linkage value of part in first outer wire casing 12.
Secondly as assuming η in stator core 10Fe=∞, it is believed that the first conducting wire 70 passes through in first in wire casing 11
Part and the first conducting wire 70 pass through the first outer wire casing 12 in part caused by magnetic linkage be independent of each other.Wherein, the first conducting wire
70 partially pass through 10 inner space of stator core in wire casing 11 in first, and generated magnetic linkage ψ s is in big induction permanent magnet
In synchronous motor, 50 magnetic field interaction of permanent magnet with the big induction permanent magnet synchronous motor realizes energy converting between mechanical；First
Conducting wire 70 pass through the first outer wire casing 12 in part not with 50 magnetic field interaction of permanent magnet of the big induction permanent magnet synchronous motor,
Generate leakage inductance.Therefore, in conjunction with formula [3], formula [2] can be written as:
In formula: LsFor the inductance of 20 inside of the first phase coil winding, the self-induction being equivalent in existing motor；LδIt is led for first
Line 70 passes through leakage inductance, the leakage inductance and L caused by the first outer 12 part of wire casingsSelf-induction series connection.
As a result, as shown from the above formula, relatively existing motor, this big induction permanent magnet synchronous motor increase stator core 10
Outside leakage inductance, and by common knowledge it is found that additional leakage inductance numerical value is easy to reach ten times of self-induction or more, therefore relatively existing electricity
The stator structure of machine, this big induction permanent magnet synchronous motor greatly improves the inductance of big induction permanent magnet synchronous motor entirety, into
And inhibit the generation of current harmonics, it is ensured that the control accuracy of big induction permanent magnet synchronous motor.
Further, the cell wall of wire casing 11 is in closing structure on radial section in first；The cell wall of first outer wire casing 12
It is in closing structure on radial section；On the basis of the structure, obtained through analysis and solution:
The inductance of any one circuit can be write as:
In formula: the π of ω=2 f-alternating current angular frequency；X-winding reactance.
Therefore, under certain frequency, calculate inductance the problem of can be attributed to how the winding reactance X of counting circuit.Around
Group reactance can substantially be divided into two major classes: 1) principal reactance；2) leakage reactance (or abbreviation leakage reactance).
Calculate principal reactance when assume: 1) in armature groove portion conducting wire current convergence in groove center；2) 10 magnetic conductivity η of stator core
=∞；3) influence of the notch of wire casing is with Carter's coefficient Kδ(Carter's coefficient) counting and.
In synchronous motor, traditionally principal reactance is referred to as the reactance of armature reaction, i.e. this big induction permanent magnet synchronous motor is determined
The reactance of armature reaction of minor structure is equal to principal reactance, i.e.,
In formula
And the long δ of effective air gapef=Kδδ
From the foregoing, it will be observed that winding reactance is directly proportional to than magnetic conductance, it is inversely proportional than magnetic conductance and Carter's coefficient.
Wherein, Carter's coefficientAccording to common knowledge it is found that and for being in closing structure on section
Wire casing 11 or the first outer wire casing 12, ignore magnetically saturated influence, Carter's coefficient 1 in first；And for the line with notch
Slot, Carter's coefficient are greater than 1；Therefore there is the wire casing of notch relatively, wire casing 11 and the first outer wire casing in first in the present embodiment
12 structures being closed using cell wall, can be improved than magnetic conductance, and then improve the inductance of big induction permanent magnet synchronous motor.
