Description
Technical field
Motor is made
Background technology
Jinyang Chen Wei is quiet. and a bilayer does not wait the preferred arrangement of circle winding. and middle and small motor, copper factor optimizations such as 1994,21 (4): 14～17 employing uiform sections are different from the present invention.
Wei Aimin singly loves and respects Li Li. the research of the practical Sine distribution winding of three-phase. and middle and small motor, 1996,23 (1): 7～11.In the table 1 q=5 in the turn ratio coefficient of winding cosine distribution, be the data of span 1-11.Be different from span 1-13 of the present invention.
Wang Huailin. talk and be applicable to that symmetry does not wait the winding coefficient formula of circle. middle and small motor, 1996,23 (2): 28～29.Formula is arranged, parameter q+0.5-0.5Y is arranged, condition is provided for the flexible strategy visual techniques.
Magnetic flux in the summary of the invention motor is produced by the winding magnetomotive force.The winding magnetomotive force of threephase asynchronous is by 1 time and 5 times, 7 times ... (6 multiple adds 1, subtracts 1) sinusoidal wave formation.Few more beyond 1 time, by near sinusoidal, motor performance is good more more for composite magnetic power.Formed coil is used for high-voltage motor.The formed coil winding electric machine of q=5, winding rule adopt a kind of among two kinds of 1-13 (span Y=12), the 1-14 (Y=13).The 1-13 quintuple harmonics is zero, and the seventh harmonic is 0.088; The 1-14 quintuple harmonics is 0.1, and the seventh harmonic is 0.016.Invention utilization Excel flexible strategy visual techniques is carried out double-deck lap winding symmetry to it and is not waited circle optimization.Try to achieve under the 1-13 span, the turn ratio of 0.72/1/1.2/1/0.72, corresponding quintuple harmonics is zero, the seventh harmonic is 0.00007.Enforcement can improve motor performance.Amplified the measure of small turn number sectional area of wire, can further be fallen winding resistance, improved electric efficiency.
Excel flexible strategy visual techniques layout: A2 is that every extremely every phase groove is counted q, and B2 is span Y, C2=A2+0.5-0.5*B2, and C3=C2+1 chooses C3 to be filled to C6 automatically, groove flexible strategy that Here it is.D2～D6 imports the corresponding number of turn (waiting circle also can get 1 entirely).D7＝SUM(D2：D6)。F1 input 1, G1 input 5, H1 input 7.F2=$D2*COS (F$1*3.1415926*$C2/3/$A$2) chooses F2 to be filled to F6 automatically.Groove flexible strategy effect that Here it is.F7=SUM (F2:F6) Here it is groove flexible strategy effect and.F8＝F7/$D$7。Choose F2 to be filled to H8 automatically to F8.F9＝COS((15-B2/A2)*3.1415926/3)，F10＝F8/F9。Literal in the layout and symbol: A1 is defeated to be: q, and B1 is defeated to be: Y, D1 is defeated to be: the number of turn or turn ratio, E1 is defeated to be: harmonic number, and E7 is defeated to be: right effectively series conductor number, E8 is defeated to be: winding coefficient (amplitude), E9 is defeated to be: short moment coefficient, E10 is defeated to be: breadth coefficient.
With to the explanation of 4 tables down, set forth and optimize.
Table 1,2,4th, the calculating that effective series conductor of 22 circles under 23 circles and the 1-14 span/23 circle schemes is counted result of calculation 104.6/102.9/107.6 and 5,7 subharmonic under the 1-13 span.Table 3 is the calculating that symmetry does not wait circle under the 1-13 span, and effectively the series conductor number is 106.3.Suppose that table 4 motor performance power factor has surplus, table 3 scheme is a table 1,2,4 replaceable scheme.Observing the contrast of 5,7 subharmonic is again desirable scheme only.
By accompanying drawing table 3 groove inner wire number is 43/43/48/50/48.
Table 3 his-and-hers watches 1 maintain an equal level by 50 circles and former 46 sectional areas, and the relative resistance ratio of table 3 his-and-hers watches 1 is calculated as follows: section ratio is: 46/50, the length ratio is: 116/115, and resistance and length are directly proportional and the cross section is inversely proportional to,
Resistance ratio is: 116/115*50/46=1.0964.
Table 3 his-and-hers watches 1, by amplifying the small turn number sectional area of wire, c+a=a+c=18+30=48,48 circles and former 46 circle sectional areas maintain an equal level (comprised 30 circles and got 46/50 sectional area), the cross section X of 18 circles is: 18*X+30*46/50=46, X=(46-30*46/50)/18, the resistance ratio of table 3 his-and-hers watches 1 is: [2*18*18/ (46-30*46/50)+(30+25*2) * 50/46]/115=1.0624.Because being this scheme of absolute coil, each coil of formed coil winding easily goes.

Description of drawings
Accompanying drawing has been expressed every extremely every phase groove and has been counted q=5, and the double-deck lap wound symmetry of coil spread Y=12 does not wait circle groove inner wire number: with 5 grooves is circulation section, and groove inner wire number is a+b/b+a/c+a/b+b/a+c.Can find out conveniently which groove inner wire counts maximum.
Embodiment
The former scheme of input writes down effective series conductor number in the EXCEL layout.Look into former performance, determine new effective series conductor number, and determine scheme, or continue to seek prioritization scheme with the harmonic wave that provides the result of calculation of the concrete number of turn in the EXCEL layout according to the improvement direction target.Determine to adopt one of lead 2 schemes at last.
Scheme implementation can improve the electric motor starting performance, reduces vibration, noise, reduces assorted consumption, reduces temperature rise.Assorted consumption of big motor and copper loss maintain an equal level, and the big motor of all q=5 is implemented, and helps reducing greenhouse effect.
Table 3 his-and-hers watches 1 effective series conductor ratio is 1.0163 (make motor reduce iron loss, slightly increase rotor aluminium consumption).Economizing copper 0.07 (116/115*46/50=0.93) improves surveying assorted power consumption engine efficiency.
