Abstract

This invention relates to the manufacture of electromotors, which brings double-layer lap wound symmetric un-equal turns into a single-winding multipole double-speed motor to weaken harmonics, in which, the invention solves the harmonic sum computation of 120 degree phase belt and applies An Excel weight number visual technology to seek the span and turn ratio enabling the 5, 7 times of winding coefficients of the base and multipole lower thatn the 5, 7 times winding coefficients of single speed equal turn general span to q=4, 6, 8 and 10( the base is each pole/phase, the multipole is each pair of poles/phase slot number), which can be used in reducing noises and increasing the minimum torque.

Description

The single winding multiple pole double speed motor non-uniform turn winding
The technical field motor is made
Background technology Wang Huai woods. to talk and be applicable to that symmetry does not wait the winding coefficient formula of circle. middle and small motor, have 60 degree facies tract formula at 1996,23 (2): 28～29, and parameter q+0.5-0.5Y is arranged, and provides condition for releasing 120 degree facies tract formula.
Summary of the invention simplex winding multiple-speed motor is because winding harmonic wave composition height, noise is higher than single-speed motor (for example 83 decibels of Y90S-2 noise criterias of YD90S-4/2 noise criteria are 1 grade/2 grades 70/75 decibel), pull up torque is not high, can not satisfy specific (special) requirements and can't adjust (losing order sometimes) when (comprising export requirement) separately yet.In single-speed motor, people extensively use double-deck lap wound symmetry not wait the circle winding to remove to weaken the winding harmonic wave.The present invention tries to achieve double-deck lap wound symmetry with Excel flexible strategy visual techniques not wait the circle scheme.In the scheme 5 times, 7 winding coefficients are lower than the winding coefficient of the general spans of circle such as single speed.Can be used for making existing product to reduce and make an uproar, improve pull up torque, improve times utmost point power factor.The method of scheme can be used for the product design and the directive improvement of product of power Turn Ratio Changing.Single winding multiple pole double speed motor of the present invention is base stage 60 degree facies tracts, the winding of times utmost point 120 degree facies tracts.Calculate the winding coefficient that does not wait circle and need 60 degree and 120 degree facies tract summation winding coefficient formula.Formula q value is every extremely every phase groove numbers for 60 degree facies tracts, is every pair of extremely every phase groove numbers for 120 degree facies tracts.Y is a span groove number.Formula calculates with Excel and only needs the slot pitch number of homophase group first groove to homophase group symmetry axis.Trying to achieve 60 degree facies tracts is: q+0.5-0.5Y; 120 facies tracts are: 0.25q+0.5-0.5Y.
Excel flexible strategy visual techniques layout: A2 is every extremely every phase groove number, and B2 is a span, C2=A2+0.5-0.5*B2, and C3=C2+1 chooses C3 to be filled to C11 automatically, groove flexible strategy that Here it is.D2～D11 imports the corresponding number of turn (contain zero circle, wait circle also can get 1 entirely).D12=SUM (D2:D11) E1 input 1, F1 input 5, G1 input 7.E2=$D2*COS (F$1*3.1415926*$C2/3/$A$2) chooses E2 to be filled to E11 automatically.Groove flexible strategy effect that Here it is.E12=SUM (E2:E11) Here it is groove flexible strategy effect and.E13＝E12/$D$12。C15＝0.25*A2+0.5-0.5*B2。C16=C15+1 chooses C16 to be filled to C24 automatically.D15=D2 chooses D15 to be filled to D25 automatically.E15=$D15*COS (E$1*3.1415926*$C15/1.5/$A$2) chooses E15 to be filled to E24 automatically.E25＝SUM(E15：E24)，E26＝E25/$D$25。Choose E2 to E26 to be filled to G26 automatically.
Utilizing Exce1 flexible strategy visual techniques layout, is that 4,6,8,10 single winding multiple pole double speed motors are tried to achieve the relevant turn ratio of table 1, table 2 winding scheme to the every extremely every phase groove number of base stage.According to the specification of using non-whole distance (for 120 degree facies tracts) winding is arranged in the product,, try to achieve by the relevant turn ratio and can implement number of turn scheme doubly extremely putting in order the specification of distance in the product.Do not wait the calculating formula that does not wait circle arbitrarily of circle winding in the table arbitrarily, do not describe in detail.
Among description of drawings Fig. 1 to homophase group first groove titled with 3q+1 get 60 degree facies tracts first grooves to homophase group symmetry axis apart from the groove number: [3q+1-(Y+q)]/2=q+0.5-0.5Y.To homophase group first groove titled with 3q/2+1 get 120 degree facies tracts first grooves to homophase group symmetry axis apart from the groove number: [3q/2+1-(Y+q)]/2=0.25q+0.5-0.5Y (with the right angle trigonometry type method of background technology also this result).Fig. 2 is that the double-deck symmetry of q=6 Y=8 does not wait the circle schematic diagram.1 pair of upper strata triangle 9 of lower floor's square frame in the drawings, the dislocation groove is several 2, equals=Y-q.(here because Y always about 1.5q).Figure the right groove inner wire number is a+b; A+c; B+c.
The embodiment table of comparisons 2 is carried out the line mould and has been calculated wire gauge and can manufacture experimently that (base stage reduces to mend with assorted consumption and tastes copper loss and increase, times utmost point reduces with assorted consumption and electric current reduce to mend taste the copper loss increase). when performance does not meet the demands, can be equipped with corresponding groove area (groove depth the is constant) stator punching that do not wait by table 1, reduce stator resistance, make performance all-round excellent. from Excel flexible strategy visual techniques computational process as can be seen, the method of scheme can be used for the product design and the directive improvement of product of power Turn Ratio Changing. and the first-harmonic that promptly biases toward a certain number of poles increases or harmonic wave weakening. for YD90L-4/2, I once changed 64/64/64/64 circle into 51/77/77/51 circle, span Y=6 is constant, levels dislocation groove number=6-4=2, groove inner wire number is: 128/128/128/128. for 4 utmost points, primary winding coefficient 1/5/7 is 0.863/0.126/0.126. trial result, starting torque/breakdown torque/pull up torque: former 2.59/2.79/1.10 for 0.837/0.224/0.224. changes the back; Existing 2.28/3.06/2.19. noise: former 74.1; Existing 61.5. temperature rise: former 63.6; Existing 53.4. power factor: former 0.772; Existing 0.794 efficient: former 76.53 (22.8 watts of the assorted consumptions of actual measurement); Existing 79.32 (getting 0.5%, 8.2 watt). if 5 subharmonic are approaching zero, starting torque can be stablized.
