Abstract
A single-layer winding high-voltage three-phase motor with q being 6/7/8 belongs to the technical filed of three-phase motor manufacture. The background technology is that, for the high-voltage three-phase motor with q being6/7/8, the winding spans Y are respectively expressed by Y=2q, the comprehensive harmonic intensity thereof is consistent with that of the full pitch, but the fundamental wave winding coefficient Kdp1 is 86.6% of that of the full pitch; if a single-layer winding is adopted, the Kdp1 is full pitch winding coefficient, but the harmonic intensity is not increased; the table 2 is a single-layer chain and cross-type winding-inserting table; the single-layer winding to the original double-layer stack winding iron core length coefficient is calculated to be: X=0.886*0.95=0.8227; and analysis and comparison are carried out, so that iron core is reduced (flux density is increased and iron loss is still reduced), no layer interval is achieved (stator slot depth can be reduced, and flux density is reduced), copper wires are nearly not increased, rotor aluminium loss is reduced, and a low-carbon effect is achieved.
Description
Technical field threephase motor manufactures
Background technology MgO-ZrO_2 brick q is 6,7,8 high pressure threephase motors, and winding span Y is taken as Y=2q, and its comprehensive humorous intensity of wave is consistent with whole distance, but fundamental wave winding coefficient Kdp1 is whole distance: 86.6%.
Wang Huailin. talk and be applicable to the symmetrical winding coefficient formula not waiting circle. middle and small motor, 1996,23 (2): 28 ~ 29.The condition of providing is analysed for carrying out harmonic wave segmentation.
It is 6,7,8 high pressure threephase motors that summary of the invention background technology 2 calculates MgO-ZrO_2 brick q, winding span Y=2q, its comprehensive humorous intensity of wave is consistent with whole distance, but fundamental wave winding coefficient Kdp1 is 86.6% of whole distance, in table 1 (comprehensive humorous intensity of wave Em table).Use single layer winding instead, Kdp1 is whole apart from winding coefficient, but humorous intensity of wave does not increase.Table 2 is individual layer chain and staggered form rule table.Calculate single layer winding to former double-layer overlapped around the long coefficient of iron core: X=0.886*0.95=0.8227.Com-parison and analysis iron core shortens (deduction magnetic close increasing still reduce iron loss), closely not to increase without interlayer (can reduce the stator slot degree of depth, fall magnetic close), copper cash, rotor aluminum depletion is few.There is low-carbon (LC) benefit.
Embodiment improves around comparing short distance degree with former double-layer overlapped, if manufacturability allows to implement.Increasing MgO-ZrO_2 brick q is to reduce harmonic wave, and analytical table 1, q increases to 7 humorous intensities of wave by 6 and reduces to: 4.317/4.444=0.971.But q increases to 8 humorous intensities of wave by 7 and reduces to: 4.284/4.317=0.9924, does not have meaning.The design of electrical motor tackling former q=8 changes q=7 into.
