Preferably, the coil being wound on the the the the the the the the the the the the the the the 35th, 36,1,2,5,6,7,8,11,12,13,14,17,18,19,20,23,24,25,26,29,30,31,32 grooves is homophase; Be wound on coil on the the the the the the the 3rd, 4,9,10,15,16,21,22,27,28,33,34 grooves for homophase not.The coil of homophase groove (sense of current is identical) is removed to layer insulation and merge into individual layer, the coil of homophase (sense of current is not identical) does not still keep double-deck, and their end is connected along the sense of current by concentric type, from in becoming single two layer winding, make effective span of winding by original 1-14, become 1-17.
The utlity model has following beneficial effect:
Field waveform improves, and has reduced stray loss, has improved starting performance and electric efficiency.
Brief description of the drawings
Fig. 1 is the winding construction schematic diagram of the high efficiency motor with single two layer winding of the utility model preferred embodiment.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, a kind of high efficiency motor with single two layer winding, it comprises stator slot, the groove number of described stator slot is 36 grooves, number of poles 2 utmost points, the number of phases 3 phases (A, B, C phase), every extremely every phase groove is counted q=6.
U1 draws from the 4th groove, and U2 draws from the 22nd groove; W1 draws from the 28th groove, and W2 draws from the 10th groove; V1 draws from the 16th groove, and V2 draws from the 34th groove.
Every group of coil number is 4, and pitch is respectively 1-18,2-17,3-16 and 4-15; Wherein, 35th, 36,1,2,5,6,7,8,11,12,13,14,17,18,19,20,23,24,25,26,29,30,31,32 grooves are individual layer groove, thereby formation single layer winding, 3rd, 4,9,10,15,16,21,22,27,28,33,34 grooves are double-layer groove, thereby form two layer winding.
The coil being wound on the the the the the the the the the the the the the the the 35th, 36,1,2,5,6,7,8,11,12,13,14,17,18,19,20,23,24,25,26,29,30,31,32 grooves is homophase; Be wound on coil on the the the the the the the 3rd, 4,9,10,15,16,21,22,27,28,33,34 grooves for homophase not.
The number of turn of every groove can be determined as required.
Single two layer winding and single layer winding comparison, have the advantages such as good field waveform, starting performance and lower stray loss.Compared with two layer winding, single two layer winding, in the time of shorter actual coil span, can obtain larger effective span, and fundamental factor is greatly improved, and in 2 utmost point motors, effect is especially remarkable.Along with the raising of winding coefficient, every groove conductor number can reduce, and copper cash area can be increased, and efficiency improves.That is to say, same stator and rotor cores length, is used single two layer winding compared with common winding, in the situation that obtaining same efficiency, can save material.As: YE2-280M-2 motor, changed into after single two layer winding by two layer winding, winding type adopts 2-4-2, fundamental wave winding coefficient brings up to 0.9416 by 0.866, has improved 8.73%, makes the actual number of turn can reduce 8.73%, wire glass strengthens 8.73%, stator resistance declines, and efficiency improves, and temperature rise reduces.
Former two layer winding inserting-coil process is equivalent to 2/3 short distance, and field waveform is poor, adopts after single two layer winding as shown in Figure 1, and field waveform improves, and has reduced assorted consumption, has improved starting performance and electric efficiency.
Table 1 YE3-280M-2(90kW 2 utmost points) double-deck and single two layer winding contrast test
| Project | Assorted consumption (W) | Efficiency (%) | Temperature rise (k) |
| Double-deck | 1437 | 93.6 | 72 |
| Single double-deck | 925 | 94.2 | 66 |
When Winding Design, every groove number of turn is selected more flexible, the fine setting of the number of turn of can accomplishing to be often in series.In common individual layer or two layer winding, can only accomplish that every groove conductor number increases and decreases a circle, and in single two layer winding, can accomplish to increase and decrease a circle at individual layer or double-deck indivedual grooves, quite every groove on average increases and decreases several circles at zero point.Therefore, the Electromagnetic Design scheme that single two layer winding can select the conductor number that is reasonably often in series to obtain, is particluarly suitable in the motor of relatively high power.
For a person skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and distortion, and these all changes and distortion all should belong to the protection range of the utility model claim within.
