Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the Y sections heart of the present utility model is made of three C cores 1 that are mutually 120 °.Each C core 1 is made of several lamination groups, and each lamination group is formed by several layers lamination stack.Each C core 1 comprises the stem part 11 that is used to overlap coil and does not overlap coil, only plays the iron yoke part 12 of closed magnetic circuit effect.Each layer lamination is banded hexagon, the lamination two ends are wedge angle, the angle of described wedge angle is 120 °, is positioned at the top of each the C core iron yoke lamination partly on one deck to dock mutually, and the seam of the lamination of the C core iron yoke part of adjacent two layers staggers mutually.
Fig. 2 shows the schematic diagram of the lamination of the utility model first execution mode.The two ends of lamination 2 are wedge angle, and the angle of wedge angle is 120 °.And, two limits of wedge angle and be 60 ° by the angle between the normal on wedge angle summit.One spacing k is arranged between the summit of wedge angle and the longitudinal centre line of lamination.In the present embodiment, the summit of the wedge angle of the summit of the wedge angle of lamination 2 upper ends and lamination 2 lower ends is distributed in the both sides of lamination longitudinal centre line X, and the spacing of the summit of the wedge angle of lamination 2 upper ends and lamination longitudinal centre line X equals the summit of wedge angle of lamination 2 lower ends and the spacing of lamination longitudinal centre line X.When each C core of the Y sections heart adopted the lamination of present embodiment, the lamination of each C core adjacent two layers adopted about the lamination longitudinal centre line 180 ° of modes that stack of overturning mutually.Its lamination figure as shown in Figure 3.Solid line partly shows the seaming position that is positioned at three laminations of three C core iron yoke parts on one deck, and dotted portion shows the seaming position of three laminations of three C core iron yoke parts on one deck below this layer.Adopt present embodiment, as long as adopt a kind of lamination sheet shape as shown in Figure 2, just can realize the overlap joint of the Y sections heart, technology and manufacturing are all very easy.
Fig. 4 A and 4B show the lamination of second execution mode of the present utility model respectively.In second execution mode, each lamination group of each C core comprises three layers of lamination, and described three layers of lamination comprise two-layer corner lamination 3 and one deck standard lamination 4.Corner lamination 3 is shown in Fig. 4 A, and its two ends are wedge angle, and the angle of wedge angle is 120 °.The summit of two ends wedge angle is positioned on the longitudinal centre line X of lamination.Limit of each wedge angle and the angle of longitudinal centre line X are 55 °, and the angle of another limit and longitudinal centre line is 65 °.In Fig. 4 A, 55 ° of angles of upper end wedge angle are positioned at the left side of longitudinal centre line X, and 55 ° of angles of lower end wedge angle are positioned at the right side of longitudinal centre line.In another embodiment, also 55 ° of angles of 55 ° of angles of upper end wedge angle and lower end wedge angle can be arranged in the same side of longitudinal centre line.Fig. 4 B shows standard lamination 4, and its shape is about the longitudinal centre line X symmetry of lamination 4.The summit of lamination 4 two ends wedge angles is positioned on the longitudinal centre line X of lamination, and two limits of each wedge angle and the angle of longitudinal centre line X are 60 °.Each C core of the Y sections heart adopts the lamination 3 and the lamination 4 of present embodiment can realize multistage overlapping the slot, and its lamination figure as shown in Figure 5.In each lamination group, two-layer corner lamination 3 overturns mutually 180 ° about the lamination longitudinal centre line and stacks.Preferably, one deck standard lamination 4 can be positioned over the centre of two-layer corner lamination.The solid line of Fig. 5 partly shows the seaming position of three corner laminations of three the C core iron yokes part that is positioned at the upper strata, and dotted portion shows the three corner laminations on this layer lower two layers and the seaming position of three standard laminations.
Only adopt the corner lamination 3 shown in Fig. 4 A also can realize two-stage seam, at this moment, only need corner lamination with each C core adjacent two layers overturn mutually 180 ° and stack about the lamination longitudinal centre line as first execution mode.And in each lamination group of each C core, adopt two-layer lamination shown in Figure 2 and the standard lamination of one deck shown in Fig. 4 B, by the stack mode identical, also can realize multistage overlapping the slot with second execution mode.The sheet shape of lamination of the present utility model is not limited to the lamination shown in Fig. 2 and Fig. 4 A, as long as in the lamination of the C core of adjacent two layers, the shape of one deck lamination can realize overlap joint about the longitudinal centre line of lamination is asymmetric at least.
Owing to adopt overlap joint to engage between the iron yoke of three C cores of the Y sections heart of overlapping the slot of the present utility model, thereby have the advantage that the seam crossing magnetic resistance is little, no-load loss is low and no-load current is little.Compare with widely used three-phase three-column plane laminated core, magnetic circuit is short, and magnetic resistance is little, the three-phase magnetic circuit symmetry.Therefore, not only saves material but also reduced no-load loss, reduced the harmonic wave that produces owing to three-phase is asymmetric, and the seam number only is three-phase three-column plane laminated core half to have littler no-load current.
Though description of the present utility model combines certain embodiments, but it should be understood by one skilled in the art that the utility model is not limited to embodiment described here, and can carry out various modifications and variations and do not deviate from spirit and scope of the present utility model.
