Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1.Be provided with rectangle magnet steel jack 1 in the outer annular of rotor punching symmetrically, rectangle magnet steel jack 1 is acute angle and obtuse angle with the rectangle magnet steel jack of both sides respectively, and be in the shape of the letter V distribution, and rectangle magnet steel jack 1 has 16.Duplicate removal hole 2 and riveted holes 3 is arranged with in the middle part annulus of rotor punching.The center of rotor punching is provided with punching axis hole, punching axis hole is provided with riveted holes 3 in 1
o~ 5
othe key bossing 4 of angle.Duplicate removal hole 2 has 8, and riveted holes 3 has 4, symmetrical, and duplicate removal hole 2 is mounting hole, and duplicate removal hole 2 is every magnetic space.Key bossing 4 is keyway space, ensures that the permanent magnet of rotor alternately deflects certain angle every a segment distance in the axial direction.
As shown in Figure 2.Rotor part 6 laminates certain thickness by rotor punching and forms, and laminates rear employing rivet 5 and rivets tightly.Be inserted with permanent-magnet steel in the rectangle magnet steel jack 1 of rotor part 6, rivet 5 is positioned at riveted holes 3.
As shown in Figure 3, Figure 4.Rotor 7 is spliced in opposite directions by rotor part 6, two rotor part 6 arranged opposite adjacent during splicing, ensures that the rivet head of rivet 5 on adjacent rotor parts 6 is positioned at the duplicate removal hole 2 of adjacent rotor parts 6.Key bossing 4, when rotor part 6 loads machine shaft, makes rotor surface form staggered N magnetic pole 8, S magnetic pole 9, and the angle that staggered degree is deflected by key bossing 4 determines.
