Tail fairing 5, motor wire-connecting board 6 and stator shield 7.The drive end bearing bracket 2 is mounted on the left side of motor housing by bolt 1,
The motor hood 5 is fixed on the right side of motor housing by bolt 1, and the rotor 4 is arranged inside electric machine casing, and rotor
4 are connect at the center of motor hood 5 by bolt 1, have been additionally provided with wound stator 3 between the rotor 4 and motor housing,
Described have wound stator 3 using straight groove structure, it is described have motor wire-connecting board 6 is further fixed on the right side of wound stator 3.
The rotor includes rotor core 8, shaft block ring 11, baffle 9, rotor punching assembly and wind deflector 14, described
By connecting at bolt and 5 center of motor hood, the rotor punching assembly fixation is nested in the rotor core rotor core 8
On 8, the rotor core 8, which is located on the two sides of rotor punching assembly, is provided with the shaft block ring 11；The rotor punching is total
At including straight rotor punching 15, the first oblique rotor punching 13 and the second oblique rotor punching 16, the straight rotor punching 15 is located at the
Between one oblique rotor punching 13 and the second oblique rotor punching 16, and the first oblique rotor punching 13 and the second oblique rotor punching 16 are distinguished
Wind deflector 14, the left side of the first oblique rotor punching 13 and the second oblique rotor punching are equipped between straight rotor punching 15
Baffle 9 is additionally provided on 16 right sides；In the straight rotor punching 15, the first oblique rotor punching 13 and the second oblique rotor punching 16
Flat key 17 and magnetic shoe slot 18 are equipped on arbor hole, and 18 mirror image of magnetic shoe slot is centrally located the upper side and lower side of axis hole, it is described
Two sides between straight rotor punching 15, the first oblique rotor punching 13 and the central shaft hole and magnetic shoe slot 18 of the second oblique rotor punching 16
It is additionally provided with loss of weight notch 10.
The magnetic shoe slot 18 of the upside misplaces downwards 1.5~2.5mm relative to the punching center of circle；The magnetic shoe slot 18 of the downside
It misplaces upwards 1.5~2.5mm relative to the punching center of circle, the first oblique rotor punching, straight rotor punching and the second oblique rotor
18 outer edge of magnetic shoe slot of punching is provided with pole shoe 19, and 19 radian of pole shoe is 130~145 °.The first oblique rotor punching,
Three screw holes 12 are uniformly arranged on the circumference of straight rotor punching and second 45~Φ of oblique rotor punching Φ 53cm and three dissipate
Hot hole 20, and being equidistantly staggered between screw hole 12 and heat release hole 20, the baffle 9 be equipped with rotor punching position and
The identical screw hole 12 of quantity.The first oblique rotor punching, straight rotor punching and the second oblique rotor punching are adopted from left to right
It is arranged with displaced manner counterclockwise, flat key 17, screw hole 12 and the heat release hole 20 of the first oblique rotor punching 13 are counterclockwise
2.5 ° of disalignment designs, flat key 17, screw hole 12 and the heat release hole 20 of the second oblique rotor punching 16 are inclined clockwise
It is designed from 2.5 ° of center line.
Rotor core may be implemented in this way and form dislocation, realized to stator line by the way of segment fault pole for rotor first
The smoothing processing of circle reduces the data of 5,7 subharmonic, complete machine harmonic wave can be allowed to reach within 5% substantially.With leading among every section of magnetic pole
Aerofoil 14 separates, first is that facilitating heat dissipation, second is that reducing leakage field.And it can shift to an earlier date after being divided into multistage each section of rotor punching riveting
After picking up, magnetic shoe is packed into advance in the magnetic shoe slot 18 of rotor punching, because only that 1 section of magnetic shoe state assembly is will not to go out

Utilization rate.
The wrong pole rotor punching selection of the utility model is oblique 2.5 ° of design.Installation site and oblique 2.5 ° of center line,
Because if skewed stator slot is smooth always to causing electromagnetic data continuity strong, as a result and skewed-rotor can not this
Sample can only be divided into 3 sections or 4 sections, because theoretically number of segment point is more, according to the principle of calculus closer to smooth, but because
The particularity of harmonic wave there is not phase slot number close to every pole when the angle of selection meets (basic electrical angle/segments), this angle is basic
Can match in excellence or beauty with smooth structure, thus the design be in order to balance harmonic wave optimize the degree chosen (24 slot, 2 pole, 3 phase, it is every extremely every
Phase slot number 4).And because when design, pursues balance of voltage etc. the punching can be combined into oblique 10 ° of state with front and back sides, we
Using wrong center of circle design feature, the notch and punching entirety center of circle dislocation 1.5-2.5mm of magnetic shoe are installed in punching for rotor punching design
Range, design can guarantee that punching can continue to use company's tradition magnetic shoe in this way, and will not cause too much non-uniform air-gap because of the wrong heart
Amount increases, and eventually causes performance decline.Punching pole shoe 19 increases practical polar arc using 130--145 ° of polar arc design,
Non-uniform air-gap influence is preferably minimized.And rotor punching two sides are provided with loss of weight notch 10, reduction laminates into the weight after iron core.Punching
Piece there are also screw hole 12, is riveted after facilitating punching press by company's design length on the circumference of Φ 47--- Φ 50, by punching and
Plate washer 9 is riveted together afterwards.
