Specific embodiment
Refer to shown in Fig. 2, Fig. 3 and Fig. 4, a kind of electricity generation and electric welding all-in-one rotor line shell 100, including coil 1, line shell sheet
Body 2 and magnet steel 3, the line shell body 2 include four pole segments 21, eight coil grooves 22 and a central bore 23, the eight coils groove
22 left and right sides for being mounted on pole segment 21 described in two-by-two；Inside edge per the pole segment 21 extends perpendicularly outward, shape
Into two fixed columns 24, the free end per the fixed column 24 is equipped with a recess 241 and a crook 242, and the crook 242
Set towards coil 1.The setting of the recess 241 and crook 242, changes the Wugou of lead-out wire fixed column 24 end to end of coil 1
The traditional design method of shape structure, as long as by the lead-out wire of coil 1 (not shown) after recess 241 and crook 242 twine a circle
Connecting pin 41 with collector ring 4 is welded, and such lead-out wire would not be deviate from from fixed column 24 and occur getting rid of disconnected phenomenon, make coil 1
Lead-out wire energy fixation end to end, improves the reliability of product quality.The coil groove 22 of adjacent two pole segment 21 90 ° of neighbours each other
Connect.
Referring again to Fig. 2, Fig. 3 and Fig. 4, a fan blade 25, the wind are provided between the coil groove 22 of adjacent two pole segment 21
Leaf 25 is located at the lateral surface 2b of line shell body 2, and the free end of the fan blade 25 caves inward, and forms a groove 251.Fan blade 25
Set, motor internal radiating effect will be further improved, larger effect is played to reducing temperature rise, improving efficiency；It is described recessed
The setting of groove 251, for coil between pole and pole 1 interconnection (not shown) by with positioning.It is outer per the pole segment 21
Edge is vertically provided with two square blades 26, and the cross section per the square blade 26 is respectively provided with a side long 261 and a short side 262,
And the short side 262 of the square blade 26 is set towards coil 1.It is so designed that, the sagittal plane of the square blade 26 is wider, but side
Shape blade 26 is smaller with the end contact face of coil 1 so that the radial strength of square blade 26 is high, can prevent the end of coil 1 in centrifugation
Outwards thrown away under power effect, while making the lateral surface of the end of coil 1 substantially exposed in atmosphere in order to radiate, and work as rotor
During operating, square blade 26 can play a part of fan, improve the result of ventilating heat dissipation of motor internal.Per the pole segment 21
Outer end be respectively provided with a flat side 211, the middle part of the flat side 211 is provided with a recess matched with the magnet steel 3
