The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, a kind of construction rotor of inductive impulse generator, including shaft 1 and shielding compensate sleeve 5, turn
For axis 1 through connection composite material rotor yoke 2, composite material rotor yoke is surrounded with conductiving metal strip 3 for 2 one weeks, and conductiving metal strip 3 wraps
Circumferential conductor metal item 31 and axial conductor metal item 32 are included, circumferential conductor metal item 31 is made of multiple endless metal items, week
Conductor 801 metal strip 31 is parallel with end transition boss 4, and axial conductor metal item 32 is made of multiple cylindricality metal strips, is axially led
Body metal strip 32 is parallel with shaft 1, and circumferential conductor metal item 31 is around the both ends for being connected to axial conductor metal item 32, Zhou guide
Body metal strip 31 is symmetrical with the center line of axial 32 length direction of conductor metal item, and conductiving metal strip 3 is sleeved on shielding compensation sleeve 5
The length of inside, axial conductor metal item 32 is consistent with the shielding compensation length of sleeve 5, conductiving metal strip 3 and shielding compensation set
Cylinder 5 is overall structure, and faradic path, shielding compensation are provided together with shielding compensation sleeve 5 when motor stabilizing is run
Sleeve 5 is using structure made of smooth surface aluminum material, and smooth surface aluminum material cylinder plays vortex in pulsed discharge
The effect of current carrying layer, composite material rotor yoke 2 are made using the winding of carbon fiber bandage, and shielding compensation sleeve 5 uses interference
It is bonded and is integrated with epoxy resin with composite material rotor yoke 2 after cooling, the both ends of shielding compensation sleeve 5 are connected with end transition
Boss 4, end transition boss 4 are arranged to the cylindrical structure to match with shielding compensation sleeve 5, the work of end transition boss 4
