Part, coil straight line portion support；It is characterized in that：The rotor punching, damping sheet are connected by flat key with rotating shaft, damper bar,
Locating bar is fixed in the damping hole of rotor punching and locating bar hole, and rotor punching, damping sheet, damper bar, positioning bar construction turn
It is sub unshakable in one's determination, rotor core is formed by entirety with damping plate weld by the half slot welding in rotor punching and damper bar；Turn
Subcoil is directly wound in rotor core, there is insulating paper, coil straight line portion between rotor coil straight line portion and rotor core
Rotor coil is supported and forms axial ducts by support；Casing pipe sleeve is arranged on rotor in locating bar two ends, coil-end brancing
Two ends unshakable in one's determination, by rotor coil ends and rotor core overhang insulation, while turning rotor coil by coil-end brancing
Crook forms arc transition, and forms a radial passage；Bracer component is fixed between the coil of the two poles of the earth, by coil straight line portion
It is fixed；Two gimbals are respectively bolted to the two ends of locating bar.
Described sleeve pipe is the outer square shape of inner circle, is made of insulating materials, and sleeve pipe insulate rotor coil ends and locating bar.
It is fixed on during the rod coiling of radial passage in the middle of rotor coil ends and forms other radial passage.
The rotor punching is overall chip architecture, and cylindrical is off-centre operation, per the two poles of the earth between have a half slot, two it is square
Groove, half slot is used for welding being integrally formed rotor core, and square groove is used on fixed coil straight line portion support, rotor punching
Also damping hole and locating bar hole.
The gimbal is circular configuration, has gimbal fixing hole and Balance Iron mounting hole above, gimbal is existing will be fixed
The effect that position rod is connected, plays the role of to fill Balance Iron again.
The rotor core is without pressing plate and clamping screw.
The quantity of the radial passage and radial passage rod can also change according to actual needs.
The solution have the advantages that：1st, rotor core is without pressing plate and clamping screw, and core construction is simple, and cost is low, together
When shorten rotor coil ends length, not only reduce the consumption of copper cash, also reduce the centrifugal force of rotor coil ends, carry
The high rigidity of rotor coil ends, makes the stability of rotor coil ends, reliability higher；2nd, radial passage and axial ducts
The radiating effect of rotor is improved, the temperature rise of rotor is reduced, the cost performance of generator can be improved；3rd, the entirety of eccentric structure
Rotor punching can improve the voltage regulation factor of generator；Interpolar concave shaped arc structure makes that between the two poles of the earth axial wind can be formed
Road；Semicircular welding groove is placed between the two poles of the earth, can not only make welding unshakable in one's determination integral but also will not have an impact to coil, it is to avoid
Weld seam causes on pole body pole insulation to destroy and make the hidden danger of rotor coil over the ground；Integral rotor-piece makes rotor core
Make simple and quick, production efficiency is high；4th, the outer square casing of inner circle can be not only enclosed on locating bar securely, and and rotor
End turn has good contact surface, and end turn is unlikely to deform, reliable and stable；5th, the gimbal of two ends of rotor connects locating bar
Integrally, the centrifugal force produced when motor rotates at a high speed per pole end turn is cancelled out each other by gimbal, alleviates centrifugal force
To the pressure of locating bar, the reliability of rotor tip is improved, can also do locating bar is smaller, save material cost；
Installation Balance Iron is convenient and swift in gimbal, and technique is simple.
