Asymmetric salient pole generator rotor punching sheet structure

Abstract

The invention relates to a rotor punching sheet structure of an asymmetric salient pole generator. The rotor punching sheet structure comprises a circular rotor punching sheet body, a shaft hole, key grooves, fan-shaped notches and T-shaped sheets, each T-shaped piece comprises a T-shaped piece connecting section and a T-shaped piece working section, the width of the T-shaped piece working section is larger than that of the T-shaped piece connecting section, at least two series rod mounting holes are formed in each T-shaped piece connecting section, the series rod mounting holes are arranged in a bilateral symmetry mode with the radial center line of the T-shaped piece connecting section as the symmetric line, and damping strip mounting holes are formed in the T-shaped piece working sections. A steering arm mounting hole is formed in the working section of the T-shaped sheet corresponding to the inner side of the damping bar mounting hole; the length of the forward rotation end of the T-shaped piece working section is smaller than that of the reverse rotation end of the T-shaped piece working section. Through the asymmetric structure of the rotor punching sheet, the harmonic wave of the generator is eliminated; the stator or rotor skewed slot is prevented from being manufactured, the manufacturing difficulty is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a punching structure of a salient pole generator, in particular to an asymmetrical salient pole generator rotor punching structure. Background technique [0002] In order to weaken the harmonics of the generator, it is usually necessary to set up a chute; there are two ways of the chute: the stator chute and the rotor chute. [0003] In the prior art, the stator slant needs to be inclined at the same time as the stator coil, which causes inconvenience in operation and reduces the working efficiency per unit time. The rotor chute will have the same problem. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an asymmetrical salient pole generator rotor punching structure which has a simple structure, can weaken harmonics, and does not require inclined slots on both stator and rotor blades. [0005] According to the technical solution provided by...
