Problems solved by technology

[0003] 1. During the long-term rotation of the brush, it will cause wear, reduce the working efficiency of the generator and shorten the service life of the generator
[0004] 2. The powder from the brush wear will cause a short circuit to the brush and the internal electronic components of the motor
[0005] 3. The brush will generate heat and sparks during the wear process, which will accelerate the aging of surrounding components and cause fires to vehicles using fuel

Abstract

The invention discloses a brushless claw-pole power generator. The brushless claw-pole power generator comprises a shell, an excitation winding is peripherally wound on an excitation iron core arranged in the shell, and a stator winding is fixed onto the inner wall of the shell corresponding to the excitation winding. A left claw pole and a right claw pole are in opposite arrangement and externally sleeve the excitation iron core in the shell, left and right transmission shafts are fixedly arranged at centers of the outer end faces of the left and right claw poles respectively, the right transmission shaft penetrates through the right end of the shell, and a transmission wheel is fixedly mounted at the penetration-out end of the right transmission shaft. Annular nonmagnetic rings are mounted on the outer end faces of the left claw pole and the right claw pole respectively. The brushless claw-pole power generator has the advantages that abrasion caused by an electric brush is avoided, service life of the power generator is prolonged, and the problems of short circuit, aging of parts, fire hazards and the like are prevented.

Description

technical field [0001] The invention relates to the field of generators, in particular to a brushless claw pole motor. Background technique [0002] The existing claw pole generator mainly includes the stator on the shell and its inner wall, the rotor and the excitation coil on it, and the claw poles. A brush is installed between the shell and the rotor. The excitation coil is energized to form a magnetic flux on the claw poles at both ends of the excitation coil. During operation, under the drive of the vehicle's power device, the magnetic field on the rotor claw pole and its surface starts to rotate, and the stator winding cuts the magnetic induction line to generate current to the outside. The claw pole generator with this structure has the following disadvantages: [0003] 1. During the long-term rotation of the brush, it will cause wear, reduce the working efficiency of the generator and shorten the service life of the generator. [0004] 2. The powder from the brush ...
