Brushless claw pole generator

Abstract

The invention relates to a brushless claw-pole generator. The claw-pole generator has no abrasion caused by brushes, prolongs the service life of the generator, and prevents short circuits, component aging, and fires from occurring. It includes a casing, and an excitation core is arranged in the casing, and a circumferentially wound excitation winding is arranged on the excitation core, and a stator winding is fixed on the inner wall of the casing corresponding to the excitation winding. There are two oppositely arranged left claw poles and right claw poles located on the outer surface of the excitation core in the body, and a left and right transmission shaft is fixed at the center of the outer end faces of the left and right claw poles, and the right transmission shaft passes through Out of the right end of the housing, a transmission wheel is fixedly installed at the exit end of the right transmission shaft; ring-shaped non-magnetic rings are respectively placed on the outer end faces of the left claw pole and the right claw pole.

Description

Technical field [0001] The invention relates to the field of generators, in particular to a brushless claw pole motor. Background technique [0002] Existing claw-pole generators mainly include a casing and a stator on its inner wall, a rotor, and an excitation coil and claw poles on it. Brushes are installed between the casing and the rotor. The excitation coil is energized to form a magnetic flux to the claw poles at both ends of the excitation coil. During operation, the magnetic field on the rotor claw pole and its surface starts to rotate under the drive of the vehicle's power unit, and the stator winding cuts the magnetic induction line, thereby generating an external current. The claw-pole generator of this structure has the following disadvantages: [0003] 1. In the process of long-term rotation, the brush will cause wear, reduce the working efficiency of the generator and shorten the service life of the generator. [0004] 2. The abraded powder of the brush will short-cir...

AI Technical Summary

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
