Self-excitation single-phase generator

Abstract

The invention discloses a self-excitation single-phase generator. The invention particularly relates to the technical field of excitation generators. The generator comprises a collecting ring, a rotorshaft, a front claw pole, a rear claw pole, a magnet yoke and claw pole fingers, the sizes of the claw pole fingers on the front claw pole and the rear claw pole are sequentially reduced in the direction of the opposite faces of the front claw pole and the rear claw pole, a distance groove matched with the size of each claw pole finger is formed between every two claw pole fingers, and a connecting groove and a connecting plate which enable the opposite ends of the claw pole fingers on the front claw pole and the rear claw pole to be connected at intervals are arranged between the claw pole fingers. According to the invention, the opposite ends of the claw pole fingers on the front claw pole and the rear claw pole are arranged at intervals, and the magnetic conductivity generated by permanent magnets on the claw pole fingers generates a magnetic conduction space in the interval grooves, so that the stability of the magnetic conductivity and no dead angle of the inverted conductor space of the permanent magnets is further ensured; while the permanent magnets in the claw pole fingers are detachably installed, compared with a traditional mode that the permanent magnets are directly attached to the claw pole fingers for installation, better fixing strength and stability are achieved.

Description

technical field [0001] The invention relates to the technical field of excitation generators, more specifically, the invention relates to a self-excitation single-phase generator. Background technique [0002] A generator is a mechanical device that converts other forms of energy into electrical energy. The generator excitation system is a general term for the power supply and its ancillary equipment that supply the excitation current of a synchronous generator. It generally consists of two main parts, the excitation power unit and the excitation regulator. [0003] The current self-excited single-phase generator rotor has permanent magnets embedded between the front and rear claw poles to increase the magnetic conductivity of the claw poles, but the position of the permanent magnets is unstable and directly affects the performance of the product, which increases the difficulty of assembly. Contents of the invention [0004] In order to solve the above technical problems,...
