Single-phase generator for illumination

Abstract

The invention discloses a single-phase generator for illumination. The generator comprises a generator shell, a stator assembly arranged in the generator shell and a mover assembly moving relative tothe stator assembly. The stator assembly comprises a stator core and a plurality of stator coils installed on the stator core, the mover assembly comprises a moving shaft, a plurality of mover magnetic poles are evenly distributed outside the moving shaft, the moving shaft drives the mover magnetic poles to move relative to the stator coils, and a length of the mover magnetic poles installed on the moving shaft is larger than that of the stator core. The single-phase generator for illumination, which is light in weight and long in service life, is provided for an upper illumination surface ofa bicycle.

Description

technical field [0001] The invention belongs to the field of generators, and more specifically relates to a single-phase generator for lighting. Background technique [0002] The linear generator is an electromechanical energy conversion device that can directly convert mechanical energy into electrical energy output. Compared with the traditional rotary generator, this power generation device reduces the intermediate links of energy conversion, and has the advantages of simple structure, small mass and volume. It can be widely used in linear power generation systems, such as free piston power generation systems, direct drive wave power generation systems, oscillation power generation systems, etc. [0003] Linear generators can be divided into moving coil type and moving magnet type according to the form of the mover. The coil acts as the mover to move, and the permanent magnet is fixed. The linear generator is called a moving coil type linear generator, and the permanent m...

AI Technical Summary

Problems solved by technology

At present, although the linear generator can obtain a higher power density, it still has the following disadvantages: the structure is relatively complex, which is not conducive to manufacturing and assembly; the loss of the linear generator is high, especially the high iron loss, which leads to the loss of the generator The efficiency is low, and the power generation efficiency needs to be further improved

However, if the existing battery is installed, the small battery has less storage capacity and the use time is short, and the large battery weighs a lot, which brings a burden to the rider.
