Vertical shaft type low-speed magnetic levitation multistage generator

Abstract

The invention discloses a vertical shaft type low-speed magnetic levitation multistage generator, which comprises power generation mechanisms and a vertically arranged rotating shaft, and is characterized in that the power generation mechanism sequentially comprises a bottom fixed disc, a rotating disc and a top fixed disc which are coaxially arranged from the bottom up, the rotating shaft sequentially penetrates through the top fixed disc, the rotating disc and the bottom fixed disc, the rotating shaft is fixedly connected with the rotating disc, and the rotating shaft is rotatably connected with the top fixed disc and the bottom fixed disc; a purpose that power generation can still be realized under a low-speed condition is achieved through a structure form of one-support-three in which a first coil winding and a second coil winding are respectively set at the upper part and the lower part of each excitation magnet and third coil windings are set at the periphery of the rotating disc; and one the other hand, the rotating shaft simultaneously drives a plurality of power generation mechanisms to generate power, so that a purpose of power generation can also be realized under a lower-speed condition.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a vertical-shaft low-speed magnetic levitation multistage generator. Background technique [0002] The structure of a conventional generator mainly includes a rotor and a stator. A winding is arranged on the stator, and a magnet is installed on the rotor. Then, an external force is used to drive the rotor to rotate, so that the winding of the generator generates an induced electromotive force, thereby outputting power. Between the magnet and the winding There will be a certain magnetic force between them, so the rotor needs to be given a certain speed before the rotor can start. At present, the speed of most generators is above 500 rpm, or even higher such as 1500-2800 rpm. start generating electricity. The bearings of existing motors are divided into thrust bearings and radial bearings according to their functions, and are divided into sliding bearings and rollin...

AI Technical Summary

Problems solved by technology

Among all kinds of bearings, there are the following problems. First, energy loss due to mechanical friction; second, bearing damage caused by temperature rise; third, frequent maintenance and replacement due to friction and wear, and a large amount of heat will be generated during high-speed rotation. Causes wear and even deformation of the rotor shaft, which seriously affects the service life of the generator
