Abstract

The utility model discloses a composite dynamo magneto, comprising a rotor, a stator and a rotation shaft. The rotor is fixed on the rotation shaft and the stator is provided with a coiled winding. Both the rotor and the stator are of vertical plate-like structure. A plate-like disc of the rotor is embedded with a permanent magnet passing through two sides of the plate. The two stators are positioned on two sides of the rotor and connected together by a lead screw. The coiled winding of each stator corresponds with the permanent magnet of the rotor. The utility model is a portable dynamo magneto which saves energy and protects environment, suitable for family, unit, personal and emergency use. The rotor can be driven to generate power by a variety of driving methods such as manpower, wind power, water power or gasoline, diesel engine and the like. The utility model adopts a vertical multi-group composite form, simple to install and easier to design the installed capacity as required. The utility model is extremely convenient to fix, assemble, disassemble and repair, with wide developing space and strong practicability.

Description

The composite type permanent magnet generator

One, technical field

The utility model belongs to the dynamic power technical field, is specifically related to a kind of composite type permanent magnet generator.

Two, background technology

The generator great majority that use also all are traditional squirrel-cage generators at present, and on version, it is only paid attention to laterally, does not pay attention to vertically, and it is bigger that machine is taken up an area of, and do not utilize the space fully.Along with the development of permanent magnetic material, the particularly development of high energy product rare earth permanent-magnetic material has greatly promoted to replace with permanent magnet excitation the development of electric excitatory motor technology.Thus, little, the light weight of various volumes, energy-efficient permanent magnet generator just arise at the historic moment.The permanent magnet of permanent magnet generator is magnetic source in generator, is again the part of magnetic circuit, and generator need not the excitation winding of general conventional electric generators, does not need outside energy can keep its magnetic field after making, and is a kind of energy-conserving product.Permanent magnet rotor structure has been removed from and has been produced the mechanical loss that rubs between the required exciting power in rotor field and carbon brush, the slip ring, makes the generator efficiency greatly to improve.Permanent magnet generator of the prior art also exists efficient not high enough, inconvenient problem with use.

Three, summary of the invention

The purpose of this utility model provides a kind of efficient, energy-conservation, easy-to-use composite type permanent magnet generator.The technical solution adopted in the utility model is: the composite type permanent magnet generator comprises rotor, stator and rotating shaft, rotor is fixed in the rotating shaft, winding coil is arranged on the stator, its rotor and stator all are vertical platy structures, be inlaid with the permanent magnet that runs through the plate both sides on the tabular disk of rotor, two stators are in the rotor both sides, are linked together by screw mandrel, and the winding coil on each stator is corresponding with the permanent magnet of rotor.

The utility model is a kind of portable permanent generator that is suitable for the emergent and energy-saving and environmental protection of family, unit and individual's use, can pass through multiple type of drive such as manpower, wind-force, waterpower or vapour, diesel engine etc. and drive the rotor rotation generating.The utility model adopts vertical many group combining forms, installs simply, designs installed capacity according to demand easilier.Not only can save energy environmental protection, but also can meet an urgent need, more reasonable, more practical.The stator of generator, rotor all adopt adjustable connection, and fixing, dismounting, maintenance are very convenient, can make the rotor field maximum effect under the prerequisite of safety on stator winding, improve generating efficiency.Delicate structure, the stator and rotor size is ultra-thin, and the utility model both can constitute a ultra-thin single generator by a rotor and two stators, also can constitute the composite type permanent magnet generator by a coaxial N rotor and 2N stator.The stator and rotor thickness of single generator is no more than 6CM, on the axle of length 30CM stator and rotor more than three groups can be installed, and power can improve more than three times; Expansion axial length dress N group stator and rotor can promote the N times power, and the utility model development space is wide, practical.

Five, embodiment

The composite type permanent magnet generator comprises that stator 4,

rotor

6 and 4, two stators 4 of 3, one rotors of rotating shaft, 6 corresponding two stators are in rotor 6 both sides.Rotating shaft 3 is low magnetic stainless steel axle, rotor 6 and stator 4 all are vertical thin sheet form, all adopt non-magnet material making such as epoxy resin board, be inlaid with the permanent magnet 7 of a plurality of run-through boards both sides on the tabular disk of rotor 6, permanent magnet 7 is upwards arranged multilayer in the footpath of rotor discs, in a circumferential direction, adopt the arrangement mode of the N utmost point, the extremely symmetrical equidistant alternate layout of S.Permanent magnet 7 corresponding winding coils 5 with rotor 6 are arranged on each stator 4, and the two poles of the earth of permanent magnet 7 act on the winding coil 5 of both sides stator 4 simultaneously.In same rotating shaft 3, many group rotors 6 and stator 4 can be installed.Rotor 6 and rotating shaft 3 adopts flanges 8 to be connected, and flange 8 and rotating shaft 3 are fixed by jackscrew, and flange 8 and rotor 6 usefulness screws are fixed.This connection is convenient to regulate the position of rotor 6 in rotating shaft 3.The stator 4 of rotor 6 both sides links together by the stainless steel screw mandrel 2 of low magnetic conduction, and fixing by nut 9, the outer end of screw mandrel 2 is connected with boxboard 1, and there is axis hole 10 at the center of boxboard 1.The distance of stator 4 relative rotors 6 can be adjusted, and makes the rotor field maximum effect on stator winding 5 under the situation that guarantees safety, improves generating efficiency.This structure also is convenient to the maintenance and the replacing of stator simultaneously.Winding connection adopts grouping to connect, and is furnished with the rectifier bridge rectification.In the rotating shaft 3 drive is installed, adopts the special axle sleeve of changeable type, can join multiple transmission mechanisms such as chain, gear, impeller, blade, belt pulley, can adjust gearratio as required simultaneously, play synergistic effect.
