Abstract

The utility model provides a double-armature double-magnetic field generator comprising a stator and a rotor, which solves the problem of low-speed wind power generation. The generator rotor is a round magnetic disk with Nd-Fe-B magnets with the same number inlaid at both sides, and the magnetic disk is fixed on a principal shaft of the generator to function as the rotor. The generator stator is formed by two generator end covers inlaid with core armatures. The armatures inlaid in the generator stator are divided evenly into three groups according to the quantity of the armatures, wherein each group of armatures are connected in series to form a phase in the mode of 'spanning two adjacent armatures'; in such way, a three-phase armature is formed, terminal lines of which are connected with an external bridge rectifier circuit. The generator saves material and effectively utilizes space; the double-sided magnetic field generates electricity simultaneously in two groups of armatures, thereby the efficiency of power generation is high; and the overall machine is of small size and light weight, is applicable to be used as the host machine of a minitype aerogenerator, and especially applicable to be used as the generator of a wind and solar hybrid power supply device with low power output.

Description

The two magnetic fields of double armature formula generator

Technical field

The utility model relates to a kind of generator, the two magnetic fields of the matching used double armature of especially a kind of air feed power generator formula generator.

The generator that the present wind turbine generator of technical background is used, the operation power generation performance is poor down owing to adapt to low wind speed, is difficult to satisfy weak wind generating requirement, thereby has restricted promoting the use of of wind-driven generator.

Summary of the invention

Have mirror to press this, task of the present utility model just is to provide a kind of can move generating under very low velocity, and is suitable for especially using as the generator of wind-solar complementary type electric supply installation.

This task is achieved in that

The two magnetic fields of a kind of two electricity formula generator, constitute by rotor and stator, it is characterized in that: generator amature is the round disk of a two-sided subsides magnet steel, two cards at this disk, along its circumferential edges, each edge pastes the Nd-Fe-B magnet steel of equal amount, and magnet steel polarity is staggered, after this disk is fixed in generator shaft, promptly become rotor; Generator unit stator is constituted by two generator ' s covers inlaying armature unshakable in one's determination respectively, on the internal face of two end caps, respectively is bumped into the armature unshakable in one's determination of equal amount; The armature that generator unit stator is bumped into is divided into three groups by its quantity, and every group of armature is by " crossing over two adjacent armatures " mode, and series connection becomes one group, the threephase armature that constitutes like this, the external bridge rectifier of its terminal line.

So design, behind the main shaft of packing into as two end caps of stator, the rotor disk just is in two end cap centre positions, thereby constitutes the two magnetic fields of double armature formula generator.After main shaft overhanging end and blade of wind-driven generator fused, blade was subjected to wind drive, and disk is rotated, and constitutes rotating magnetic field, thereby produce the three-phase induced electromotive force in stator armature.This three-phase alternating current behind bridge rectifier, to battery charge, so, promptly constitutes the electric power system of wind-driven generator.

So design, the outstanding advantage that the utility model generator has is: from this generator Structure scheme as can be known, suitable two generators are by a shared main shaft, do the parallel way operation, outwards export three-phase alternating current, so economical with materials, and effectively utilize the space, two-sided magnetic field produces electric energy simultaneously in two groups of armatures, the generating efficiency height, machine volume is little and in light weight, thereby is suitable for doing very much the small-sized wind power generator main frame, especially is suitable for the generator use as the wind-solar complementary type electric supply installation of low electric energy output.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described further:

1, embodiment 1 is the two magnetic fields of double armature formula generators:

As shown in Figure 1: this generator is made of front end housing 1, rear end cap 2, armature 3, armature core 4, circle disk 5, magnet steel 6, main shaft 7, bearing 8 and fixed screw 9.Generator amature is the round disk 5 that a two-sided edge pastes magnet steel 6, and promptly in two cards of this disk 5, along its circumferential edges, each 24 of edge subsides, disk two sides amount to and stud with 48 Nd-Fe-B magnet steels; After disk 5 usefulness screws 9 fixedly are loaded on main shaft 7, promptly become the rotor of generator.

The stator of generator is made of front end housing 1 and rear end cap 2, with two pairs of bearings 8, is loaded on the main shaft 7; At the inner edge of two end cap, respectively be bumped into 18 unshakable in one's determination 4 armature 3 is housed; Every 18 armatures 3 that end cap is interior, by connecting mode shown in Figure 2, be that per 6 armatures 3 are one group, by " crossing over two adjacent armatures " mode, series connection becomes a phase, so the threephase armature that constitutes in two end caps, behind its terminal line parallel, the three-phase alternating current of being exported, external bridge circuit rectification just can be to battery charge.

Embodiment 2 is for being equipped with the wind-solar complementary type street lamp of the two magnetic fields of double armature formula generator;

As shown in Figure 3, this wind-solar complementary type street lamp is by 1 60W solar panels 12, with LED make the light fixture 13 of light source, wind-driven generator 14 and vertical rod 15, the pedestal 16 of making driving host with the two magnetic fields of the utility model double armature formula generator form.
