Description

Relatively rotate the formula generator

Technical field

The utility model relates to a kind of generator, especially relates to a kind of generator that utilizes wind power generation.

Background technology

Its structure of the wind-driven generator of prior art roughly is such: be provided with axle, rotor and stator in the shell of generator, be provided with steering gear between rotor and flabellum, flabellum is generated electricity by coil cutting magnetic line by the rotor of steering gear driven rotary.The required rotating speed height of this structure generator needs higher wind speed, and generating efficiency is low.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provides a kind of higher wind that do not need also can normal power generation and high stator, the relative rotation of rotor formula generator of generating efficiency.

Technical solution of the present utility model is achieved in that and relatively rotates the formula generator, by casing, axle, stator, rotor, coil, output line is formed, be provided with steering gear between rotor and rotor blade, rotor blade is by the rotor of steering gear driven rotary, it is characterized in that, described rotor axial cutaway view is a concave-convex, described stator shaft orientation cutaway view is the convex concave for matching with rotor also, be connected with the stator flabellum in the stator termination, the stator flabellum is greater than rotor blade, the stator flabellum is opposite with the rotor blade direction of rotation, it is right to fix a plurality of rotor magnetic poles on rotor concave-convex inner chamber, on stator, be provided with coil windings, between rotor and stator, be provided with the brush ring, at stator, rotor and between centers are provided with stator bearing and rotor bearing, at stator, be provided with stator outer bearing and rotor outer bearing between rotor and casing, the rightabout rotation of rotor and stator.

The beneficial effects of the utility model are: rotor can be fixed a plurality of rotor magnetic pole logarithms on the convex concave inner chamber, has reduced the rotating speed of generator.The fan page or leaf on both sides is under the wind-force effect, and rotor is the clockwise direction rotation, and stator is rotation counterclockwise, by relatively rotating of rotor and stator, has increased the number of times of electromotive force alternation each second, makes full use of wind-force, improves generator for electricity generation efficient.According to the relation of Φ=BS, the invention of this structure increases main flux induction B and magnetic circuit sectional area s, obtains big as far as possible induced electromotive force in stator winding, improves generating efficiency.The magnetic circuit that fixing magnetic pole produces on the rotor, abundant cutting magnetic line in the lower coil on stator.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail, relatively rotate the formula generator, by casing (6), axle (5), stator (2), rotor (1), coil, output line (12) is formed, be provided with steering gear (7) between stator (1) and stator flabellum (3), stator flabellum (3) drives stator (1) rotation by steering gear (7), described stator (1) axially cutaway view is a concave-convex, described stator (1) axially cutaway view also is the convex concave that matches with rotor (2), be connected with rotor blade (4) in rotor (2) termination, (3 direction of rotation are opposite with the stator flabellum for rotor blade (4), it is right to fix a plurality of rotor magnetic poles on rotor (2) concave-convex inner chamber, on stator (1), be provided with coil windings, between rotor (2) and stator (1), be provided with brush ring (11), in stator (1), be provided with rotor bearing (9) and stator bearing (10) between rotor (2) and axle (5), in rotor (2), be provided with rotor outer bearing (8) and stator outer bearing (13) between stator (1) and casing (6).At convex-concave rotor (2) the outer shaft upper rotor part flabellum (4) of front under the wind-force effect under the steering gear restriction, drive concavo-convex rotor (2) by rotor bearing (9) and rotor outer bearing (8) and do the clockwise direction rotation, the convex-concave stator (1) of back is done rotation counterclockwise under the wind-force effect.Because relatively rotating of concavo-convex rotor (2) and convex-concave stator (1) reduced the rotary speed of generator relatively.

More magnetic pole logarithm is installed on the rotor, can be reduced the rotary speed of generator.
