Technical background
At present, in published pair of permanent magnet rotor power generator, not yet mention the fast requirement of joining between two p-m rotors, and when generator assembles, require to carry out pre-determined bit operation.The type generator is because initial loading timing coil windings stator is not identical with rotating speed with two p-m rotor position relationships, and makes generating efficiency have certain difference, more cannot realize generating efficiency and maximize.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of two permanent magnet rotor power generators of joining speed variator and being subject to assembly constraint that comprise are provided.
Realizing technical scheme of the present invention is: in two p-m rotor class rotor machines, except central shaft, permanent magnetism the first rotor, permanent magnetism the second rotor be positioned at two coil windings stators between rotor, also comprise a gear drive and join speed variator; Conventionally central shaft comprises hollow path, and is connected and fixed with peripheral strutting piece, and coil windings stator is connected and fixed by strutting piece and central shaft, and electric power is transferred to generator ancillary equipment via central shaft pipeline again along the strutting piece of connecting stator.
The technology of the present invention feature: the gear ratio value that speed variator is joined in gear drive just in time equals the ratio of the first rotor permanent magnet quantity and the second rotor permanent magnet quantity, to meet the product of the first rotor permanent magnet quantity and rotating speed, equal the product of the second rotor permanent magnet quantity and rotating speed, or the first rotor permanent magnet quantity equals the product that speed variator gear ratio value is joined in the second rotor permanent magnet quantity and gear drive; Driving source, when input block is driving the first rotor to rotate, and is joined speed variator by gear drive again and is driven the second rotor to rotate backward; Simultaneously, when generator assembles, the magnetic pole of two p-m rotors that in requirement stator, each coil of homophase is corresponding has the feature of relative mirror image symmetry, meet two p-m rotors always relative at the center of stator winding coil generation " N-S " or " S-N " magnetic pole, and empty place generation " N-N " or " S-S " magnetic pole is relative between stator winding two adjacent windings, so that in generator amature rotation process, magnetic flux and variation rate of magnetic flux by each coil all can reach maximum, thereby obtain best generating effect.
In technical solution of the present invention, the relative position relation of the first rotor, the second rotor and coil windings stator has two kinds of situations, and the one, concentric structure relation, the first rotor and the second rotor are specially the relation of external rotor and internal rotor like this; The 2nd, parallel coordinate structure relation on axle, the first rotor and the second rotor are specially left rotor and the sub relation of turning right like this.
The advantage of generator of the present invention is: when generator works, can guarantee all to reach maximum by magnetic flux and the variation rate of magnetic flux of each coil, thereby obtain best generating effect, extensively applicable various generating environment.
