Abstract
Disclosed is a double-air gap solenoid type winding permanent magnetic electric machine. The iron cores of winding armature windings are made up of magnetic strip-shaped silicon sheets coiling along the circumferential direction. The armature windings bind or sheath every pole group to the iron core according to the rule of bi-phase or three-phase in space with enamel conductors, and the winding conductors on both sides of the iron core and radially distributed are active conductors. The main field of the electric machine is provided by Nd-Fb-B permanent magnet, respectively equipped at both sides of the armature windings, alternatively arranged according to N or S pole in the cirumferential direction, and is fixed to the surface of the magnetic metal body. The magnetic direction is perpendicular to the active conductors of the armature. The magnetic electric machine of the utility model has simple and compact structure, and high effective material utilization, so the radial dimension is largely reduced, and the weight of the motor is reduced. The utility model is especially suitable to the desigh of multi-stage high capacityelectric machine, such as high capacity wind-driven electricity generator, and low speed hydro-driven electricity generator.
Description
Affiliated technical field
The utility model relates to a kind of pair of air gap solenoid type winding magneto, and promptly armature winding is wrapped on the conducting magnet core as solenoid, and both sides permanent magnet and same armature winding form two air gap solenoid type winding magnetoes of air gap respectively.
Background technology
Existing magneto, adopt has the teeth groove structure more on the iron core, armature winding is embedded in and wherein constitutes conventional winding arrangement mode, perhaps adopt slotless or planographic winding, these all make magneto be restricted in the application in some fields, as the restriction on the capacity, the restriction on the structural member intensity and the restriction on the application space or the like.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the efficient height, and the novel permanent magnetic motor that stock utilization is good particularly can be designed more jumbo magneto under the situation that the axial-radial size does not increase.Can be designed to disc type axial air-gap magnetic field structure as required, also can be designed to cylindrical shape radial air gap magnetic field structure.
The technical scheme that its technical problem that solves the utility model adopts is: the iron core of winding armature winding is along the circumferential direction reeled by the strip silicon steel sheet of magnetic conduction or is overrided to form, and can leave teeth groove on iron core two end faces radially, also can not tooth punching groove.Armature winding is spatially then organized each utmost point mutually by two-phase or three-phase rule and is twined or be enclosed within on the iron core, armature winding is formed by the enamelled wire coiling, the winding conductor that the iron core both sides radially distribute is an active conductor, dipping lacquer curing becomes one iron core and winding then, the main field of described motor is provided by the Nd-Fe-B permanent magnet, place the both sides of armature winding respectively, both sides permanent magnet opposed same polarity is relative, along the circumferential direction alternately arrange and be fixed in the metal body surface of magnetic conduction by N, the S utmost point in each side, its magnetic direction is perpendicular to the active conductor of armature.Under the two-phase winding situation, a phase (or starting winding) series capacitor therein.
The utility model motor can be designed more jumbo magneto under the situation that the axial-radial size does not increase, and it is simple and compact for structure, effective stock utilization height, especially more be applicable to multipole large-size machine, solved this type of motor well in problem limited on the capacity, on the structural member intensity and on the application space.

Embodiment
Fig. 1 axis (1) links to each other with stator support (5), stator core (7) is fixed on the stator support (5), stator core (7) is along the circumferential direction reeled by the thick strip silicon steel sheet of 0.35mm and is formed, stator core in the present embodiment (7) does not have the tooth punching groove, every armature winding (8) that extremely plays is wrapped on the stator core (7) with the three phase winding rule sequence arrangement of enamelled wire by A phase-negative C phase-B phase-negative A phase-C phase-negative B phase, dipping lacquer then, armature winding (8) and stator core (7) are cured as one, the output of armature winding (8) is drawn by the axle (1) of hollow, the winding conductor that stator core (7) both sides radially distribute is an active conductor, permanent magnet (4) is N as shown in Figure 3 along the circumferential direction, S utmost point arranged alternate, and be fixed in the rotor yoke (3 of magnetic conduction, 6) on, and make the active conductor of the magnetic direction of permanent magnet perpendicular to armature, the silicon steel sheet magnetic conduction direction that makes coiling stator core (7) is for circumferential, left and right sides rotor yoke (6,3) permanent magnet on is with the identical polar positioned opposite, left and right sides rotor yoke (6,3) fuses by connector (9) and constitutes a complete rotor.
Have only the right side that bearing (2) is housed in the present embodiment, can left-right symmetric be installed by bearing as required.Stator core can put in order the garden and reel and to form, and also can make according to arts demand and laminate split-type.
The utility model embodiment explanation can be designed more jumbo magneto under the situation that the axial-radial size does not increase, the motor that designs same capability in other words can dwindle radial dimension, therefore say that the utility model is particularly suitable for the design of multipole large-size machine, as wind-driven generator, slow-speed of revolution hydroelectric generator.Not increasing substantially under the situation that axial dimension and assurance exert oneself, can dwindle its radial dimension greatly, reduce motor weight, and it is simplified the structure, this has very large practical value on actual engineering.
