Description
Technical field
The present invention relates to a kind of generator, specifically a kind of single-wire multipole small-size external rotor variable frequency generator stator winding.
Background technology
Existing small generator all is an internal rotor, and internal rotor drags rotation by power, and excitation produces magnetic field in the rotating shaft, perhaps adorns permanent-magnet steel in the rotating shaft, and the generating winding embeds in the enclosure on the chamber.
Summary of the invention
The objective of the invention is to seek a kind of single-wire multipole small-size external rotor variable frequency generator stator winding, the magnetic field of this stator winding is multipole, and coil is a single line when rolling off the production line, not according to conventional method coiled multiturn coil, to reduce the metal consumption.
According to technical scheme provided by the invention, stator is arranged in the enclosure, described stator is formed by some silicon steel sheet mutual superposition, the stack direction of silicon steel sheet and the parallel axes of described shell; The wire casing of some radial arrangement is set on stator, in described wire casing, generator windings is arranged; Described wire casing is distributed in the outer rim of stator radially equably, and the outer end of wire casing is opened wide; The some blocks of permanent-magnet steels that the inwall that is installed on described shell is arranged between described stator and described shell.
In described permanent-magnet steel, the polarity of the adjacent both ends of adjacent two blocks of permanent-magnet steels is opposite.In described motor windings, what be positioned at the wire casing bottom is a phase line, and what be positioned at the wire casing middle part is the b phase line, and what be positioned at the wire casing outer rim is the c phase line; Every group of phase line forms by 1 continuous enamelled wire.The quantity of the wire casing on the described stator is 2: 1 or 3: 1 with the ratio of the quantity of described permanent-magnet steel.The width of described wire casing is slightly larger than the external diameter of single enamelled wire, and the enamelled wire in the wire casing on the generator windings is that single multilayer is laid.
The present invention compared with prior art has the following advantages: generator is in light weight, is about traditional 1/2nd.Generator is few with enamelled wire, can save 1/3rd enamelled wire at least.Adopt the rare earth permanent-magnet steel to make multipole magnetic field, do not need excitation, saved magnet exciting coil, current collection copper ring, lead and excitation control loop, reliability increases greatly.Manufacturing procedure is less than the needed operation of conventional art.

Fig. 2 is a method for winding, and a, b, c represent the three-phase enamelled wire.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, described winding comprises stator 1, generator casing 2, generator windings 3 and permanent-magnet steel 4 etc.Stator 1 is arranged in shell 2, and described stator 1 is formed by some silicon steel sheet mutual superposition, the stack direction of silicon steel sheet and the parallel axes of described shell 2; The wire casing of some radial arrangement is set on stator 1, generator windings 3 is arranged in described wire casing; Described wire casing is distributed in the outer rim of stator 1 radially equably, and the outer end of wire casing is opened wide; The some blocks of permanent-magnet steels 4 that the inwall that is installed on described shell 2 is arranged at described stator 1 and 2 on described shell.In described permanent-magnet steel 4, the polarity of the adjacent both ends of adjacent two blocks of permanent-magnet steels 4 is opposite.In described motor windings 3, what be positioned at the wire casing bottom is a phase line, and what be positioned at the wire casing middle part is the b phase line, and what be positioned at the wire casing outer rim is the c phase line; Every group of phase line forms by 1 continuous enamelled wire.The quantity of the wire casing on the described stator 1 is 2: 1 or 3: 1 with the ratio of the quantity of described permanent-magnet steel 4.The width of described wire casing is slightly larger than the external diameter of single enamelled wire, and the enamelled wire of generator windings 3 is that single multilayer is laid in each wire casing.
Permanent-magnet steel 4 is wherein pressed N-S-N-S ... polarity arrange, the 1st, stator welded together changes after the silicon steel sheet punching press; The 3rd, generator windings is arranged in stator 1 outside uncovered wire casing, in the wire casing outwards is enamelled wire a, b, c one by one from the bottom.Contrast with existing conventional art: generator windings is in layer to lay with single enamelled wire, but not lay after the multiturn shaping, each winding all is that from the beginning a lead arrives end, the centre does not have fracture.This has broken through traditional handicraft fully, and rolling off the production line finishes, and being exposed at the outer enamelled wire of stator does not need shaping and cross-over connection, only need lead to casing and get final product outward.
During making, paste elongated bar permanent-magnet steel 4 on the inner chamber of generator casing 2, the length of permanent-magnet steel 4 is greater than generator unit stator 1 length, the wire casing of width and stator 1 is according to the generator principle design decision, higher voltage output during for acquisition low speed, generally be designed to tens permanent-magnet steels 4, the quantity of the wire casing on the corresponding stator 1 and the quantity of permanent-magnet steel 4 are directly proportional, and are generally 2: 1 or 3: 1.Because wire casing is many, the width of wire casing is very narrow comparatively speaking, has abandoned traditional following ray mode when rolling off the production line, and adopts under many group single lines.Corresponding certain wire casing, all be pairing that line from top to bottom, the induced voltage that has only self between adjacent like this two enamelled wires, can not produce and meet another group and cause abnormal conditions to take place, owing to be under the single line, whole generating machine copper consumption declines to a great extent, and generator output voltage is stable, is an outer rotor-stator structure of not seeing to meet in the past and new offline mode.
