Description
Technical field
The present invention relates to a kind of generator.Specifically, be a kind of small-sized single-wire multipole external rotor single-phase generator.
Background technology
Know all that at the generator production industry existing small generator mostly is the internal rotor generator.The internal rotor of this internal rotor generator is dragged by power, and excitation produces magnetic field in the rotating shaft, perhaps adorns permanent-magnet steel in the rotating shaft, and the generating winding is embedded on the outer casing inner wall.Generating winding wherein is made up of multiturn coil.Because the generating winding of this internal rotor generator is made up of multiturn coil, not only the enamelled wire of Xu Yaoing is many, the consumption copper material is many, manufacturing cost is high, and generator weight is heavier, is example with the generator of 10KW specification, and its weight is up to 300Kg.
Summary of the invention
The problem that the present invention will solve provides a kind of single-wire multipole external rotor single-phase generator.This generator, the enamelled wire that its stator winding uses is few, it is few to consume copper material, low cost of manufacture not only, and can alleviate the weight of generator greatly.
For solving such scheme, the present invention takes following technical scheme:
Single-wire multipole external rotor single-phase generator of the present invention comprises shell, and stator is arranged in the shell.Some blocks of permanent-magnet steels are arranged on the inwall of said shell, and the polarity of adjacent two same ends of permanent-magnet steel is opposite.Said stator is formed by some silicon steel sheet mutual superposition, the stack direction of silicon steel sheet and the parallel axes of said shell.The wire casing that some radial arrangement are arranged on the stator has the generating winding in the wire casing.Be characterized in that said wire casing is uniformly distributed in the outer rim of stator radially, the wire casing outer end is communicated with the stator outer edge.The quantity of said wire casing is 6 integral multiple.Said generating winding contains a enamelled wire, b enamelled wire and c enamelled wire; A enamelled wire, b enamelled wire and c enamelled wire are positioned over 1,2,3 three wire casing bottom respectively; And according to 1-6-1-6; 2-5-2-5; The wire casing order continuous winding of 3-4-3-4; After intact, a enamelled wire, b enamelled wire and c enamelled wire bridging become a lead, as the output of single-phase generator.
Wherein, the quantity of the wire casing on the said stator is 3:1 or 2:1 with the ratio of the quantity of said permanent-magnet steel.The width of said wire casing is slightly larger than the external diameter of single enamelled wire, and the enamelled wire of generating winding is that single multilayer is laid in each wire casing.
Adopt above scheme, the present invention has and has the following advantages:
Can find out that by above scheme because said wire casing is uniformly distributed in the outer rim of stator radially, the wire casing outer end is communicated with the stator outer edge.The quantity of said wire casing is 6 integral multiple.Said generating winding contains a enamelled wire, b enamelled wire and c enamelled wire; A enamelled wire, b enamelled wire and c enamelled wire are positioned over 1,2,3 three wire casing bottom respectively; And according to 1-6-1-6; 2-5-2-5; The wire casing order continuous winding of 3-4-3-4; After intact, a enamelled wire, b enamelled wire and c enamelled wire bridging become a lead, as the output of generator.Make that coil is single, significantly reduced the consumption of enamelled wire, compared by the generating winding that multiturn coil constitutes with tradition, the enamelled wire consumption has only 2/3rds of conventional electric generators, has saved 1/3rd enamelled wire.Because the enamelled wire that uses is few, it is few to consume copper material, has not only reduced the manufacturing cost of engine, has also alleviated the weight of generator greatly.Engine with the 10Kw specification is an example, and engine weight of the present invention has only 98Kg, 1/3rd of not enough conventional engines.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
As shown in Figure 1, single-wire multipole external rotor single-phase generator of the present invention comprises shell 2, is provided with stator 1 in the shell 2.Some blocks of permanent-magnet steels 4 are installed on the inwall of said shell 2, and the quantity of permanent-magnet steel 4 is looked the specification of generator and is decided.Permanent-magnet steel 4 is wherein pressed the polarity of N-S-N-S and is arranged, and makes that the polarity of adjacent two permanent-magnet steel 4 same ends is opposite.Said stator 1 is welded the stack direction of silicon steel sheet and the parallel axes of said shell 2 after by some silicon steel sheet mutual superposition.Be processed with the wire casing of some radial arrangement on the stator 1, be wound with generating winding 3 in the wire casing.
Said wire casing is distributed in the outer rim of stator 1 radially equably, and the outer end of wire casing is communicated with stator 1 outer edge.Said generating winding 3 contains a enamelled wire, b enamelled wire, c enamelled wire; These three enamelled wires are positioned over 1,2,3 three wire casing bottom respectively; And according to 1-6-1-6; 2-5-2-5; The wire casing order of 3-4-3-4, continuous winding is after the completion; A enamelled wire, b enamelled wire, c enamelled wire bridging are become a lead, as the output of single-phase generator.The quantity of the wire casing on the said stator 1 is 6 integral multiple, with the ratio of the quantity of said permanent-magnet steel 4 be 3:1.The ratio of said wire casing quantity and the quantity of said permanent-magnet steel 4 depends on the needs for being 2:1 also.The width of said wire casing is slightly larger than the external diameter of single enamelled wire, and the enamelled wire of generating winding 3 is that single multilayer is laid in each wire casing.Wherein, 1-6-1-6; 2-5-2-5, the wire casing of 3-4-3-4 is meant in proper order: a enamelled wire is the 1st wire casing from every group of wire casing and the 6th wire casing is walked around, b enamelled wire the 2nd wire casing from every group of wire casing and the 5th wire casing is walked around, the c enamelled wire only walk around by the 3rd wire casing from every group of wire casing and the 4th wire casing only only.
The present invention and the contrast of existing conventional art: generating winding 3 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.Broken through traditional handicraft fully, rolling off the production line finishes, and is exposed at the outer enamelled wire of stator 1 through twice cross-over connection, is linked to be a lead and leads to outside the shell 2 and get final product.
Said permanent-magnet steel 4 is a strip, and they stick on the inwall of shell 2.The length of permanent-magnet steel 4 is greater than 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 is 6 integral multiple; Be directly proportional with the quantity of permanent-magnet steel 4, be 3:1 or 2:1.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.
