Description
Technical field
The present invention relates to technical field of generators, a kind of especially generator torsion chute stator.
Background technology
Existing traditional electrical excitation generator was invented over more than 100 year, although technology is very ripe, was subjected to the restriction of material and structure; Exist that volume and weight are large, structure is complicated with manufacturing process, the copper loss iron loss is large, waveform difference, efficient is low, energy consumption is large, carry many inherent defects such as inductive load ability.Adopt new material, new technology, new process development more energy-conservation, more high-quality novel electricity generator has become an urgent demand in epoch.A new generation's rareearth magnetic material admire iron boron (NdFeB) high with its magnetic energy product, in to examine coercive force large and Curie temperature is high, be difficult for the remarkable advantages such as degaussing; In the electronic product development, will progressively replace the large again electric excitation generator of heaviness of existing energy consumption.Last century Mo, the rare earth permanent-magnetic generator that the permanent-magnetic field that utilizes rare earth magnetic steel to produce generates electricity comes out, owing to it is simple in structure, reliable, the high welcome that obtains market of efficient.Though existing rare-earth generator has many advantages, but still have many weak points, mainly contain: 1. waveform is good not enough, and the aberration rate of waveform generally can be greater than 6%.2. efficient is high not enough, and the efficient that its mechanical energy is converted into electric energy can only reach about 80%.
Summary of the invention
The technical problem that the present invention solves is to provide a kind of output waveform that can improve generator, improves the torsion chute stator of the generator of mechanical energy transformation efficiency.
Technical problem of the present invention is achieved by the following technical solution:
Be provided with winding slot on the inner periphery of the torsion chute stator of described generator, the angle of winding slot and axis stator is the 3-20 degree;
Be connected to one between the winding slot;
Describedly be fixedly connected as welding.
Described angle is 3,5,8,11,12,13,15,18 or 20 degree.
In production and processing generator process, when the assembling generator unit stator, the stator piece of generator stack is assembled to the expection specification, during assembling stator piece is reversed certain angle, after making the winding slot that arranges on the inner periphery of stator depart from the certain angle 3 of axis stator 4, winding slot 2 is connected, welds and to obtain the torsion chute stator.
See accompanying drawing 1,2, be provided with some winding slots 2 on the inner periphery of torsion chute stator of the present invention; Winding slot 2 departs from the certain angle of axis stator 4, and this angle is 3 one 20 degree; Be specifically as follows 3,5,8,11,12,13,15,18,20 degree etc.Preferred angle is 11 degree.After rotation 11 degree or the some angles winding slot 2 is connected as a single entity between the stator piece; Weld and get final product.By the design of aforementioned angle, can improve the output waveform of generator, raise the efficiency.
Beneficial effect
Stator adopts flume structure, and evenly cutting magnetic line has been eliminated influencing each other between the stator slot each harmonic effectively, establishment the wave distortion of output voltage, the waveform of output is perfect sine wave substantially.After having adopted new design, epitrochanterian magnetic energy product can be brought up to 50MG0e; And shortened stator core length, reduced the use amount of enamelled wire, keeping on the reliable basis simple in structure, increased substantially the electric property of generator, many indexs all are better than national standard: temperature rise is less than half of national standard, irregularity of wave form＜2.2% substantially exceeds national military products standard (＜6%), and has adopted the digital electricity generating of complex digital technology suitable; And cost, energy consumption are significantly less than digital electricity generating, and structure is also simply too much, moves more reliable.Take six KW generator groups as example, used power is 15 horsepowers single-cylinder air-cooled gasoline engine, the conventional electric generators maximum can only be dealt into 6.5 kilowatts, and changed generator of the present invention, maximum can be dealt into more than 8 kilowatts, improve generating capacity 23%, and volume, weight, oil consumption are all constant, band inductive load (mainly being the power consumption equipment that motor etc. has coil), ability is doubled many especially, and waveform improves greatly, and the efficient that mechanical energy is converted into electric energy has reached more than 85%, thereby huge economic benefit and social benefit are arranged.
