Abstract
The invention relates to the generator technology field, in particular to a generator stator plate structure. A plurality of winding slots are equipped on the internal circumference of the stator, and the direction of the winding slot is deviated from that of the stator axis line and forms a certain included angle with it. By the setting of the skewed slot, the invention is capable of perfecting the output wave shaper of the generator and enhancing the efficiency, thus being widely applied in the excitation generator.
Description
Technical field:
The present invention relates to technical field of generators, refer in particular to and a kind ofly use special material and in conjunction with the generator of specific stator laminating structure.
Background technology:
Existing traditional electrical excitation generator was invented over more than 100 year, though technology is very ripe, was subjected to the restriction of material and structure; Exist that volume and weight are big, structure and manufacturing process complexity, copper loss iron loss are big, waveform difference, efficient is low, energy consumption is big, 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 the rareearth magnetic material neodymium iron boron (NdFeB) with its magnetic energy product height, HCJ is big and Curie temperature is high, is difficult for remarkable advantages such as degaussing; In the electronic product development, will progressively replace the big heavy again electric excitation generator of existing energy consumption.Last century end, 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 generator of mechanical energy transformation efficiency.
Technical problem of the present invention is achieved by the following technical solution: the inner periphery of stator is provided with some winding slots, the angle that winding slot deviation in driction axis stator is certain.
Angle between winding slot direction and the axis stator is the 5-15 degree.
Angle between winding slot direction and the axis stator is 10 degree.
Rotor of the present invention adopts the NdFeB rare earth permanent-magnetic material, adopts hermetically sealed hypoxemia technology, and oxygen content can be strict controlled in 1200ppm once, about total amount of rare earth to 30%, is enough to obtain higher magnetic property.Stator adopts flume structure, and evenly cutting magnetic line has been eliminated influencing each other between the stator slot each harmonic effectively, has effectively suppressed the wave distortion of output voltage, and the waveform of output is perfect sine wave substantially.After having adopted new design, epitrochanterian magnetic energy product can be brought up to 50MGOe; And shortened stator core length, and 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, and irregularity of wave form＜2.2% substantially exceeds national military products standard (＜6%) and adopted the digital electricity generating of complex digital technology suitable; And cost, energy consumption are significantly less than digital electricity generating, and structure is much also simple, moves more reliable.With six KW generator groups is 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.
Description of drawings:
The present invention is further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is that the master of stator 1 of the present invention looks schematic diagram;
Accompanying drawing 2 is that the side of stator 1 of the present invention is cutd open schematic diagram.
Embodiment:
See accompanying drawing 1,2, the inner periphery of stator 1 of the present invention is provided with some winding slots 11; The certain angle of winding slot 11 deviation in driction stators, 1 axis, this angle is the 5-15 degree; Be specifically as follows 8,10,12 degree etc.Best angle is 10 degree.After rotation 10 degree or the some angles winding slot 11 is connected as a single entity between stator 1 punching; Weld and get final product.By the design of aforementioned angle, can improve the output waveform of generator, raise the efficiency.
More than be description, but be not limiting the scope of the invention preferred embodiment of the present invention; The equivalence techniques scheme all according to above stated specification, that those skilled in the art can get all belongs to protection scope of the present invention.
