Abstract
The invention discloses the generator with high quality and low energy consumption by using rare earth permanent magnet and electricity mixed excitation. The ivnention possesses the advantages, such as small size, lightweight, compact structure, high reliability, small distortion factor of the load waveform, high loading capacity, low cost, especially voltage adjustment with high accurate etc. The new techniques of insulating magnetism by air and one-off magnetizing the whole rotor are adopted in the invention. The outer fringe of the stator is designed as the 'W' typed air channel so as to strnegthen the heat dispersion effect and raise the working efficiency. The invention is especially suitable for gasoline engine and disel engine to buildup the generator set with high quality and low energy consumption.
Description
The invention discloses a kind of main excitation part that adopts the novel rare-earth magnet steel that generator is provided, the electromagnetic field that coil produces provides the secondary excitation part of generator, integrates the advantage of rare earth permanent magnet and traditional electrical excitation generator, forms mixed reed-type novel electricity generator.The stator outer rim is designed to " W " type air channel is used for closed mute generator group and can strengthens radiating effect, increase work efficiency, be particularly suitable for and gasoline engine, engines such as diesel engine are formed the high-quality low-energy-consumption generator group.
The invention is characterized in and utilize novel rare-earth magnetic material magnetic energy product height, power density is big, and operational reliability reaches plurality of advantages such as efficient height well.Utilize electric excitation can change the characteristics that the excitation field size is come constant generator voltage, make its mutual supplement with each other's advantages, the voltage that can improve generator adjust precision can bring into play again its take advantage of carry perception or the line load ability strong, the load irregularity of wave form is little, plurality of advantages such as rare earth material is low-consuming, and the complete machine low cost of manufacture and the market competitiveness are strong.
The present invention has adopted multinomial innovative technology on the mechanism of power generation technology for making, specific implementation method is as follows:
Adopt air on rotor punching, to offer the air magnet isolation tank and offer the interior slotted eye of placement rare earth magnetic steel and the exterior notch of coiling every magnetic new technology and die stamping method, punching after being shaped laminated be one, rectangle that will not magnetize or novel rare-earth magnet steel such as trapezoidal embed in the rotor that laminates after the shaping in the slotted eye again, coiling in the rotor exterior notch then, again integral body has been changeed and insulated and preservative treatment, with the disposable new technology that magnetizes of the whole employing of rotor, can increase substantially the consistency precision of production work efficiency and product lot quantityization so at last.
Adopt air can reduce leakage flux every the magnetic new technology, whole rotor can be fabricated to the incorporate structure of tightly playing.Its volume is little, in light weight, mechanical strength is good and composite excitation efficient is high and be convenient to the production of mass.
Adopt rectangle or novel rare-earth magnet steel such as trapezoidal can reduce material usage and machining period expense, the unit integrated cost is about half of watt shape or other special-shaped rare earth magnetic steel.Unit mass average power ratio watt shape or other special-shaped rare earth magnetic steel can improve about 20%～30%, and especially the consistency of magnetic flux density is that watt shape or other special-shaped rare earth magnetic steel are incomparable.
Inherent defects such as the electromagnetic field that adopts coil sections to change comes constant generator voltage not only can improve the pressure regulation precision of complete machine but also can avoid traditional electrical excitation generator excitation complex structure, and many and operational reliability difference of electronic devices and components and efficient are low.
Adopt rectangle or the trapezoidal novel rare-earth magnet steel that waits to provide the generator main magnetic flux can improve overall efficiency and operational reliability, avoided watt shape or other special-shaped rare earth magnetic steel when running up, to be subjected to accidents such as the restriction of intensity is possible chipping.
Adopt the disposable new technology that magnetizes of integral rotor can improve magnetic flux density and improve the consistency of rotor field, multiplicable raising production work efficiency in mass production especially, the inconvenience that power is brought to assembly work is told in the strong suction that the rare earth magnetic steel after avoiding magnetizing produces.
The present invention is further illustrated below in conjunction with accompanying drawing: Fig. 1 is a structural representation of the present invention; Fig. 2, Fig. 3 are a pair of utmost point rotor combining structure schematic diagram of the present invention; Fig. 4, Fig. 5 are two pairs of utmost point rotor combining structure schematic diagrames of the present invention; Fig. 6, Fig. 7 are the combining structure schematic diagram of a pair of polar moment shape of the present invention or novel rare-earth magnet steel such as trapezoidal and rotor; Fig. 8, Fig. 9 are a pair of utmost point rotor structure schematic diagram of the present invention; Figure 10, Figure 11 are the combining structure schematic diagram of two pairs of polar moment shapes of the present invention or novel rare-earth magnet steel such as trapezoidal and rotor; Figure 12, Figure 13 are two pairs of utmost point rotor structure schematic diagrames of the present invention; Figure 14, Figure 15 are stator laminating structure schematic diagram of the present invention; Among the figure: 1 is the stator assembly; 2 is the external groove type rotor punching; 3 is the internal groove rotor punching; 4 is rectangle or novel rare-earth magnet steel such as trapezoidal; 5 is rotor coil; 6 are rotating shaft; 7 is bearing; 8 is fan blade; 9 is outer end cap; 10 is inner end cap.
