According to the efficient mixed excitation generator, resisting moment is small, weight is low, power density is large, efficiency is high, energy is obviously saved, failures are less, service life is long, operation manufacturing cost and maintenance cost are low, and the efficient mixed excitation generator can replace an existing power generation assembly which is large in energy consumption.
Description
Technical field
The efficiently mixed excitation generator of the present invention belongs to the environmental protection and energy saving machine field.
Background technology
Existing generator adopts mechanical energy to be converted to electric energy and generates electricity, the exciting power of generator adopts electric excitation winding to provide, the generator body of electricity excitation structure is great, the inherent shortcomings such as power density is little, efficiency is low, energy consumption is large, fault is many, manufacturing cost and operation expense height.
Summary of the invention
The present invention relates to a kind of efficient mixed excitation generator, exciter adopts permanent magnet and electric excitation composite excitation structure, can obviously reduce manufacturing cost, and voltage regulation is good, voltage-form distortion rate is little, can significantly improve the complete machine dynamic property.The moment of resistance is little, body weight is light and handy, power density is large, efficiency is high, energy-conservation obviously, few, the long service life of fault, manufacturing cost and operation expense low, the large generating equipment of alternative existing energy consumption.
Compared with prior art, its advantage is technical solution of the present invention:
1, excitation stator [3] adopts permanent magnet and electric excitation composite excitation structure, can obviously reduce manufacturing cost.Voltage regulation is good, voltage-form distortion rate is little, can significantly improve the complete machine dynamic property.
2, permanent magnetic material is done orthogonal permanent magnet [5] shape, and the magnet steel cost of comparable existing employing tile shape permanent magnet shape is low and power density is high.
3, have rectangular aperture groove [6] on n magnetic pole of excitation stator [3], rectangle permanent magnet [5] embeds and cements in formation n in the rectangular aperture groove [6] on excitation stator [3] magnetic pole N-S utmost point exciter is not waited
The air gap field structure.Be embedded with winding [7] on excitation stator [3] magnetic pole, form the composite excitation structure, this structure can improve air gap flux density and the power density of complete machine greatly, can make up the low little technological deficiency of power density that reaches of existing product air gap flux density.
4, excitation stator [3] winding [7] and excitation rotor [4] winding [8] are made concentrated winding, and this winding can obviously reduce coiling man-hour and wire consumption, significantly improves winding efficiency, is convenient to low cost, large-scale standardized production.
5, excitation stator [3] is arranged in end cap [9] inner circle, and excitation rotor [4] and main rotor [2] are arranged on the upper high integral structure of concentricity that forms of same rotating shaft [10].
