So far the machine-carried type DC generator of using under the coal mine is still the requisite energy equipment of giving in transportation under the coal mine, communication, the monitoring, especially on Underground Locomotive Carrier, rail, trackless assistant conveyance diesel locomotive, generally use, but at present because the imitative moral product of most dependence on import of the airborne generating in down-hole or employing, this class generator volume is big, adopt the block rare earth permanent magnetic steel, the magnet steel consumption is big, power is little, cost an arm and a leg, weathering zone load power generation performance is poor, pressure adjusting structure complexity, rapid wear, maintenance and repair inconvenience can not be satisfied actual use needs.
China utility model patent CN2130302Y discloses a kind of " embedding the automobile-used rare permanent magnet generator of going up of adjustable type ", and the pawl utmost point of this generator is longer, and its rotating shaft is corresponding also long, and is extremely uneven and soon during rotating speed when pawl, rotating shaft heating and deliquescing, and generator easily blocks.
At present, the widely used separately excited dynamo of automobile and tractor has brush and slip ring, exists easy frictional dissipation problem.
The purpose of this utility model is to avoid the problems referred to above of prior art, and provide that a kind of weathering zone load generator performance is good, power is big, wide cut is adjusted output voltage, adopt existing automobile current generator voltage regulator to need not to join complicated peculiar part in addition, save rare earth magnetic steel consumption, brushless pressure regulation rareearth permanent-magnet DC generator that brushless does not have slip ring.
The purpose of this utility model reaches by following technical measures.
The utility model include housing, housing front end housing and rear end cap, be installed in bearing, magnetic guiding frame, pawl utmost point rotor, controlled excitation winding, magnetic shield and the commutation system and the voltage regulator at stator in the housing, rotating shaft, rotating shaft two ends.Pawl utmost point rotor is made of the left pawl utmost point and the right pawl utmost point and split rare earth magnetic steel assembly, split rare earth magnetic steel assembly is made of two annular slice magnet steel and two irony flux sleeves, the right pawl utmost point is anchored in the rotating shaft, and pressing the right pawl utmost point at the root of rotating shaft, to install annular slice magnet steel (13), flux sleeve (12), annular slice magnet steel (11) and flux sleeve (10) back and the left pawl that press successively extremely fixing.
Constitute the magnetic guiding frame of controlled exciting part and controlled excitation winding and be fixed in magnetic shield on the irony housing and be nested and embed fully in the pawl utmost point rotor.
Housing is by iron or aluminium or copper one-tenth, and when housing was irony, rotating shaft was the non-magnet material rotating shaft; When housing is an aluminium or when copper, rotating shaft is the permeability magnetic material rotating shaft.
Be enclosed within rotating shaft and press solidly the split rare earth magnetic steel assembly of extremely going up in right pawl forms pawl utmost point rotor magnetic flux maximum by magnetic guiding frame loop, improve generator low speed power generation performance, reduce the rare earth magnetic steel consumption, simultaneously, the pawl utmost point rotor that embeds the controlled exciting part in the whole pawl utmost point rotor also is the path that controlled excitation winding produces excitation, the controlled exciting part that embeds in the pawl utmost point rotor is regulated the interior size of current of controlled winding, and the magnetic flux that promptly changes pawl utmost point rotor reaches the purpose that wide cut is adjusted output voltage.
The utility model compared with prior art has following advantage:
1, the utility model permanent magnet excitation loop and controlled energized circuit are all by pawl utmost point rotor, and controlled exciting part embeds in the whole pawl utmost point rotor, regulate the size of current of winding in the controlled exciting part, but wide cut is adjusted output voltage.
2, the utility model adopts the split rare earth magnetic steel, divides the slabbing annular magnetic steel to split two places the bulk magnet steel in the prior art and is anchored in the rotating shaft, with the magnet steel consumption of minimum, reaches maximum power, bringing onto load starting good reproducibility, and overload capacity is strong.In the time of 600 rev/mins, can be with the 70W load, bigger by 30～40% than similar inlet generating acc power.
3, the utility model does not need brush and slip ring, and few easy workout part does not have special complex component, all can be used as the generator of existing automobile and tractor.
4, the surface of shell temperature rise is low, and generating output is stable, simple in structure, cheap, easy to maintenance, safe and reliable.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model.
Following the utility model will describe in detail embodiment (in conjunction with the accompanying drawings).
The utility model shown in Figure 1 include housing 2, housing 2 front end housing 15 and rear end cap 16, be installed in bearing 18 and 19, magnetic guiding frame 6, pawl utmost point rotor 17, controlled excitation winding 7, magnetic shield 9 and the commutation system 1 and the voltage regulator 8 at stator 5 in the housing 2, rotating shaft 3, rotating shaft 3 two ends.
Pawl utmost point rotor 17 is made of the left pawl utmost point 4, the right pawl utmost point 14 and split rare earth magnetic steel assembly (10,11,12 and 13), split rare earth magnetic steel assembly is annular slice magnet steel (11 and 13) and irony flux sleeve (10 and 12), the right pawl utmost point 14 is anchored in the rotating shaft 3, presses the right pawl utmost point 14 at the root of rotating shaft 3 and installs successively that to press annular slice magnet steel 13, flux sleeve 12, annular slice magnet steel 11 and flux sleeve 10 backs fixing with the left pawl utmost points 4.
