Abstract
The invention discloses a ten-pole electric generator with a salient pole integral rotor. The ten-pole electric is configured as follows: a rotor punching is a salient pole integral punching; the excircle is in an eccentric design and each magnetic pole rotor is provided with grooves for damping bars and holes for rotor bolts; each magnetic pole has six damping bars; a damping plate is arranged at each of the two ends of a rotor iron core separately; a rotor screw shaft is axially mounted between a rotor pole body and a magnet yoke; and an inter-pole bracket and a straight welding seam are mounted between two magnetic poles. The ten-pole electric generator has the advantages that the ten-pole electric generator is good in performance; the voltage waveform deviation factor of a no-load wire is 0.77%; the adjustment rate of full-load transient voltage loaded suddenly is -10% and the recovery time is 0.7 second; the adjustment rate of the full-load transient voltage downloaded suddenly is +15% and the recovery time is 0.8 second; the data is far beyond the performance requirements of the national standard; and the ten-pole electric generator is high in reliability, and the rotor windings are still not deformed after a long-term running of the generator.
Description
Technical field
The present invention relates to a kind of generator, especially a kind of ten pole generators of salient pole integrate rotor.
Background technology
In, low-speed diesel engine is little owing to wearing and tearing, failure rate is low, maintenance cycle is long, and the life-span is long, good operation stability, reliability is high, incendivity heavy oil, therefore good economy performance is the main type of Technique For Push Diesel Engine always, and in matching with it, low speed diesel engine generator is widely used.The Fast Construction of boats and ships, is beneficial to the development of marine diesel engine genset industry, and ten pole generators are more and more subject to the favorable comment of vast manufacturing enterprise and user.Ten pole generator numbers of poles are many, and rotor diameter is large, and weight is large, so require that rotor has good intensity, tradition ten pole generator adopts Split-type rotor structure, and this structure fabrication process is complicated, cost is high, and rotor strength is poor, damping stability is poor, also can produce secondary air gap, affects the performance of motor; And usually can add rotor press plate in order to the structural strength ensureing rotor core, the rotor press plate at rotor core two ends makes rotor winding end long and causes distortion, affects the reliability of generator.
Summary of the invention
The object of the present invention is to provide a kind of ten pole generators of salient pole integrate rotor, this ten pole generator is three-phase brushless synchronous generator, rotor overall convex electrode structure, performance is good, reliability is high advantage that it has.
The present invention is achieved like this: a kind of ten pole generators of salient pole integrate rotor, and it comprises rotor core, rotor windings; Rotor windings is wound in rotor core, it is characterized in that: described rotor core comprises rotor punching, amortisseur bar, damping sheet, multi-rotor screw, interpolar support and straight bead, rotor punching is the overall punching of salient pole, cylindrical adopts eccentric design, and every pole wheel punching all has the groove of amortisseur bar and the hole of rotor bolt; Amortisseur bar is every magnetic pole 6, damping sheet respectively has one piece at rotor core two ends, multi-rotor screw is axially arranged between rotor pole body and yoke, interpolar support and straight bead are installed between two magnetic poles, and the acting in conjunction of amortisseur bar, damping sheet, multi-rotor screw and straight bead ensure that the structural strength of rotor core.
Described rotor core two ends do not adopt rotor press plate, and rotor winding end is short.
The invention has the advantages that: performance is good, non-loaded line voltage-form distortion rate is 0.77%, and it is-10% that impact is fully loaded with transient voltage regulation factor, recovery time is 0.7s, dashing forward and unloading fully loaded transient voltage regulation factor is+15%, and recovery time is 0.8s, and above data are considerably beyond the performance requirement of national standard; Reliability is high, and after generator works long hours, rotor windings is not still out of shape.

Embodiment
The present invention implements like this: a kind of ten pole generators of salient pole integrate rotor, and it comprises rotor core (1 to 6), rotor windings 7; Rotor windings 7 is wound in rotor core (1 to 6), it is characterized in that: described rotor core (1 to 6) comprises rotor punching 1, amortisseur bar 2, damping sheet 3, multi-rotor screw 4, interpolar support 5 and straight bead 6, rotor punching 1 is the overall punching of salient pole, avoid the secondary air gap of Split-type rotor, the non-uniform gap that the cylindrical of eccentric design produces makes generator waveform good; Amortisseur bar 2 is every magnetic pole 6, ensure that the dynamic property that generator is good; Interpolar support 5 is arranged between two magnetic poles, and the ventilating opening that rotor is formed by interpolar support 5 dispels the heat.
Damping sheet 3 respectively has one piece at rotor core two ends, and multi-rotor screw 4 is axially arranged between rotor pole body and yoke, and straight bead 6 is between two magnetic poles.The acting in conjunction of amortisseur bar 2, damping sheet 3, multi-rotor screw 4 and straight bead 6 four ensure that the structural strength of rotor core, eliminate the rotor press plate at rotor core two ends, not only reduce material, the more important thing is that to make rotor windings 7 end short, the centrifugal force of such rotor windings 7 end generation is when rotated just little, is not easy to be out of shape the reliability that also just ensure that rotor.
