Abstract
The utility model discloses a collector ring device of an inner feedback motor, which comprises a collector ring seat fixed on a motor seat, a casing arranged on the collector ring seat, and a collector ring and an electric brush arranged on a motor shaft inside the casing. A first fan is disposed on the motor shaft inside the casing closely to an air inlet, small vanes are arranged on the side face of the collector ring, and a second fan is arranged at an air outlet at the bottom of the collector ring seat. The collector ring device excellently resolves the problems of cooling of the collector ring and the electric brush and emission of carbon powder during speed adjustment of the inner feedback motor by adopting the triple cooling means, and has service life of the electric brush and the collector ring one time higher than that of an ordinary collector ring device.
Description
Technical field:
The utility model belongs to Internal-Feedback Adjustable-Speed Motor, is specifically related to a kind of collector machine of interior feed machine.
Background technology:
Blower fan, water pump are the power consumption equipments that has a large capacity and a wide range in the national economy, and its power consumption accounts for more than 40% of total amount of generating.At present, most of blower fans, water pump all adopt valve or deep bead to regulate flow to satisfy the requirement of load variations, and waste of energy is serious, therefore are badly in need of the variable speed energy saving product.In the variable speed energy saving product, particularly in low-voltage small-capacity motor system, RHVC has obtained using comparatively widely and admitting, and in the high-voltage large-capacity governing system, because of the cost of variable-frequency governor very high, volume is bigger, has problems in the application, also is difficult at present apply on a large scale.And the inner feedback speed-regulating technology is complied with this trend exactly, on traditional tandem control theoretical foundation and the advanced technology of development development, economic and practical high-tech product.That the inner feedback speed-regulating device has is simple in structure, safeguard easily, can realize advantage such as continuously smooth ground speed governing, and when especially a capacity square torque load(ing) was controlled greatly to blower fan, pump class etc., its energy-saving effect was very considerable.The variable speed energy saving operation and the effect that are particularly suitable for big-and-middle-sized water pump are remarkable, generally can reclaim the armamentarium investment by energy-saving efficiency less than 2 years, so they have application value widely.
Owing to during machine operation, be subjected to the harmonic effects of internal feedback control cubicle, cause the rotor kelvin effect, rotor voltage raises during low speed simultaneously, and collector machine can produce a large amount of heats.The heat radiation of existing collector machine is to be undertaken by the centrifugal fan that is located at the collector ring front end, because this fan is subjected to the restriction of installation site, size is less, and air supply mode is exhausting, and blast is less, can not effectively get rid of heat when making the collector ring speed governing in the device, can not get rid of the carbon dust that produces in the collector ring course of work, cause the collector ring heating serious, make Internal-Feedback Adjustable-Speed Motor have the hidden danger of burning, this also is the bottleneck that the rapid large tracts of land of this serial motors of restriction is promoted.Also there are not technical measures at present at this problem.
The utility model content:
For addressing the above problem, the purpose of this utility model provides a kind of collector machine of interior feed machine, and it can not only solve the cooling problem of collector ring and brush, the carbon dust in the collector machine can also be discharged.
The technical scheme that realizes above-mentioned purpose is:
The collector machine of interior feed machine, comprise the current collection ring seat that is fixed on the electric machine stand, be located at housing on the current collection ring seat, be located at the collector ring and the brush that are positioned on the housing motor shaft, in housing, be provided with first fan near the air inlet place on the motor shaft, be provided with little fan blade in the collector ring side, the air outlet place is provided with second fan in current collection ring seat bottom.
Described first fan adopts the major diameter centrifugal fan.
Described second fan adopts independent current source grid type fan, is located in the volute case.
The place is provided with ventilating duct at described housing air inlet.
During the work of the utility model device, under the effect of first fan, cold air is introduced along ventilating duct from the air inlet of current collection ring seat upper shell, enter the junction of collector ring and brush, cool off its surface, under the effect of little fan blade, clear away the carbon dust that is attached to the collector ring surface simultaneously, by second fan air of first fan and the discharge of little fan blade is derived outside the current collection ring seat, and take carbon dust out of.
The utility model is by being provided with large-sized first fan in the collector ring rear end, adopt the blowing mode, can improve blast, the rough air that produces when rotating by the little fan blade that is located on the collector ring prevents that carbon dust is at the collector ring surface deposition, utilization is located at second fan of the employing independent current source of current collection ring seat bottom, its rotating speed is not subjected to the influence of motor speed, can guarantee stable air draft, row's carbon effect.Because the cooling and the carbon dust of collector ring, brush are discharged problem when adopting above-mentioned triple types of cooling to solve interior feed machine speed governing well, and brush, collector ring life-span are doubled than common collector machine.Instructions for use in satisfying during the speed governing of feed machine has application value widely.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
