Abstract
The invention provides an air-air cooled high-voltage high-efficiency motor which is at voltage levels of 6000V and 10000V, has a protection grade above IP44, has a good cooling effect, and is small in size and power-saving. The motor is characterized in that a cooling pipe of a cooler adopts a thin-wall (0.5-1.5mm thick) copper pipe or an alloy copper pipe with high thermal conductivity coefficient to improve the heat exchange amount and reduce the required air volume, one end of the cooler is equipped with a 380V low-voltage independent exhaust fan, a stator adopts a magnetic slot wedge, the efficiency and the power factor of the motor are improved, and stator and rotor cores adopt low-loss 50W400 silicon steel sheets; and a fan in the motor is a low-loss axial flow fan, and the internal wind path adopts radial ventilation to reduce the internal resistance. The air-air cooled high-voltage high-efficiency motor of the invention has the advantages of small size, light weight, high efficiency and low energy consumption.
Description
Technical field
The present invention relates to a kind of high-tension motor, especially a kind of degree of protection is high, good cooling results, volume is little and save the absolutely empty cold anticyclone high-efficiency electric motor of electric power, is particularly suitable for using in the high environment of degree of protection requirement, belongs to mechanical designing technique field.
Background technology
The main electric pressure of existing absolutely empty cold anticyclone motor is 6000V and 10000V, and the product for degree of protection more than IP44 mostly exists the inside and outside fan of motor and wind path design unreasonable, and fan loss is high; Core loss is high, and the cooling water pipe selection of cooler is unreasonable, and volume is large, and required cooling air quantity is large, and quality is heavier, and the namely heat exchange amount of cooling effect of cooler is not very high, the shortcoming that the whole efficiency of motor is not high.
Summary of the invention
It is 6000V and 10000V that the present invention designs a kind of electric pressure, degree of protection more than IP44, good cooling results, volume is little and save the absolutely empty cold anticyclone high-efficiency electric motor of electric power, the feature of this motor is cooler with the high thin-wall copper pipe of conductive coefficient or alloy copper pipe as cooling water pipe, the low-voltage independence blower fan of 380V is equipped with in one end of cooler, stator adopts magnetic slot-seal to improve efficiency and the power factor of motor, and stator and rotor iron core adopts low-loss 50W400 silicon steel sheet.Internal fan for electric machine adopts low-loss tube-axial fan, and inner wind path adopts radial ventilation, reduces inner windage.
The invention has the beneficial effects as follows that this absolutely empty cold anticyclone high-efficiency electric motor volume is little, lightweight, efficiency is high, energy consumption is low.
accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the absolutely empty cold anticyclone high-efficiency electric motor of the present invention;
Accompanying drawing 2 is cooler construction schematic diagrames of the absolutely empty cold anticyclone high-efficiency electric motor of the present invention;
Wherein: 1 rotor, 2 bearings, 3 aerofoil fans, 4 end caps, 5 stators, 6 hollow coolers, 7 air exhausters, 8 fan shrouds.
