Description
Technical field
The utility model 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, be particularly suitable for using in the high environment of degree of protection requirement, belong 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 utility model is designed 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 beneficial effects of the utility model are that this absolutely empty cold anticyclone high-efficiency electric motor volume is little, lightweight, and 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 utility model;
Wherein: 1 rotor, 2 bearings, 3 aerofoil fans, 4 end caps, 5 stators, 6 hollow coolers, 7 air exhausters, 8 fan shrouds.Accompanying drawing 2 is cooler construction schematic diagrames of the absolutely empty cold anticyclone high-efficiency electric motor of the utility model.
Embodiment
As shown in Figure 1, a kind of specific embodiment of the absolutely empty cold anticyclone high-efficiency electric motor of the utility model, comprises rotor (1), bearing (2), aerofoil fan (3), end cap (4), stator (5), hollow cooler (6), air exhauster (7), fan shroud (8).Wherein, housing and the outlet housing of hollow cooler are formed by Plate Welding, in enclosure interior, longitudinally with dividing plate, merotomize and are convenient to form wind path, are also convenient to fixedly cooling water pipe; The material of cooling water pipe is that fine copper or the copper alloy that conductive coefficient is high is conducive to motor radiating, the radiating tube of contrast aluminium radiating tube and steel, the quantity of radiating tube greatly reduces, and the inside and outside windage of radiating tube also reduces greatly, and the power of motor internal fan and outside blower fan also reduces greatly; Low pressure independence axial-flow exhaust fan is from cooler inner outwards exhausting rather than air blast inwards, and the centrifugal fan that contrast motor shaft head carries has advantages of that loss is low.
Motor internal, at upper two aerofoil fans (3) of installing of rotor (1), contrasts centrifugal fan and has advantages of that equally loss is low in the situation that air quantity is identical.
Stator (5) adopts the magnetic slot-seal with magnetic conduction effect to improve efficiency and the power factor of motor.
The iron core of rotor (1) and stator (5) adopts low-loss 50W400 silicon steel sheet, has reduced the core loss of motor.
Radial clearance between motor internal aerofoil fan (3) and fan shroud (8) reduces to prevent blast leakage as far as possible.
Fan shroud (8) adopts glass-reinforced plastic material, dwindle and stator coil between distance, increase the draught area of fan shroud (8) outside.
Claims (6)
