8、protection of motor main body enclosure is IP44,IP54and IP55.And for the flameproof structure, see Figure1.3.3 The cooling form of the motor: IC411 total enclose self-fan cooling for frame size 80-355 motor.3.4 The motor fans are made form reinforced acrylic plastering,HT150 gray cast iron or weldin

9、g of steel plate. For plastic fan, the resistance measured according to the method specified in 60079-0：2004shall not greater than 1G.3.5 The stator windings use polyester enamel round copper wire (Class F) or polyimide enamel round copper wire (Class H).The complete wound stator cores are vacuum-pr

10、essure-impregnated(VPI) to make them be a solid integral. This process enables the windings to possess excellent electrical and mechanical properties, high moisture-resistant ability and thermal stability.3.6The motors rotor adopts squirrel cage type. The aluminum motor rotor is fixed on the shaft b

11、y means of shrink fit and balanced well to make motors operate smoothly with little nose and vibration.3.7 The motors are provided with a cylindrical shaft extension and transmit by means of coupling or spur-gear unit. For spur gearing, the gear pitch diameter should not less than 3 times of shaft e

12、xtension diameter. Two shaft extension or special shaft-extension motors can also be produced by ordering request.3.8The terminal box is located in the top of the motor. The terminal boxes are designed and fabricated with either three or six terminals with one or two entries. Another galvanized stee

13、l or copper screw in the box is fixed for inside earthing. The entries of the terminal box are suitable for rubber-insulated cable, conduit entry and explosion-proof flexible pipe (armouring cable). The protection degree of terminal boxes id IP55.For the construction of terminal box, see Figures23.4

14、 Explosion Protection Features4.1 These series motors are so designed in mechanical construction that should the explosive mixture inside the motors be ignited by some cause or other ,the flame poof enclosures are capable of withstanding the explosion, and of preventing the sparks inside passing thr

15、ough the flameproof join surfaces and the ignition of explosive mixture surrounding the enclosures by sparks.4.1.1 The parts constituting flameproof enclosure shall be tested hydrostatically according to the specification in EN60079-1：2004 to ensure them to withstand the maximum explosion pressure.4

16、.1.2 Exercise strict control over the flameproof joint surfaces length, gap or diameter clearance, the surface roughness between the surfaces of all the pats constituting the flameproof enclosure and the electric clearance and creepage distance between the bare conducting parts and the metallic encl

17、osure the cable from harm.4.2 In order to ensure flameproof property of the enclosure, the bolts jointing the flameproof enclosure should be provided with spring washers to prevent working loose. After fastening bolts in bolt blind hole, the thread allowance should be remained between the screw or b

18、olt tail and the thread-hole bottom. The thickness of metal surrounding bolt blind holes on enclosures should not be less than 1/3 of the bolt diameter, but at least 3mm.4.3 When the cable is inlet through the terminal box, the cable entry should be sealed with elastic sealing gasket. The sealing ga

19、sket is made of rubber Shore-Hardness 4550 o. The material should withstand the aging test specified in EN60079-0：2004.The diameter of the cable brought into the terminal box shall conform to that of the bore in the sealing gasket. Several different concentric round slots are made in the sealing gas

20、ket and the values of the minimum outside diameter of cable corresponding to each round slot are marked on the outer surface of the sealing gaskets. The bear diameter of sealing gasket . The bear diameter of sealing gasket can be adjusted according to cable diameter. The coupler should be so tighten

21、ed that no gaps exist between the sealing gasket and the cable, between the sealing gasket and enter of terminal box and between the sealing gasket and chamber of gasket ring. Otherwise the flameproof property of the enclosure would be lost.4.4 the insulating parts of terminal bushing and connecting

22、 plate in the terminal box are made of insulating material being of Degree II tracking resistance.4.5 Earth: Earthing of motor is the important measurement to prevent leakage electric sparks to ensure safety. A steel or copper galvanized bolt uses as an earth terminal and also an earthing sign board

23、 fitted on distinct position of the motor enclosures.4.6 Flameproof parts the frame, the end shields, the shaft(rotor),the inner bearing covers, the bottom section of terminal box, the base of terminal box, the cover of terminal box, the terminal bolts ,the seal gasket, the terminal sleeve, see Figu
