Product Description
This explosion-proof three-phase induction motor for ventilation blower (frame size 63-355) we manufactured in China can be made into a flameproof motor according to the application requirements of GB3836.1-2000 < Electrical Apparatus for Explosive Gas Atmosphere Part 1: General Request> and GB3836.2-2000 < Electrical Apparatus for Explosive Gas Atmosphere Part 2: Flameproof Enclosure u2018Du2019> of GB3836.2.

1) EExd I : This flameproof motor is used in the underground coal mines where the explosive mixture such as methane or dust exists.

2) EExd II BT4: This explosion-proof motor is suitable for factories where the hazardous environment is classified into II Group, B Class, and Temperature T1-T4.

1) Ambient temperature will change according to different seasons, but it should not surpass 35(under coal mine) or 40 (factory), the lowest ambient temperature should be -15;

2) Local altitude should never surpass 1000m;

3) The maximum air relative humidity should be lower than 95%(while temperature keeps at 25)(under coal mine) or the monthly maximum mean relative temperature of the most humid month should be 90%, and meanwhile the lowest temperature of this month should not over 25(factory).

4) Rated voltage should be 380V, 660V, 1140V, 380/660V and 660/1140V;

5) Rated frequency should be 50Hz;

6) Working mode of the motor is S1 continuous duty, full-voltage start-up is available;

7)Electromotor applies F-class insulation, and raise of stator temperature(resistance method) is checked according to 80K (among which NO.2, 4 of 315L and No.355 are checked according to 105K)

8)Temperature (use thermometers)of motor bearings should be lower than 95.
