Detailed Product Descriptionunderground coal mine motor Certificate:ATEX CE Mark:\"ExdI\" or \"ExdIIBT4\" Power:0.12kw-355KW voltage:380v-1140v mine motors Model Meanings of Y B K 2-160 M 1 - 2: Y: Three-phase Induction Motor B: Explosion-proof/ Flameproof K: For Underground Mining 2: Second Design -160: Frame Size(Shaft Height) M: Frame Length Symbol (S, M, L) 1: Core Code (1, 2) -2: Poles Description of Explosion-proof Three-phase Induction Motor for Underground Coal Mining YBK2 series: According to the requirements of < Electrical Apparatus for Explosive Gas Atmosphere Part 1: General Request> and< Electrical Apparatus for Explosive Gas Atmosphere Part 2: Flameproof Enclosure \'D\'> of GB3836.2-2000, these Explosion-proof Three-phase Induction Motors for Underground Coal Mining YBK2 series can be made into explosion-proof motors. Applications of Explosion-proof Three-phase Induction Motor for Underground Coal Mining YBK2 series: 1)EExd I: This flameproof motor can be used in the underground coal mines where the explosive mixture such as methane or dust exists. 2) EExd II BT4: This explosion-proof motor we made in China is also suitable for used sites where the hazardous environment is classified into II Group, B Class, and Temperature T1-T4. Working Conditions of Explosion-proof Three-phase Induction Motor for Underground Coal Mining YBK2 series: 1) Ambient temperature will change according to different seasons, but it should not surpass 35º C (under coal mine) or 40 º C (factory), the lowest ambient temperature should be -15º C; 2) Local altitude should never surpass 1000m; 3) The maximum air relative humidity should be lower than 95% (while temperature keeps at 25º C)(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 25º C (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 95º C,
