| 1. Brief Description of IEC Explosion-proof/Flameproof Motor ExdIICT4 IE2/EFF1 YB3 series of flameproof three-phase induction motors type of H63~355 are latest products developed by our company combining with home and abroad electromagnetic structure, technique and material etc based on YB and YB2 series of motors. This series of motors have many merits such as high-efficiency, energy conservation, big margin of temperature rise, long service life, excellent performance, low noise, advanced explosion-proof structure, high reliability and convenient operation and maintenance etc. The efficiency index of this series motors confirms to the energy efficiency grades 3 of specified in GB18613-2012 Minimum allowable values of energy efficiency and the energy efficiency grades for small and medium three-phase asynchronous motors. Power class and the installation dimensions accord with IEC standard , also completely in the same way as YB and YB2 series three-phase induction motors. 2. Energy Effective Rate of IEC Explosion-proof/Flameproof Motor ExdIICT4 IE2/EFF1 This explosion-proof/flameproof motor meets IEC standard energy standard IE2 or European energy standard EFF1 Energy Description: IE3IE2IE1 EFF1EFF2EFF3 3. Working Conditions of IEC Explosion-proof/Flameproof Motor ExdIICT4 IE2/EFF1 1) Ambient temperature will change according to different seasons, but it should not surpass 35 (under coal mine) , 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) 4) The bearing max temperature should not surpass 95. 4.Order of IEC Explosion-proof/Flameproof Motor ExdIICT4 IE2/EFF1 1) Rated voltage is 380/660V and can generate specific voltage 2) Rated frequency is 50Hz and can also be 60Hz. 3) Protection: IP55 4) Insulation Class:F or H 5) Duty:S1 continuous 6) Cooling:IC411 7) Housing:Stainless Steel 8) ZWZ bearing as standard and other brand bearing can also be required. 5 Data and Specification of IEC Explosion-proof/Flameproof Motor ExdIICT4 IE2/EFF1 Download PDF Files 6 Mounting and Dimension of IEC Explosion-proof/Flameproof Motor ExdIICT4 IE2/EFF1 Download PDF Files |
