SIMOTICS XP 1MB series flameproof motors in Siemens newly designed three-phase asynchronous for global market. It’s fully enclosed, self - fan - cooled high efficiency motor. This series flameproof motor completely meet the standard of IEC60079- 0:2017/IEC60079-1:2017 and GB3836.1-2010/GB3836.2-2010. It is designed for "Ex d ll C T4 Gb" grade as standard and certified by CQST, The efficiency rating reaches IE3 of IEC 60034-30, which is in accordance with Grade 2 efficiency standard of China GB18613-2012.
The products combined with Siemens hundred years design technology, the production equipment of this series adopt advanced CNC machine tools, based on Siemens advanced
insulation structure design and manufacturing process, use high quality cold-rolled silicon steel sheets and high quality parts with strict quality control. This series products have excellent
performance, safe and reliable to use, simple and flexible installation, easy to maintain, low vibration, low noise.
1MB series high-efficiency flameproof motors can be widely used in petroleum, chemical industry, oil and gas and other hazardous areas and places.These motors are designed such that an explosion within the housing cannot result in an explosion in the environment. The energy that is generated internally by an explosion is dissipated in the so-called “flameproof enclosure”so far that the energy is no longer sufficient for ignition outside the casing
