1MT0003 series ﬂameproof motors is newly designed totally enclosed fan cooling (TEFC) high efﬁciency motor. This series ﬂameproof motor completely meet the standard of IEC 60079- 0:2017/IEC 60079-1:2017 and GB/T 3836.1-2021/GB/T 3836.2-2021. The type of protection for this motor is Ex db IIB T4 Gb. And its efﬁciency fulﬁll efﬁciency grade IE3 (50Hz) of IEC 60034-30, and also Grade 3 efﬁciency of GB 18613-2020. This series products have excellent performance, safe and reliable to use, simple and ﬂexible installation, easy to maintain, low vibration, low noise.
1MT0003 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.
