• Working principle: The housing is designed and manufactured according to the specified conditions, which can prevent dust from entering the motor housing or even if it cannot completely prevent dust from entering, the amount of dust entering does not hinder the safe operation of the motor, and the accumulation of internal dust is not easy to cause ignition hazards, and the motor will not cause explosion of explosive dust mixtures in the surrounding area when used.

• The high-efficiency dust-proof explosion-proof three-phase asynchronous motor is a fully enclosed, self-fan-cooled high-efficiency motor. The efficiency of this series of products meets the requirements of GB18613-2020 energy efficiency level 3 standard. This series of products uses Siemens design technology, has excellent performance, safe and reliable use, low vibration, low noise, etc., and meets environmental protection requirements; its production equipment uses advanced CNC machine tools, uses Siemens advanced insulation structure design and manufacturing technology, uses high-quality cold-rolled silicon steel sheets and high-quality bearings that have undergone strict quality inspection and control.

• The explosion-proof performance of Beide dust explosion-proof motors complies with the provisions of GB/T 3836.1-2021 "Explosive Atmospheres Part 1: General Requirements for Equipment" and GB/T 3836.31-2021 "Explosive Atmospheres Part 31: Equipment Protected by Dust Ignition-Proof Enclosure "t"", and is applicable to Zone 21 and Zone 22 in explosive dust environments

• Explosion-proof grade: Ex tb IIIC T130 ℃Db
