Product Overview
The YBK3 series explosion-proof three-phase asynchronous motors are special motors designed for mining machinery in coal mines. The base is made of welded steel plate, and the fan cover, junction box, and insulation structure have been strengthened. The electrical performance, installation dimensions, and rated power are the same as YBX4.
The explosion-proof performance of this series of motors conforms to the provisions of GB/T 3836.1-2021 "Explosive atmospheres Part 1: Equipment general requirements" and GB/T3836.2-2021 "Explosive atmospheres Part 2: Equipment protected by "d" type flameproof enclosures" standards, and is designed and manufactured according to JB/T 9593.1-2015 "Technical conditions for explosion-proof three-phase asynchronous motors for coal mines Part 1: YBK3 series explosion-proof three-phase asynchronous motors for underground coal mines (base number 80-355)" standard.

CT4/High-pressure explosion-proof motor for dust
Explosion-proof dust motors are mainly used in places with combustible dust, such as pharmaceuticals, textiles (such as cotton fiber, flax fiber, chemical fiber, etc.), metallurgy (magnesium powder, aluminum powder, carbon powder), grain processing (such as wheat, corn, grains, etc.), feed processing (blood powder, fish powder), chemical fertilizers, tobacco, papermaking, synthetic materials (such as plastics, dyes), building materials, etc.
BT4 high-voltage variable frequency explosion-proof motor
Petrochemical (pumps, reactor agitators), natural gas (compressors, LNG storage tank pumps), textile coatings (fans, agitators), etc., in flammable and explosive gas environments, meeting the needs of high-power drive and energy saving.
General-purpose high-voltage three-phase asynchronous motor (YKK-YXKK)
Electric motors can be used to drive a variety of different machinery, such as fans, compressors, crushers, machine tools, transportation machinery and other equipment. They can also be used as prime movers in various industrial and mining enterprises such as mines, machinery manufacturing, petrochemical industry, and power generation enterprises, for driving blowers, coal mills, rolling mills, and hoists. When ordering, the purpose and technical requirements of the electric motor should be specified, and special designs should be adopted to ensure reliable operation.
High-voltage three-phase asynchronous motor (YKS, YXKS)
The Y, YX, YKS, and YXKS series of high-voltage three-phase asynchronous motors are typical representatives of high-power explosion-proof motors used in mines. With their high efficiency, reliability, and explosion-proof characteristics, they are widely used in mining, chemical, metallurgical, and power industries, and play a key role in large-scale machinery requiring high-voltage drives.
