Explosion-proof brushless dc motor is what? Which places need to use explosion-proof brushless dc motor? Encyclopedia | | brushless dc motor brushless dc in southern anhui province

First of all, what is explosion-proof brushless dc motor? Explosion-proof actual brushless dc motor for flame-proof brushless dc motor, it is different from the ordinary environment using brushless dc motor structure, can prevent external brushless dc motor of gas and dust into the brushless dc motor structure, or while entering, can also occur in its internal short circuit of the fire cases, will not fire out casing outside ignition of combustible gas and dust that exist in the surrounding environment. Which places need to use explosion-proof brushless dc motor? Explosion-proof brushless dc motor is widely used for flammable gas, dust, open flame or hot objects can burn even explosion environment, such as coal, paint shop, flour mills, transportation and storage of flammable gas and liquid mechanical and warehouse ( Such as oil tank truck, oil and natural gas delivery system, gas stations and liquefied gas station, etc. ) Combustible gas chemical workshop ( Such as ammonia production workshop) 。 Production of brushless dc motor in the south of anhui explosion-proof brushless dc motor: 1, YB3 series flameproof three-phase asynchronous motor YB3 series flameproof three-phase asynchronous motor is on the basis of YB2 flameproof brushless dc motor in accordance with the GB19613 - Level 3 of the 2012 energy efficiency standard specification designed a new type of motor. Applies to contain gases such as methane or coal dust in the coal mine ( The mining working face) （ Exd我) And factories, Exd II AT4、dIIBT4） , and contain II class A and class B T1 ~ T4 group of combustible gas or vapor form explosive mixtures with air. 2, YBX3 super-efficient series flameproof three-phase asynchronous motor YBX3 super-efficient series flameproof three-phase asynchronous motor is in YB3 explosion-proof of brushless dc motor based on the research and development of new type flameproof motor, according to the GB19613 - Level 2 of the 2012 energy efficiency standards for new motor specification design completed. Applies to contain gases such as methane or coal dust in the coal mine ( The mining working face) （ Exd我) And factories, Exd II AT4、dIIBT4） , and contain II class A and class B T1 ~ T4 group of combustible gas or vapor form explosive mixtures with air. 3, YBF2 series fan with flameproof three-phase asynchronous motor YBF2 series fan with flameproof three-phase asynchronous motor is designed according to the characteristics of axial flow fan Lord dedicated motor, and according to the particularity of the fan, the bearing structure of the brushless dc motor and the way of qualification of the special design. 4, YFB2 dust explosion-proof series three phase asynchronous motor YFB2 dust explosion-proof series three phase asynchronous motor is the product used in combustible dust environment. Suitable for explosive dust were there in the factory Fiber) 10 area 11 district dangerous situations. Its temperature classes T1 - T4 group situations; But does not apply to situations such as gunpowder, explosives; Also does not apply to exist of flammable gas and combustible dust explosion hazard. 5, YBK2 series coal mine with series YBK2 flameproof three-phase asynchronous motor in the coal mine with flameproof three-phase asynchronous motor is suitable for the coal mine sites containing methane and coal dust. 6, YBS series scraper conveyor with YBS flameproof three-phase asynchronous motor series scraper conveyor with flameproof three-phase asynchronous motor is suitable for the coal mine driving scraper conveyor, belt conveyor, scraper reproduced machine, such as coal mining machinery, with frequent starting, overload ability, good protective performance.
