YBK2 series flameproof three-phase asynchronous motors are special motors of mining for coal mine face machinery design, the base formed from sheet steel, wind shield, junction boxes, insulation structure to be taken to strengthen measures, mainly for poor working conditions of the coal mine.
This series of motors, explosion-proof performance in line with GB3836.1-2000 "explosive gas atmospheres - electrical equipment - Part 1: General requirements" and GB3836.2-2000 "explosive gas atmospheres - electrical equipment - Part 2: Flameproof" d '"the provisions made flameproof ExdI. Applies to methane or coal dust explosive mixture of dangerous places.
This series of motors there are special requirements in addition to the base, air cover, junction box, such as electrical performance, installation size, power rating, etc. YB2 series motors.
Motor main class for shell protection IP55, to meet GB/T4942.1 the regulations. Cooling method is IC411 to GB/T1993 provisions.
