Specifications

ATEX explosion proof moor for mine
IEC: 63-355 ATEX certificate
Exd1 and Exd11BT4
ATEX YB2 YB3 YBK2 YBK3 YBF2explosion proof moor for mine

Feature and usage
YB2 ranges of three-phase induction motors are flame-proof motors obtained by renewal and generation-changing of YB ranges of motors. The performances of the products have come up to advanced international standards.
The motors have the advantages of higher efficiency, energy saving, higher locked-rotor torque, lower noise, smaller vibration, safe and reliable operation and beautiful appearance, etc. The outputs, mounting dimensions and their corresponding relationships comply with IEC standards.
YB2 series electric motors are designed and manufactured into explosion proof type and the explosion proof property conforms to China National Standards: GB3836.1-2000 Electrical Apparatus for Explosive Gas Atmospheres-General Requirements. GB3836.2-2000 Electrical Apparatus for Explosive Gas Atmospheres- Explosion proof Enclosure d and standards IEC79-1, BS4683 and EN50018. ExdI- safe for use in the non-mining surfaces of underground coal mines where the explosive mixtures of methane or coal-dust are present. ExdIIAT4 - safe for use in plants where the explosive mixtures of IIA Class, TI, T2, T3 or T4 are present. ExdIIBT4 - safe for use in plants where the explosive mixtures of IIB Class, TI, T2, T3 or T4 are present. ExdIICT4 - safe for use in plants where the explosive mixtures of IIC Class, TI, T2, T3 or T4 are present.

Oordering Informations

1. Please indicate the motor type, rated output, rated voltage, rated frequency, synchronous speed, Explosion proof Mark, mounting type, rotation direction(view from the shaft extension side)Use of the environment(indoor or outside)If the user havn't point out the rotation and environment, normailly we think is CW roration and used indoor.
2. When user have special requirments, For example: Dispose the stator, bearing explosion proof and bearing temperature sensors, space heater, Plateau use, specical frequency, mounting size change, special output, the user must, order can be confirm after signing the technical agreement with engneering department.
3. This range of motor can also be made into Variable-Frequency motors, the range of frequency of which is 0-100HZ, the output and overall dimensions should be confirm separately.
There are E x d I and ExdIIBT4 type in YB2 ranges of three-phase asynchronous explosion proof motor according to the requirement of the application. The performance of the safety of the products is confirming to the standard of GB3836.1-2000<<Electric Equipment for Using in the Explosive Gas Environment General Equipment, part1: Currency Need>> and GB3836.2-2000<<Electric Equipment for Using in the Explosive Gas Environment General Equipment, part2: Explosion-safe d>>, This ranges of products are suitable for the non-mining working area in underground mine or where there are the explosive gas mixture in factories
