ATEX explosion proof moor for mine
IEC: sixty three-355 ATEX certificate
Exd1 and Exd11BT4
ATEX YB2 YB3 YBK2 YBK3 YBF2explosion evidence moor for mine
Attribute and usage
YB2 ranges of a few-section induction motors are flame-evidence motors obtained by renewal and technology-changing of YB ranges of motors. The performances of the goods have occur up to sophisticated worldwide standards.
The motors have the benefits of increased effectiveness, strength conserving, greater locked-rotor torque, reduced noise, smaller vibration, safe and reputable operation and beautiful appearance, etc. The outputs, mounting dimensions and their corresponding interactions comply with IEC expectations.
YB2 collection electric powered motors are developed and made into explosion proof variety and the explosion evidence residence conforms to China National Specifications: GB3836.1-2000 Electrical Apparatus for Explosive Fuel Atmospheres-General Requirements. GB3836.2-2000 Electrical Apparatus for Explosive Gasoline Atmospheres- Explosion evidence Enclosure d and expectations IEC79-1, BS4683 and EN50018. ExdI- risk-free for use in the non-mining surfaces of underground coal mines exactly where the explosive mixtures of methane or coal-dust are current. ExdIIAT4 – risk-free for use in vegetation the place the explosive mixtures of IIA Course, TI, T2, T3 or T4 are existing. ExdIIBT4 – safe for use in crops exactly where the explosive mixtures of IIB Course, TI, T2, T3 or T4 are current. ExdIICT4 – protected for use in plants the place the explosive mixtures of IIC Course, TI, T2, T3 or T4 are current.

one. You should point out the motor type, rated output, rated voltage, rated frequency, synchronous velocity, Explosion evidence Mark, mounting type, rotation path(check out from the shaft extension side)Use of the surroundings(indoor or outdoors)If the user havn’t point out the rotation and surroundings, normailly we think is CW roration and utilized indoor.
2. When consumer have special requirments, For instance: Dispose the stator, bearing explosion proof and bearing temperature sensors, place heater, Plateau use, specical frequency, mounting dimension change, specific output, the user should, purchase can be validate soon after signing the specialized arrangement with engneering department.
three. This variety of motor can also be manufactured into Variable-Frequency motors, the range of frequency of which is -100HZ, the output and total proportions must be affirm individually.
There are E x d I and ExdIIBT4 type in YB2 ranges of a few-section asynchronous explosion evidence motor according to the necessity of the software. The functionality of the safety of the goods is confirming to the standard of GB3836.1-2000<> and GB3836.2-2000<>, This ranges of products are appropriate for the non-mining wor ept spot in underground mine or the place there are the explosive fuel combination in factories
