< -rDetails:
- < B(B) series fully enclosed self-fan-cooled squirrel-cage explosion-proof three-phase asynchronous motor is an updated product of the B series. It has the characteristics of high efficiency, energy saving, large starting torque, good performance, low noise, small vibration, high reliability, easy use and maintenance. The power level and installation dimensions comply with the standard and are consistent with the B series motors.
The explosion-proof performance of this series of motors complies with the requirements of B "Electrical Equipment for Explosive Gas Environments Part 2 Explosion-proof Type" and the International Electrotechnical Commission standards. It is made into explosion-proof types I, II, and IIIB respectively, and is suitable for use in coal mines. (non-mining working face) and dangerous places with explosive gas environments in factories of grade II, IIB, and temperature group ~.
The shell protection level of this series of motors is (see B/.).
The cooling method of this series of motors is (see B/3).
< rrr installation structure type
This series of motors has the following five basic installation structure types:
◆The base does not have feet, and the end cover has a flange (with screw holes).
◆B machine base has fast feet and a flange (with screw hole) on the end cover.
◆B machine base has feet and no flange on the end cover.
◆The base does not have feet. The end caps have flanges (with through holes).
◆B base has feet, and the end cover has flanges (with through holes).
The installation method of this series of motors (see B) is manufactured according to the table.
