YB3 explosion-proof motor overview
Yb3 series explosion-proof motor is a fully enclosed, self fan cooled, squirrel cage, flame-proof three-phase asynchronous motor developed by our company on the basis of reference industry unified design. The efficiency of Yb3 explosion-proof motor is in accordance with the energy-saving evaluation value standard in GB 18613-2012 "limited value of energy efficiency and energy-saving evaluation value of small and medium three-phase asynchronous motor", and the efficiency reaches the national level 3 energy efficiency standard.
The power level and installation dimensions of YB3 explosion-proof motors conform to the International Electrotechnical Commission (IEC) standards, and the corresponding relationship is the same as the German DIN42673 standard, which is conducive to the matching of export equipment and the replacement of imported equipment.
The explosion-proof performance of Yb3 series explosion-proof motor conforms to gb3836.1-2010 "explosive environment Part 1: General requirements for equipment" and gb3836.2-2010 "explosive environment Part 2: equipment protected by flameproof enclosure" d ", and also conforms to iec79-1, bs4683 and en50018. The explosion-proof sign is Exd Ⅱ BT4, which is suitable for places with explosive gas mixture.
On the basis of Yb3 explosion-proof motor, it can also be made into yb3-w outdoor explosion-proof motor, yb3-th wet tropical explosion-proof motor, yb3-thw outdoor wet tropical explosion-proof motor, yb3-ta dry tropical explosion-proof motor, yb3-taw outdoor dry tropical explosion-proof motor, yb3-t tropical explosion-proof motor, yb3-tw outdoor tropical explosion-proof motor and yb3-wf1 outdoor medium anti-corrosion explosion-proof motor .
