YBX3 series high efficiency flameproof motor

YB3 series flameproof three-phase asynchronous motor is an updated product of YB2 series. This series of motors is characterzied with high efficiency and energy saving, large temperature increase margin, small size, light weight, beautiful appearance, reliable operation, good performance, low noise, low vibration, and convenient use and maintenance. The efficiency index of this series of motors conforms to the motor energy efficiency level 3 described in GB18613-2012 Minimum allowable values of energy efficiency and energy efficiency grades for small and medium three-phase asynchronous motors. Its power grade and installation size conform to IEC standards and are the same as YB2 series motors. The explosion-proof performance of this series of motors meets the requirements of the GB3836.1-2010's Explosive Environment Part 1: General Requirements and the GB3836.2-2010's Explosive Environment Part 2: Equipment Protected by Explosion-proof Enclosure D. The explosion-proof Exd Ⅰ Mb, Exd Ⅱ AT4 Gb, Exd Ⅱ BT4 Gb, Exd Ⅱ CT4 Gb products are suitable for dangerous places in explosive gas environment with ⅡA, ⅡB, ⅡC and temperature groups of T1 ~ T4 respectively in underground coal mines (non-mining faces) and factories. On the basis of YB3 motor, it can also be made into YB3-W outdoor model, YB3-TH indoor humid model, YB3-WTH outdoor humid model, YB3-WT outdoor tropical model and YB3-WF1 outdoor model, which are suitable for using in the medium anti-corrosion climate environment.
