Motor Description

YB2 series High Voltage Flame-proof Three-phase Asynchronous Motor (Frame Size. H355~560) is accord with Chinese Flame-proof standard GB/T 3836.1 and GB/T 3836.2. The coolant mode is IC411, and the Flame-proof mark is Ex db ⅡB T4 Gb, which can replace Ex db ⅡA T1 Gb 、Ex db ⅡA T2 Gb、Ex db ⅡA T3 Gb、Ex db ⅡA T4 Gb、Ex db ⅡB T1 Gb、Ex db ⅡB T2 Gb、Ex db ⅡB T3 Gb.

This series of motor has advantages, such as excellent Flame-proof property, high reliability, compact structure, safe, environment protection, low vibration, low noise, easy to install and maintain. And it can replace YB560~710 series (IC511 tube cooling structure) high voltage Flame-proof three phase asynchronous motor.

This series of motor can be widely applied to drive different kinds of general machines, such as compressor, water pump, crusher, windlass, centrifuge, cutting machine, conveyors and so on. YB2 series high voltage Flame-proof three-phase asynchronous motor can always provide excellent driving power and meet well the customer’s need no matter in indoor, outdoor, plateau, damp-heat type or other working conditions.
