YBBP series (water-cooled) explosion-proof variable frequency speed regulation Three-phase asynchronous motor (frame size 355~560)

Application

YBBP series (water-cooled) explosion-proof variable frequency speed regulating three-phase asynchronous motors use Morley’s world-leading motor design and manufacturing technology and a full set of quality control systems. They use high-quality raw materials and components, and insist on Morley supervision in the design, manufacturing and testing process to ensure their excellent performance and reliable quality, precisely meeting customers’ specific requirements. They are used to drive equipment that requires stepless speed regulation and are used in conjunction with frequency converters. They have the advantages of high efficiency, high stall torque, high reliability, low stall current, and strong overload capacity. The products are well-made, have excellent performance, reliable operation, beautiful appearance, and are easy to use and maintain.

This series of motors are suitable for the coal industry and for places where explosive gas mixtures of methane or coal dust exist. They can drive various mechanical equipment such as flexible scraper conveyors, belt conveyors, crushers, pumps, etc. on the mining working face of underground coal mines.
