Wolong YBBP series (water-cooled) uses 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. Wolong YBBP series are used to drive equipment that requires stepless speed regulation and are used in conjunction with frequency converters. Wolong YBBP series have the advantages of high efficiency, high stall torque, high reliability, low stall current, and strong overload capacity. Wolong YBBP series are well-made, have excellent performance, reliable operation, beautiful appearance, and are easy to use and maintain.

Wolong YBBP series 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.

Product Detail

The three-phase asynchronous motor for conveyor is a special motor for driving the flexible scraper conveyor, belt conveyor or other equipment in the underground mining face of coal mine. Its design adopts British Morley technology to provide customers with high-quality coal special motor made in China with European process design.
