Wolong YBU explosion-proof three-phase asynchronous motor is a special tunnel motor for tunnel boring machine, which is mainly used to drive the cutting section of cantilever-type roadheaders and other similar machines in coal mines.

Wolong Nanyang Explosion Protection company's YBU series flameproof three-phase asynchronous motors for tunneling machines use Morley's world-leading motor design and manufacturing technology, a full set of quality control systems, select high-quality raw materials and components, and adhere to Morley supervision in the design, manufacturing, and testing process to ensure its excellent performance and reliable quality, and accurately meet customer-specific requirements.

This series of Wolong Morley motors are widely used in coal mining, mineral mining and underground construction projects. They are suitable for places where there are explosive hazards of methane mixtures and coal dust in coal mines. The Wolong Morley motors can be used in conjunction with various mechanical equipment such as tunneling machines and shield machines to provide power support for the modernization of the coal industry in China motor manufacturers.

Wolong YBU motor can be customized according to customer requirements to Nanyang brand, Wolong brand, Schorch brand, etc.
