Wolong Nanyang Explosion Protection always pursue the development goals of high efficiency, energy saving, environmental protection, smaller size, greater power, higher efficiency and more reliable performance. Wolong have introduced the research and development and process results of ATB Morley in Europe for more than 100 years, used leading analysis methods at home and abroad, and combined with Wolong Nanyang Explosion Protection company's long-term experience in the research and development and manufacturing of flameproof motors to develop the YBC series flameproof three-phase asynchronous motors for coal mining machines.

The flameproof performance of the motor is made into a flameproof type according to the provisions of GB3836.1-2010 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements" and GB3836.2-2010 "Electrical Equipment for Explosive Gas Environments Part 2: Flameproof Type , and its explosion-proof mark is "ExdIMb". It is suitable for places where explosive gas mixtures of methane or coal dust exist.

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