The STYB series mining explosion-proof permanent magnet synchronous variable frequency motor (referred to as permanent magnet electric drum) is suitable for underground environments in coal mines with methane explosive mixtures and coal dust. The motor adopts Exd Ⅰ Mb explosion-proof grade and is a low-speed high torque permanent magnet synchronous motor specially designed for underground mining belt conveyors. The motor replaces the original asynchronous motor+reducer+drum drive mode and is placed inside the drum, achieving electromechanical integration; The permanent magnet synchronous electric drum directly drives the belt without any intermediate transmission links, improving system reliability, shortening the transmission chain, improving efficiency, and reducing failure rates.
Safe and reliable. Simple structure, high overload factor, vector control, basically maintenance free.
Low speed, high torque. The system has low rotational speed, high output torque, and operates smoothly.
Efficient and energy-saving. Adopting permanent magnet excitation, high efficiency and high power factor.
Easy to control and achieve unmanned operation.
