A comprehensive solution developed for high-risk and narrow coal mine environments, integrating equipment drive and control technologies. It combines a permanent magnet synchronous variable frequency motor, reducer, and frequency converter into one unit. Leveraging the low-speed high-torque advantage of permanent magnet motors, together with the torque amplification of planetary reducers and precise control of frequency converters, it features a more compact structure and truly realizes permanent magnet direct-drive mechatronics integration.
