Recently, the 1200kW permanent magnet semi-direct drive unit independently developed by China Coal Science Tiandi Benniu successfully completed joint debugging in the mine.

The permanent magnet semi-direct drive is a new type of drive in the industry, which integrates the permanent magnet motor, deceleration transmission unit and tight chain device to achieve a highly integrated design, and has the characteristics of green efficiency and high reliability. After two years of in-depth research and technical research, the transmission R & D team successfully broke through a series of technical problems such as space compact, energy efficiency optimization and mechanical structure innovation, invented the permanent magnet drive part brake device and tight chain control method, designed the axial compact planetary transmission unit and efficient cooling gear transmission unit box.

The successful development of permanent magnet semi-direct drive has added impetus to further improve the performance of transmission products and expand diversified markets. China Coal Technology Tiandi Benniu will continue to increase investment in research and development, develop more high-quality, efficient and high-quality products, and gather energy for the Group company to build into a world-class scientific and technological innovative enterprise with global competitiveness.
