WYJ250 series of permanent-magnet synchronous gearless traction machines are directly driven by a low-speed, high-torque, 3-phase permanent magnet synchronous motor, and has the advantages of low energy consumption, low noises, no pollution, and little maintenance.
These traction machines can be installed on the top of shaft way and the pit, with upward traction or downward traction, and have handwinding function.
This series of permanent-magnet synchronous gearless traction machines includes single wrap type and double wrap type, and roping factor is 2:1 for both types.
