No Pollution Gearless Traction Machine

  Gearless Traction Machine Low Noise and No Pollution , WWTY5,  2:1  Ratio Product Description   This series of permanent-magnet synchronous gearless traction machines is directly driven by a low-speed, high-torque, 3-phase permanent magnet synchronous motor, and thus has the advantages of low energy consumption, low noises, no pollution, and little maintenance. These traction machines can be arranged for providing upward traction or downward traction, and have manual brake release function. This series of permanent-magnet synchronous gearless traction machines adapts single wrap, and roping factor is 2:1. Product Characteristics Traction ratio: 2:1 Rated capacity: 630, 800, 1000, 1150kg Rated elevator speed: 0.63,1,1.6,1.75,2.0ms Max. shaft load: 3000kg Applicable converter: 3 phase 400V Brake voltage: DC200V for Brake opening, and DC100V for brake holding Number of motor poles: 20 poles
