Tractionmachine adopts WYT serial permanent-magnet synchronous gearless tractionmachine which is made of high performance neodymium-borum material, works underthe drive of the frequency converter with the function of synchronous servocontrol, through the coaxial installed high precision encoder to form theclosed loop control system. It can obtain excellent low speed large momentfunction. SanyoVF320 elevator WYT permanent-magnet synchronous motor also has the followingfeatures. 1.Save energy resources. Compare withthe traditional worm-wheel worm shaft traction machine, it can save 40% energy. 2.Reduce vibration and noise. 3.Maintenance-free. 4.Small volume. The outer size is only672mm×331mm×830mm, 420kg. 5.The normal work of thepermanent-magnet synchronous traction machine doesnt cause harmonicsinterference. Its counter emf is also sine wave. It not only doesnt pollutethe power supply system but also can compensate the no-work power which isneeded by the power supply system perceptual load and raise the power factorwhen it excites.
