Elevator Lift Traction Machine
Dyj series traction machine for lift, developed by famous specialist in China is one of the best machine for aught I konw, specially designed for machine-roomless lifts or top-positioned machine-room lifts, is installed by 2:1 hanging. The design has up to 37 types, adn both pmsm orinduction motor is suitable for prime mover input. Some own characters are listed as follows:A, thin(down to 228mm) b, light(less than 350kg) c, high efficiency(overall efficiency for electro-mechanical up to 90%) d, easy to install e, low noise f, no maintenance(positive feedback automatically tensioning, so belt never slipping) g, highly reliable.Name branded narrow-v driving belts are produced conforming to international standard, and because a newly invented, positive feed-back precious-controlling auto-tensioning technology is adapted, belt sliding problem is absolutely avoided, so the dyj machine requires no maintenance. The belt have an operation life span of 20 years, without any maintenance; therefore operation cost is dramatically reduced, among other advantages such as smooth operation and low noise.Bearings are produced by special bearing-steel, with designed working life span of 30 years. Due to good workmanship of precise machining, precise assembling and reliable sealing, no refilling is required during bearing`s working life.Compared to traditional traction machine with gearless pmsm, the dyj system shall be 10% more efficient when high speed pmsm is adapted, it is also evidently more efficient even if induction machine is adapted. Therefore, the required capacity of electrical driving system such as inverter, breaker, contactor and so on is reduced by at lease one grade, and since belt drive system has no lubrication requirement like traditional gear system, we would like to call our system green machine.The tolerance and breakdown of the feedback system of traction machine, which is me most critical problem of traditional traction, is ehminated in our design, since we adapted shockproof, anti-emi, thermal endurance high-reliability encoder in dyj and installed by patented technology.Dyj has equipped with double redundancy disc brake system, the clearance can be auto-regulated by magn-etic levitation force, the torque can hold the line by nonlinear spring even the friction lining has abrasion, the friction surface can self-adapting it`s position universally, the action noise is very low so suited to machine-roomless use, and the brake disk is coaxial and integral with traction sheave, so it has no further use for the upward overspeed protection equipment.--------------------------------------------------------------------------------* this member`s information has not been authenticated or verified by alibaba or any third party.
