近年来,永磁同步曳引机相对于传统蜗轮蜗杆曳引机体积小、效率高、噪声低、能耗低、免维护的诸多优点,迅速成为各电梯制造商追逐的产品。据统计仅浦东新区2010、2011年新安装的永磁同步曳引机电梯已经占到新安装电梯数量的60%。而永磁同步曳引机节省建筑空间为无机房电梯的广泛应用奠定了基础。芬兰KONE的Mono Space、美国OTIS的Gen2都是运用永磁同步技术无机房电梯设计的经典。目前,浦东新区永磁同步曳引机无机房电梯保有量约占
In recent years, compared with the traditional worm gear hoist small size, high efficiency, low noise, low energy consumption, maintenance-free advantages, quickly became the product chasing the elevator manufacturers. According to the statistics, only Pudong New District 2010,2011 newly installed permanent magnet synchronous traction elevator has accounted for 60% of the number of newly installed elevators. The permanent magnet synchronous traction machine to save space for the building without machine room elevator laid the foundation for a wide range of applications. Mono Space of KONE of Finland and Gen2 of OTIS of the United States are classic examples of the design of machine roomless elevators using permanent magnet synchronous technology. At present, Pudong New Area Permanent Magnet Synchronous Machine without machine room elevator holds about
