Small Machine Room Elevator specification: Following the marked-oriented principle highly motivated by innovation 1.low noise low-speed synchronous motor reduces vibrations and eliminates noise completely. 2.more reliable the use of high quality materials and low cost running ensure the elevators run more reliably and for a longer service time . 3.comfort the VVVF vector-driven elevator has no peak value current and makes the elevator more steady and comfortable . 4.saving energy the highly efficient synchronous motor .the power consumption cost for power each year 5.maintenance the maintenance-free gearless traction machine does not need to be filled up with lubricating oil .and this can protect the environment
