The passenger elevator with small (without) machine room driven by the new generation of permanent magnet synchronous gearless traction technology has the following outstanding advantages:
Green and environmental protection
The host adopts the closed bearing structure which has no requirement for lubricant replacement on fully-closed bearing. While achieving maintenance-free of the service elevator, pollution by grease can also be avoided.
High efficiency and energy-saving
The host requires no excitation, the starting current is very small and the transmission efficiency is extremely high. Thus, it can save energy by more than 30% as compared with traditional traction machine so as to significantly reduce the cost of daily use of the passenger elevator;
Since the host has compact structure and is light and small, the user may select compact machine room layout (small machine room) or directly install the host inside the hoistway (without machine room) according to their needs, thus saving construction area and cost for the maximum.
Safe and comfortable
Replace the traditional traction machine's worm reduction box by the new coaxial rotating structure, thus essentially eliminating operation noise and vibration to greatly enhance the comfort of passengers in the service elevator.
