Traction machine

Rope elevators are driven by the traction machine located in the rooftop machine room. There are geared- and gearless-type traction machines.
The gearless-type traction machine, through the latest inverter control, offers smoother acceleration and deceleration than the geared-type traction machine which uses a reducer.
Gearless-type traction machines also contribute largely to the miniaturization of devices in the machine room as well as improvements to energy efficiency and comfort.
