Both geared and gearless traction elevators are driven by alternating current (AC) or direct current (DC) electrical motors. In geared elevators, a worm gear is used to control the mechanical movement of the car. This is done by rolling steel hoist ropes over a drive sheave. Geared machines can reach speeds up to 500 feet per minute.
