Gearless Elevators

Otis AC Gearless Elevonic® elevators offer answers to your most significant concerns – from performance and reliability to energy efficiencies and architectural compatibility.

AC Gearless Elevonic Elevators

The Otis Gearless Elevonic® system, with its AC variable-voltage, variable-frequency drive (AC VVVF), delivers the highest speeds and smoothest acceleration and deceleration. AC VVVF varies the voltage and frequency of the power source to provide precise speed control for a smooth, comfortable ride. Another benefit is the drive’s power factor of .95-plus, which offers energy savings during peak periods over DC drives. Its higher power factor allows for smaller mainline feeder sizes, and its reduced starting current demand allows the specification and application of smaller emergency generators. In addition, Otis’ patented Relative System Response Plus (RSR Plus®) and Elevonic control system provide the most effective dispatching in the industry. Two innovative features, the HPLIM® door system and LAMBDA® 3D entrance protection, are available with the Gearless Elevonic system. See the "Overview" profile for more information.
