Geared Traction Machine - TM Series

Models TM21, TM26, and TM35

The TM Series geared traction machine from Imperial Electric is a compact, easily installed and
serviced, superior quality solution for medium speed, high capacity elevators.

The streamlined design of the TM Series allows significant weight reduction without sacrificing durability or frame rigidity. The TM Series slow shaft uses tapered roller bearings that require no periodic grease lubrication, assuring reliable performance over time without the risk of efficiency loss or failure that can occur on other machines when bearing lubrication is overlooked. The TM Series worm shaft, using the recommended geared machine oil, employs a unique design that protects the shaft. The TM Series traction sheave is fitted with shrink-fit sheaves.

The TM Series uses AC VVVF motors from Imperial Electric. Imperial motors use cast iron construction and hot rolled steel shafts, achieving a level of performance and dependability you can trust through long years of service. Imperial motors are renowned for quiet performance and long service life.
