  • Gearless AC Machines

    Gearless AC Machines Frame 450, 460, 470, 500, 700, 800, 900 Series

    Compact design, high efficiency and extreme reliability have confirmed the Imperial Electric Gearless ACPM Machines to be a favorite in the industry. Models available: Frame 450 Series, 460 Series, 470 Series, 500 Series, 700 Series, 800 Series and 900 Series.

    Unlike traditional induction motors that lose efficiency at lower speeds, Imperial Electric gearless AC machines provide unusually capable low speed, high torque operation — and consume up to 40% less power than traditional asynchronous motors. Imperial Electric gearless AC machines are also noticeably quieter than the competition and are nearly maintenance-free.

    Imperial Electric machines are known for durability and reliability. Imperial Electric gearless AC machines use rugged cast iron frames protecting a totally enclosed, self-cooling motor. Machine brake and sheave assemblies are removable and replaceable — features that will provide cost savings over long years of service.

    Imperial Electric provides gearless AC machines in seven frame sizes — serving car capacity ranges from 1,250 to 8,000 lbs. at speeds from 100 to 2,000 fpm (feet per minute). The 470 series has the capacity to lift 1,375 to 4,000 lbs. at speeds up to 500 fpm with 2:1 roping. The 500 series has the capacity to lift 2,000 to 4,500 lbs. up to 700 fpm with 1:1 roping or 2,000 to 8,000 lbs. up to 700 fpm with 2:1 roping. The 700/800 series has the capacity to lift 2,000 to 5,350 lbs. up to 1,600 fpm with 1:1 roping or 3,000 to 10,000 lbs. up to 800 fpm with 2:1 roping. The 900 series has speeds up to 2000 foot per minute (10 m/s) for up to 8,000 lbs. car capacity for 1:1 roped applications and 1000 foot per minute (5 m/s) for up to 16,000 lbs. car capacity for 2:1 roped applications.

    With the introduction of gearless AC machines to complement industry-leading, gearless DC machines, Imperial Electric boasts the most comprehensive gearless machine line in the elevator industry. For more series-specific information, please visit Imperial Electric.

  • MCE Geared Machines

    94MB Geared Traction Machine

    Motion Control Engineering is now bringing geared traction machines to the North American elevator market with the introduction of the MCE 94MB Geared Traction Machine.

    The 94MB is the perfect solution for mid-rise applications that will benefit both modernization and new construction projects. It has a significantly smaller footprint and requires simpler site preparation. The compact design and reduced weight allow for easy handling, installation and maintainability.

    Geared Traction Machine - TM Series

    The TM Series (TM21, TM26 and TM35) geared traction machine from Motion Control Engineering (MCE) 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.
