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.
With a compact, sleek design and extreme reliability, it is no wonder that the Imperial Electric Gearless ACPM Machines are a favorite in the industry. All models are UL/CSA CUS Certified.
This series features a smaller diameter, lighter weight, and with all of the power you need. Our ACPM 450 Series, a “Barrel” style machine, is compact and green with no oil lubricants and is low-noise. Notably, the 450 series offers precise acceleration, deceleration, and contract speed control with cooler overall operation. These Barrel style machines are for new construction, machine room less (MRL), or for modernizing geared machine replacements.
