Gearless ACPM Machines

Gearless ACPM Machines

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.
