Y2EJ

Y2EJ three-phase asynchronous motors with electromagnetic brake

Y2EJ is a totally enclosed fan-cooled squirrel-cage motor built on the base series with an added DC electromagnetic brake. Frame sizes 71–280 provide fast, accurate stopping with low noise and vibration. Typical uses are hoists, electric valves, machine tools, woodworking and printing machines and geared drives.
