Product Description
The YEJ series is an AC squirrel-cage electromagnetic brake motor. An electromagnetic spring-set brake is fitted on the non-driving end of the motor. When the power is switched off, the brake engages immediately to hold the load; when power is restored the brake releases automatically. A manual release lever allows the brake to be released by hand during maintenance or power failure.
YEJ brake motors are widely used on machinery and driving equipment that requires rapid and accurate braking, such as hoisting and lifting equipment, conveyors, machine tools, packaging machinery, textile machinery, logistics equipment and other machines that must stop and hold quickly and safely.
