Custom brakes are the smallest on the market

Warner Electric, part of Altra Industrial Motion, has developed the X-Small brake range of electrically released, spring-set holding brakes which are designed to offer the same performance capabilities of similarly sizes permanent magnet solutions.

The X-Small brakes are designed primarily for engaged / disengaged holding applications – such as seat adjustment on an aeroplane – though they can provide a low cycle rate stopping action in emergency situations. As they are electrically released Warner claims they will remain reliably engaged in the event of a power failure, which suits them to applications where the integrity of the holding force is necessary.

The range consists of six standard sizes which range from 22 to 33.5mm diameter (30 to 100g) and offer up to 50Ncm of static torque. However, Warner Electric also customises a bespoke adaptor flange for each customer to help make sure the brakes mount properly.
