Spring pressure brake to open electromagnetically for an drive mechanism rotates with a shaft, an electromagnet and a permanent magnet

摘要

Fitted concentric to a rotating part or a shaft (3), a pressure spring (PS) (7) rotates with the shaft and is supported on one side on a brake disk (BD) (2) and on the other side on the shaft, with both parts pressing apart. A spring pressure brake has an electromagnet (5). A permanent magnet (8) draws the BD and presses it onto a brake's surface (9) against the force of the PS.
