Bistable Clutches - Low Energy Solution

Energy-optimized switching

KEB bi-stable clutches, also called flip-flop clutches, maintain the switching status - open or closed - without any additional power feed.

Switching is effected by a short power pulse designed solely to change the switching status. Compared to conventional clutches, this provides energy saving of up to 99% depending on power-on time.

Bi-stable KEB clutches ensure maximum energy efficiency and are ideally suited to use in air-conditioning compressors, etc., or doors.
