1.2 Operation and principle

EM and EMER clutches-brakes are mono

friction disk and operate dry, they are activated
or inactivated electro magnetically. The clutch
and brake, in the EM type version, are
engaged alternately whereas in the EMER
type version, the clutch and brake are
engaged simultaneously.

The EMER type describes the clutch-brake

where the brake is electrically retained. When

the EMER’s clutch and brake are no longer

powered, the permanent magnet brake

immobilizes movement and acts as a parking
brake.
