Electromagnetic brakes

The stator body must be installed so that it is concentric with the output side.

Depending on the size of the brake, the installation must provide for an air gap of between 0.2 and 0.5 mm between the friction lining and the armature disc.

If a SUCO output drive hub is not used, it is important to ensure that there are clearance holes to accommodate the rivet heads, when installing the armature disc. The armature disc is centred by the screws which hold the spring disc to the output component. When the armature disc is installed, it must remain free to move axially against the return spring.

B-Type Electromagnetic brakes

Construction and mode of operation

The basic model of electromagnetic brake consists of stator body with cast-in coil and connection cable, and the armature disc to which the return spring is riveted. The friction lining is bonded directly to the stator body.
