E-Type - Electromagnetic clutch without bearings

The basic model of electromagnetic clutch without bearings consists of stator body (1) with cast-in coil and connection cable (2) , the input drive hub (3) , and the armature disc (4) to which the return spring (5) is riveted.

When assembling, the stator body must be accurately centred on the input drive hub, otherwise the hub may rub on the stator body and cause damage to the clutch.

Depending on the size of the clutch, the installation must provide for an air gap of between 0.2 and 0.5 mm between the drive hub 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 return spring to the output component. When the armature disc is installed, it must remain free to move axially against the return spring.
