SUCO’s electromagnetic clutches, available from Norman G Clark , can be installed easily and feature straightforward designs. Similar to centrifugal clutches, electromagnetic clutches can only be used for dry running. SUCO’s electromagnetic clutches can provide reliable torque transmission without residual torque.
Once activated, the field coil of the electromagnetic clutch creates a magnetic field without the use of a collector ring. The magnetic field attracts the driven side towards the input drive hub. Friction linings between input and output sides of the electromagnetic clutches transmit the torque to the output drive. SUCO have two types of electromagnetic clutches namely, the E-Type electromagnetic clutch without bearings and G-Type electromagnetic clutch with bearings.
When assembling the E-Type electromagnetic clutch without bearings, the stator body must be centred accurately on the input drive hub, as the hub may rub on the stator body, causing damage to the clutch. Depending on the size of the clutch, the installation must provide for an air gap ranging from 0.2mm and 0.5mm, between the drive hub and the armature disc.
If a SUCO output drive hub is not used in the case of the E-Type electromagnetic clutch without bearings or G-Type electromagnetic clutch with bearings, it must be ensured that there are clearance holes to accommodate the rivet heads while installing the armature disc. The armature disc is centred by the screws, which hold the return spring to the output component. During installation, the armature disc must be free to move axially against the return spring.
