Electromagnetic Clutches & Brakes

Supplier: Norman G. Clark

Electromagnetic clutches and brakes from SUCO are notable for straightforward design and ease of installation. Like centrifugal clutches, electromagnetic clutches and brakes can only be used for dry running. Reliable torque transmission without residual torque is guaranteed.

Once activated the field coil of the electromagnetic clutch creates a magnetic field using no collector ring. This magnetic field attracts the driven side towards the input drive hub. Friction linings between input and output side are transmitting the torque to the output drive.

Advantages of E-Type

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.

Construction and mode of operation of B-Type

The basic model of electromagnetic brake consists of stator body (1) with cast-in coil and connection cable (2) , and the armature disc (4) to which the return spring (5) is riveted.

Electromagnetic brake B-Type

The friction lining (3) is bonded directly to the stator body. 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.
