Electromagnetic clutches and brakes

SUCO electromagnetic clutches and brakes are used in construction machines, agricultural machinery, machine tools, pumps and compressors, centrifuges, belt conveyors and cleaning machines.

The working principles of electromagnetic clutches and brakes are very similar.

The stator body contains the field coil, which is a copper coil cast in synthetic resin. The clutch is activated by applying a direct current to the field coil. This creates a magnetic field, which electromagnetically attracts the armature plate towards the input drive hub with its friction lining, and so allows torque to be transmitted from the input side to the output. The axially-located output drive hub separates from the input side when the current is cut off . A return spring ensures that the armature plate separates from the input hub.

The stator body contains the field coil, which is a copper coil cast in synthetic resin. When current is applied a magnetic field is created, which attracts the armature plate to wards the friction lining, and so transmits a braking torque to the output hub. When the current is off, the return spring pulls the armature plate back to its original position.

Among many other applications, SUCO electromagnetic clutches and brakes are used in construction machines, agricultural machinery, machine tools, pumps and compressors, centrifuges, belt conveyors and cleaning machines.

Variants (Output side) of electromagnetic elements

With bearing-supported belt pulley

The output drive is a single-groove belt pulley which is supported on a hollow shaft.The pitch diameter can be supplied to the customer‘s requirements. Multiple-groove pulleys can also be supplied. Common groove forms are: SPA, SPB, SPZ, and Poly-V to DIN/EN.

With sprockets

A chain sprocket mounted on a bearing supported flange transmits torque on the output side.

With a flexible coupling

If an axial or angular misalignment is to be expected between two shafts, a flexible coupling can be attached.

Belt pulley on separate bearings

Here the output drive is a single or multiple groove belt pulley which is separately supported, not on the hollow shaft of the electromagnetic clutch. The pitch diameter of the pulley can be supplied to the customers' requirements. Common groove forms are: SPA, SPB, SPZ, or Poly-V or DIN/EN.

Clutch-brake combination (L-Type)

This model can be manufactured on request in the standard sizes.

Variante mit Kettenrad

Ein auf den gelagerten Flansch montiertes Kettenrad sorgt abtriebsseitig für die Drehmomentübertragung.
