Chuck Control Units for electromagnets


Description and function

Chuck control units convert the AC (alternating current) input from the power line into DC (direct current) output to “feed” the coils of the chuck.

A microprocessor based control board in the unit allows adjusting the clamping force of the magnet and also automatic demagnetization. An important function lies in operator safety: The chuck control prevents the machine from running if the holding force of the chuck is too low.

Variable holding force

The holding force can be adjusted by a rotary button on the remote control station which controls the output voltage.

A lower output voltage also helps to reduce the warming up of the coils inside the chuck in order to work cooler and obtain a higher accuracy.

Automatic demagnetization

Both the magnetic chuck and the workpieces can be completely demagnetized.

Depending on the type of steel, different demagnetizing programs can be selected.

Safety

Apart from the fact that our control units comply with the IEC electrical standards they also comply with the provisions of the European Machinery Directive 2006/42/EC. A safety contact inside the unit prevents the machine from running if the magnet is not switched on or if the holding force is too low.

Available control units

For electromagnetic chucks we offer 2 types of control units M and MT (with transformer)

and in 2 versions:

  • protection class IP00 for integration in the machine’s control cabinet
  • built into steel enclosure, protection class IP54

 

Standard output voltage: 110 VDC

Input voltage: 230 VAC

Choosing the correct control unit depends upon the magnet wattage or the total wattage of multiple magnets.
