Magnetic Disc Clutches


The contactless transmission of torque through claddings of various kinds allows for example:

  • Power transmission for pumps, agitator assemblies and compressors into closed liquid filled containers
  • Power transmission for ventilators in closed containers with gas, steam or similar
  • Power transmission for underwater robot- handling
  • Transmission of round scale displays into a different medium
  • Avoidance of motor vibration transfers
  • Uncoupling of load influences at weighing processes
  • Standard working temperature range
    from -40 to +140°C (special execution
    up to +280°C)

The magnetic discs can also be parts in hysteresis brakes.

All magnetic disk couplings are made of stainless steel material: 1.4005 / 1.4305 (1.4401 on request)
All laser-welded magnetic disk couplings are made of 1.4401.

How Magnetic Disc Couplings Work:

Disk Type Couplings consist of two opposing discs equipped with powerful rare earth magnets. The torque applied to one disc is transferred through an air gap to the other disc.
Because of its simple flat design, you can have angular misalignment of up to 3° (Fig. 1) or parallel misalignment up to 1/4” (Fig. 2) and still transmit nearly full rotational torque.
You can also implement an inexpensive flat barrier to separate the atmospheres or fluids surrounding the two discs. This is our simplest and most versatile application.
The magnetic discs can also be parts in hysteresis brakes.
