Achieve ultra-smooth, wear-free torque control with our Precision Hysteresis Couplings.
Standard synchronous magnetic couplings can ‘ratchet’ or cog when overloaded.
Hysteresis couplings use a specialized semi-hard magnetic alloy.
They generate constant, drag-free torque even during 100% slip.
This asynchronous behavior makes them the industry standard for:
– Bottle Capping Headsets, Wire/Web Tension Control, and Precision Torque Limiting.
There is no mechanical friction (like felt or friction pads).
And no magnetic cogging, our units deliver identical torque values after millions of cycles.
Eliminate the need for constant maintenance and recalibration on your production line.
Engineering & Manufacturing Capabilities
Hysteresis Material Science:
The core of this technology is the hysteresis disc (a specialized alloy that resists changes in magnetization).
We build specific heat-treatment profiles for our alloys.
Maximize the Energy Product (BHmax).
Ensure stable torque output across a wide RPM range.
Cog-Free Operation:
We utilize multipole geometric optimization.
Ensure the transition from ‘Drive’ to ‘Slip’ is imperceptible.
This is critical for fine wire tensioning.
Because even a micro-pulse of torque variation can snap the wire.
Thermal Dissipation Management:
Continuous slip generates heat (Eddy Currents + Hysteresis Loss).
We design our housings with integrated cooling fins.
Plus air-flow channels to dissipate heat efficiently.
Prevent thermal torque fade during high-speed operation.
Customization Options
A. Capping Headsets (The Bottling Industry)
Adjustable Torque:
We manufacture magnetic headsets with an internal adjustment mechanism.
Rotate the outer ring.
You can vary the magnetic overlap.
Change the application torque (e.g., from 1 Nm to 3 Nm) to suit different cap sizes without changing parts.
Interchangeability:
Compatible chucks for major capping machine brands (e.g., Zalkin, Arol, Alcoa).
B. Tension Brakes (The Winding Industry)
Constant Tension:
Designed for “Pay-off” stands.
The spool can empty and spin faster.
The Hysteresis brake will provide constant back-tension to keep the wire, foil, or film taut.
Range:
From delicate <0.05 Nm brakes for optical fibers to robust 10 Nm units for cable stranding.
C. Mounting & Integration
Shaft-to-Shaft:
Standard coupling format for connecting a motor to a load limit.
Component Sets:
We supply the Hysteresis Disc and Magnet Rotor separately for OEMs.
Integrate the technology directly into their own rollers or spindles.
