When standard torque ratings aren’t enough.
Stock magnetic couplings are for general-purpose pumping.
But sometimes you need a coupling engineered to the limit of physics.
Such as aerospace propulsion, high-pressure subsea systems, or heavy industrial braking.
We have deep expertise in Halbach Array manufacturing and Finite Element Analysis (FEA).
Can help you with custom magnetic transmission systems.
Deliver higher torque density, lower inertia, and extreme temperature resistance.
No matter you need to retrofit a 500kW chemical pump.
Or minimize a drive for a surgical robot.
We can engineer the solution from the magnetic circuit up.
Specialized Technologies We Engineer
A. Halbach Cylinder Couplings (High-Performance)
The Concept:
Standard radially magnetized tiles are backed by heavy iron.
We use Halbach Arrays for both the inner and outer rotors.
The Advantage:
Self-Shielding:
Eliminates the need for heavy back-iron.
Reduce rotor inertia by up to 40%.
Flux Concentration:
Focuses 100% of the magnetic field into the air gap.
Deliver 20-30% higher torque than a standard coupling of the same size.
Application:
UAV Propellers, Formula 1 / Motorsport KERS systems, and High-Speed Spindles.
B. Eddy Current Drives (Variable Speed & Soft Start)
The Concept:
A magnetic rotor on one side and a conductive Copper/Aluminum rotor on the other (Induction).
The Advantage:
Soft Start:
Allows the motor to spin up to speed before the load engages.
Reduce inrush current.
Variable Speed:
Torque transmission is proportional to slip speed (RPM difference).
Allow for non-contact speed control without a VFD.
Application:
Large HVAC Blowers, Conveyor Soft-Starts, and Braking Systems.
C. Linear Magnetic Couplings
The Concept:
Tubular arrays that transmit Push/Pull force rather than rotation.
The Advantage:
Allows you to move a piston or actuator inside a pressurized pipe from the outside.
With zero dynamic seals.
Application:
Valve actuation, sampling plungers, and pneumatic transfer systems.
Retrofit & Large-Scale Integration
Pump Retrofitting:
We can reverse-engineer existing mechanical seal pumps.
And design a “Drop-In” Magnetic Retrofit Kit.
Fit your existing housing, upgrading your equipment to seal-less operation.
Rather than replacing the entire pump.
Giant Industrial Couplings:
We can manufacture and balance massive couplings rated for 5,000 Nm to 10,000 Nm+.
Use segmented magnet assemblies and reinforced containment shells.
The Engineering Workflow (Simulation-First Design)
We de-risk your custom project through virtual validation.
1). Requirement Analysis:
You provide the Torque, RPM, Max Temp, and Space Envelope.
2). FEA Magnetic Simulation:
We simulate the Air Gap Flux Density and Torque Curve.
Ensure the design meets your safety factor (typically 1.3x to 1.5x breakaway torque).
3). Mechanical Stress Analysis:
For high-speed Halbach designs, we simulate the Hoop Stress on the carbon fiber.
Or Inconel sleeve to prevent catastrophic failure.
4). Thermal Analysis:
We calculate Eddy Current Losses (Watts) in the containment shell.
Ensure the system won’t overheat your fluid.
5). Prototype & Test:
We manufacture a pilot unit and test it on our dynamic torque bench.
Validate the simulation data.
