Torque & speed
Share running, start-up and overload conditions.
Magnetic Couplings
Non-contact torque transmission for separated mechanical systems. Review torque, working gap and containment conditions together.
Application review notes
Coupling performance depends on more than magnet strength. We review required torque, speed, working gap, containment materials and temperature together, helping define an assembly and verification method suited to the operating environment.

Review This ConfigurationSelection identifies the review scope. Materials, ratings and acceptance criteria remain subject to engineering confirmation.
A good fit when
- Pumps, mixers and drives that need a sealed process boundary
- Applications where eliminating a dynamic shaft seal reduces leakage or contamination risk
- Systems with a defined torque-speed envelope and controlled air gap
- Chemical, pharmaceutical, food, semiconductor or medical equipment requiring clean interfaces
Check before release
- Rated torque must include startup, stall, viscosity, acceleration and transient loads
- The containment can introduces an air-gap and eddy-current trade-off at speed
- Over-temperature, overload or loss of synchronization can damage magnets or the can
- Hygiene, cleanability, pressure rating and material compatibility belong in the same review
ENGINEERING REVIEW
Review Torque Across the Isolation Gap.
Resolve the containment boundary, effective gap and full torque duty before selecting the coupling layout.
Torque and speed
Provide continuous, peak, startup and stall torque, speed range, acceleration, duty cycle and the driven fluid or load.
Process boundary
Define pressure, vacuum, leakage criterion, fluid chemistry, temperature, cleanability and the containment material requirement.
Envelope and interfaces
Share shaft, flange, bearing, can, air-gap and mounting dimensions, plus allowable misalignment and runout.
Failure modes
Describe dry run, blocked shaft, thermal runaway, loss of synchronization, reverse rotation and maintenance conditions.
QUALITY & RELEASE
Define Torque and Containment Checks.
Verification follows the component’s function and the agreed inspection plan.
Torque-speed curve
Review details
Test the coupling across the agreed speed and torque range, including startup, transient and thermal conditions.
Containment integrity
Review details
Use the specified leak, pressure, cleanliness or sterilization method on the final process boundary.
Temperature rise
Review details
Measure magnet, can, bearing and process-side temperatures under representative load and speed.
Runout and alignment
Review details
Verify concentricity, axial position, air gap and shaft alignment because mechanical error reduces torque margin.
PRODUCT QUESTIONS
Coupling Boundary and Duty Questions.
What is the main benefit of a magnetic coupling?
It transfers torque across a sealed boundary without a dynamic shaft penetration, which can reduce leakage paths and contamination risk when the complete system is designed and validated correctly.
How do I size a coupling?
Start with continuous and peak torque, speed, duty cycle, temperature, air gap, process pressure and fluid properties. Startup, stall and transient conditions are essential for selecting margin.
Can the containment can be non-metallic?
Material selection depends on pressure, stiffness, chemical compatibility, temperature, permeability, eddy-current loss and manufacturing method. The can should be reviewed as a system component, not chosen separately.
