Hollow Tube Electromagnets
- Best for "brute strength" applications requiring high power (20 kGauss and greater)
- Coaxial coolant path in direct contact with entire coil length
- Highest thermal conductance delivers maximum heat dissipation
- Extremely malleable into complex or unusual shapes
Liquid coolant flows through the entire coil length inside the hollow tube centers. This allows greater winding heat transfer than any other construction method, enabling the highest field strengths with extremely low temperature rise.
Non-conductive tubing (plastic shown) carries coolant without impacting the magnetic field pattern.
Stangenes' design routes cooling liquid in parallel, despite the necessary series path for coil current. Each coil set receives fresh incoming coolant at the same temperature.
Positive isolation of turns eliminates shorting, allowing low AC losses.
Extreme flexibility and malleability enables electromagnets of nearly any shape, including racetrack, thin pancake, open yoke and much more.
