Sigmaphi team has been here to design, manufacture, measure and install the magnets you need :
• Dipoles, multipoles, solenoids
• DC, AC, scanning magnets
• From 20kg to more than 100 tons
• With solid steel yoke or laminated steel yoke (1mm, 0.5mm, 0.35mm…)
• With plain enameled or hollow copper conductor (including oversized cross sections)
• Extreme environments resistants (heat, vacuum, radiations…)
Our expertise in magnetic design and magnetic measurement is the guarantee that magnets will be optimized for your application.
Our magnets are delivered turnkey, when required: including vacuum chamber, adjustable support stand and feet, and suitable power supply.
Through its experience on resistive magnets and its industrial capacities, Sigmaphi can manufacture medium-sized series in record time and has a sufficiently flexible organization to answer any of your needs. Increasing manufacturing capacities or manufacturing an over-sized product? Our team is ready to accept the challenge.
Every year, we manufacture more than 1000 magnets, some which weigh more than 100 tons.
