Pot magnets & electromagnets

Pot magnets and round electromagnets


Goudsmit supplies pot magnets and round electromagnets of high quality. Compact magnetic systems with a shell of steel, brass, high-grade steel or plastic. Depending on the shell of these magnetic systems, the magnetic field strength increases and/or the pot magnets are more resistant to corrosion or chemicals. Pot magnets have just one attraction plane; this allows the magnetic field to propagate in one direction only.


Pot magnet materials


Pot magnets are available in the following materials:

Neodymium (NdFeB)

Samarium Cobalt (SmCo)

AlNiCo

Ferrite (FeB)


The maximum application temperature ranges from 60 to 450 °C.

We also have electromagnets in the product mix.


Installation options


Pot magnets and electromagnets are available in various designs: flat, threaded bush, threaded end, countersunk hole, through hole and threaded hole. The many different models mean there is always a suitable magnet for your application. Goudsmit is happy to provide installation recommendations or help you choose the right pot magnet.


Conditions for optimum magnetic holding force


For optimum holding force the pole faces of the pot magnet should be clean and the work pieces flat. The specified holding forces are measured under optimum conditions: perpendicular, on a piece of grade 37 steel that has been ground flat to a thickness of 5 mm, without air gap. Small cracks in magnetic material have no effect on the pull force.

In principle, pot magnets retain their magnetic strength indefinitely if not exposed to these four factors (see 'Does a magnet lose strength over time?')

Products

Neodymium (NdFeB) pot magnets

Neodymium pot magnets are the strongest pot magnets in our range. Corrosion protection of the product is ensured by a coating of nickel, zinc or santoprene.

Ferrite pot magnets

Ferrite or ceramic pot magnets are fitted with a steel pot that provides shielding from the magnetic field. The minimal installation height offers many constructive advantages.

More information

Samarium-Cobalt (SmCo) pot magnets

Samarium-cobalt (SmCo) pot magnets offer the unique combination of high magnetic force and high operating temperature.

More information

AlNiCo pot magnets

AlNiCo pot magnets have a very high application temperature. The housing is steel, with a non-magnetizable material in between.

Electromagnets

Round electromagnets are switchable. They serve for picking up, positioning or holding products.
