pulse magnetisation
In order to perform their function, permanent magnets must be magnetised. The magnetisation of the state-of-the-art permanent magnets is almost exclusively performed by means of pulse magnetisation. Our laboratories are equipped with several pulse magnetisers, enabling two-pole pulse magnetisation. We perform pulse magnetisation of magnets as such as well as of magnetic circuits (e.g., two-pole rotors of electric motors and generators).
we perform the following types of magnetisation
- magnetisation of individual magnets (neodymium, samarium-cobalt, AlNiCo, ferrite)
- two-pole magnetisation of rotors and parts with magnets
Our pulse magnetisers are able to provide two-pole magnetisation up to the full saturation of all current types of magnetic materials and, if required, even to reverse their magnetisation direction, which is in particular suitable for segment-shaped magnets. The field intensities for magnetising a magnet from a thermally demagnetised condition are much lower than intensities required for a change in polarity (i.e., “remagnetisation”) of the magnet; however, our equipment can do that as well.
