FAMAR required us an electromagnet fixed to the tip of a robotic arm, for the handling of raw and semi-finished cylinders of several sizes and weight (diameter from 60 to 400mm, weight from less than 1kg to 50kg).

The electromagnet had to have a high attraction force, in order to win even any air gap due to the presence of shavings on the piece to be handled.

It had, however, also to be extremely precise, to catch and release very small lightweight cylindrical workpieces. This kind of pieces, if moved by a standard electromagnet, once magnetized remain adherent to the polarity of the magnet: a simple counter-magnetization would not be enough to cause the detachment of the piece.

To meet the specific needs of FAMAR we designed a precise and reliable electromagnet, with a special feature: a special demagnetizing LRF (Low Residual Flux) control algorithm was developed within the PLC program of our electronic control equipment.

This special demagnetization curve, suitably set, minimizes the residual magnetism on the piece and allows the rapid and effective detachment also of the lightest pieces.
