FLUX CONCENTRATOR FOR ELECTROMAGNETIC PULLING

摘要

A flux concentrator has a pair of primary coils wrapped around a thin walled cylindrical portion of a secondary coil. The secondary coil has a conductive head at an end and the coil is slotted to generate a rapid high intensity axially acting flux at the head in response to a flow of current through the primary coils. A pulling force is generated as a result of a slow rise high amplitude current flow through one of the coils followed by a rapid rise reversed polarity current flow through the second primary coil.
