Abstract
A transporter suitable for conveying ferro-magnetic materials [3] out of progressive-line transfer dies during stamping and other similar processes. This device does not utilize an inline synchronous or induction motor. In order to move the ferro-magnetic material out of said dies, the transporting system has coils wrapped around the core [1] (primary) insulated in their slots, said coils wrapped in a plane located at 90 degrees to the transfer plane so as to maintain one polarity along the transfer direction at any given time. To achieve continuous movement of the ferro-magnetic material [3] in the plane of transport, the current applied to the system is sequentially switched from coil [2] to coil using a mini programmable logic controller, or similar device. As this current is switched, the ferro-magnetic material behaves as a secondary, therefore applying motive force on the material in the transfer plane.
