Title:
INDUCTION DRIVE FOR INDUCTION DRIVEN CONVEYOR
Document Type and Number:
WIPO Patent Application WO2003031288
Kind Code:
A3
Abstract:
Induction drives for either straight or curved conveyors as well as methods of driving endless conveyor belts. Pivotable magnets (310...) can be free floating in holders (330), or in other embodiments, each pivotable magnet (50...,190...,350...) can be interconnected serially with its previous and its subsequent magnet. Whether free floating or serially interconnected pivotable magnets (50...,190...,310...,350...) create the virtual continuous magnetic body (150...,290...,440...). When the virtual continuous magnetic body (150...,290...,440...) encounters the stator's electromagnetic field the resultant magnetic flux pushes the continuous magnetic body (150...,290...,440...) through the groove (40, 210, 230) of the conveyor bed (38, 112, 220). Each of the pivotable magnets (50...,190...,310...,350...) is dimensioned to not impede its previous magnet and its subsequent magnet, when the electromagnetic flux is reversed.
