A conveyor transfer apparatus in the form of a transfer platform configured to be located in a gap between an infeed conveyor and a discharge conveyor, over which articles travel between the end-to-end conveyors (36,38), the conveyor transfer apparatus characterised in that it comprises: an array of electrically conductive rollers rotatable on axes perpendicular to a conveying direction; a stator disposed below the array of electrically conductive rollers and including a magnetic core having: a short side; a long side parallel to the short side, wherein the long side is nearer the array of electrically conductive rollers than the short side and extends in a conveying direction from a first end to a second end; a plurality of slots (56, 57) spaced apart in the conveying direction and extending in depth from the long side toward the short side and in length transverse to the conveying direction to form poles with pole faces on the long side between consecutive slots and first and second end faces on the long side at the first and second ends; windings in the slots (56, 57) and around the poles to generate a magnetic flux wave traveling along the conveying direction to induce eddy currents in the array of electrically conductive rollers and cause the electrically conductive rollers to rotate in the conveying direction. an array of electrically conductive rollers rotatable on axes perpendicular to a conveying direction; a stator disposed below the array of electrically conductive rollers and including a magnetic core having: a short side; a long side parallel to the short side, wherein the long side is nearer the array of electrically conductive rollers than the short side and extends in a conveying direction from a first end to a second end; a plurality of slots (56, 57) spaced apart in the conveying direction and extending in depth from the long side toward the short side and in length transverse to the conveying direction to form poles with pole faces on the long side between consecutive slots and first and second end faces on the long side at the first and second ends; windings in the slots (56, 57) and around the poles to generate a magnetic flux wave traveling along the conveying direction to induce eddy currents in the array of electrically conductive rollers and cause the electrically conductive rollers to rotate in the conveying direction. a short side; a long side parallel to the short side, wherein the long side is nearer the array of electrically conductive rollers than the short side and extends in a conveying direction from a first end to a second end; a plurality of slots (56, 57) spaced apart in the conveying direction and extending in depth from the long side toward the short side and in length transverse to the conveying direction to form poles with pole faces on the long side between consecutive slots and first and second end faces on the long side at the first and second ends; windings in the slots (56, 57) and around the poles to generate a magnetic flux wave traveling along the conveying direction to induce eddy currents in the array of electrically conductive rollers and cause the electrically conductive rollers to rotate in the conveying direction.
