Textile machine energy and signal transmission

摘要

The transformer has only one pair of coils for a common carrier signal to take the energy and signals. The carrier signal itself, is the energy carrier, and the carried signals are formed by frequency modulation imposed on the carrier. The carrier signal jumps between two frequency values, at a set gap apart, and frequency jumps are evaluated as bit-serial signals on a secondary side, to generate the control signals. Also claimed is an appts. where the two cores (6.12,6.22) of the transformer are structured for their opposing sides to match the contour and especially the curvature radius of the air gap (9), and particularly at the opposing end surfaces of their legs. The gap between the two legs of each core (6.12,6.22) is larger than the width of the air gap (9) by a multiple of it.
