MEASURING THE HYSTERESIS LOOPS OF TWISTED CORES

P. J. Kral

Abstract

A new type of SZ-stranding machines was developed at the Institute of Machine Elements and Machine Design. For the design of the stranding machine it was necessary to measure the occurring forces during the stranding process. Additionally it is from paramount importance to determine the required stranding torque.<BR />Therefore a test bed to simulate the stranding process for one insulated conductor was built up. This offers the possibility to record rotation angle and corresponding torque simultaneously during only one measurement procedure.<BR />Evaluation occurs computer-assisted, the hysteresis loops are created with the aid of spreadsheet routines. Interpretation of the hysteresis loops gives important hints for the design of the stranding head and the lay storage.
