In the period from 1.3.89 to 30.6.91, Saarbergwerke AG in collaboration with the firm of MMBT were to test in working conditions and evaluate economically the drive components protected against an explosive atmosphere, consisting of two permanent magnet motors and associated power electronics, as a double motor drive on a cable railway machine. An inherently safe control permitted for use underground was to be developed for initiating and monitoring the drive and its braking device, and to measure the operating conditions and monitor the railway track, and this was to be adapted for the 2 motor drive above ground. Finally, the drive and control units were to be tested and optimized in two years' use. The accompanying technical measurements of the experimental use by the DMT Company for Research and Testing GmbH were to supply the basis for assessing the alternative drive concept. (orig.)
