Abstract

504,536. Control of D.C. motors. RHEINMETALL-BORSIG AKT.-GES., and GIETMANN, A. Sept. 15, 1938, No. 26944. [Class 38 (iii)] Varying E.M.F.-In Ward-Leonard drive, particularly for gun-laying machines, in which the generator D is excited from an exciter C driven by means of a hand wheel B, the exciting circuit of the generator is broken when the generator is at rest by a centrifugal switch d<2> operated by the generator. Thus, if the wheel B is operated while the generator is at rest, no remanent magnetic field is created in the generator, and the driving motor A is not operated when the generator D is started.
