Abstract
569,004. Control of D.C. motors. TUSTIN, A., and METROPOLITANVICKERS ELECTRICAL CO., Ltd. May 31, 1941, No. 6986. [Class 38 (iii)] A motor 1 required to develop a constant torque, for example for driving a positive dis. placement pump of an oil servo system, is supplied from a constant voltage source 7 in series with the secondary brushes of a " Metadyne ". machine 4. The variator winding 9 is supplied with a constant current through a carbon pile regulator 10, and the motor Held 13 is either supplied from the same regulator or else it is in series with the motor armature. As shown the machine 4 is a generater driven by a motor 6. It may, however, be a " Metadyne " transformer with its primary brushes supplied from another source, or else constructed with two separate armature windings and commutators with the primary circuit supplied from the source 7.
