Abstract
350,256. Master control of D.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.- (Cutler-Hammer Manufacturing Co. ; Milwaukee, Wisconsin, U.S.A.) June 23, 1930, No. 19117. [Class 38 (iii).] Field control; armature control.-A motor is accelerated by repeatedly including and excluding a resistance in the armature or field circuit by means of a vibrating relay actuated by induced current according to the variations of the motor current. In Fig. 1, switches 1, 2, 3 are closed successively by the movement of a master switch 4 to its third position. Upon movement to its final position the switch 4 energizes an opening coil 25 of a vibrating relay 5, a closing coil 24 of which is repeatedly energized by currents induced through a transformer T by the surges of motor current. The relay 5 is thus vibrated to include and exclude a resistance r2 in the field circuit. When the motor reaches full speed the final surge is insufficient to energize the coil 24 and the relay 5 remains open. In Fig. 2 (not shown) the vibrating relay controls a resistance in the motor armature circuit.
