Abstract: 635,062. Control of D.C. motors. PESTARINI, G. M. Sept. 26, 1946, No. 28749. [Class 38 (iii)] In a traction system with motors or sets of motors across alternate pairs of brushes of a metadyne having a fly-wheel on its shaft to permit its operation as a generator when the motors are heavily loaded, the pairs of brushes not so connected to the motors are connected in closed circuits when the metadyne is disconnected from the supply during braking or other conditions. As shown, the metadyne field windings Wl, W2 are fed by separate exciters each having five field coils including one supplied from the regulating dynamo RD opposed by the constant voltage of BD and short-circuited during braking. The fields Fl, F2 of the motors M1, M2 are fed by other exciters having separate excitation, also field coils connected across the respective interpole windings IM1, IM2 of the motors. The first stage in bringing the vehicle to rest is to open line switch Cl and close contactors C3, C6, thereby directly short-circuiting brushes a, d and b, c, also field winding 46 of motor AM adjusting rheostat RR in the circuit of regulating dynamo RD is opened so that this motor then acts under control of windings 43 (separately excited) and 69 to govern the flywheel retardation and keep the motor current constant. The motor AM is connected to a reversing switch for motoring or braking conditions of the main motors. Resistances 2, 3 can then be introduced to obtain further braking and/or resistance BR can be connected across brushes b, d. In starting up the metadyne and fly-wheel are brought up to the required speed before the motor fields are energized. Specifications 635,059, 635,060 and 635,061, [all in Group XXXV], are referred to.
