Abstract

1353490 Control of D.C. motors TOYO KOGYO CO Ltd 30 July 1971 36002/71 Heading H2J The control system of an electric vehicle having a D.C. motor with armature 1 and field winding 1a and batteries 2-5 interconnected by diodes 9-14, comprises a circuit breaker 17 which is respectively closed and opened during the driving and decelerating conditions of the vehicle, a changeover switch whose movable contact 20 respectively engages fixed contacts 20a and 20b during the driving and decelerating conditions, a braking resistor 21, a starting resistor 18 controlled by a switch 19 and switches 6, 7, 8 controlling the batteries 2-5. In the driving condition, five speeds are obtained by starting with all the switches 6, 7, 8, 19 open, Fig. 2a (not shown), and then successively closing them in a predetermined sequence, Figs. 2b-2e (not shown), whereby the voltage applied to the motor is increased in steps. Further speed control may be obtained by altering the ratio of a change speed gear of the vehicle. In the decelerating condition, all the switches 6, 7, 8, 19 are opened and the motor is braked by a combined regenerative and dynamic effect, the former occurring when the motor generated EMF exceeds the voltage of the batteries which are charged through the diode 15 and which produce a constant voltage across circuit members 1a, 18, so that the motor operates as an externally excited shunt generator, Fig. 4 (not shown). When the motor speed falls below a certain value corresponding to a generated EMF below the battery voltage, the braking becomes entirely dynamic through circuit members 18, 21, 1a and the diode 16 which has hitherto carried the combined regenerative and dynamic braking current. The motor then functions as a series generator. Typical speed/ current characteristics are discussed, Fig. 5 (not shown), to explain the braking operation. Further characteristics relating vehicle speed to braking force during the regenerative braking action, Fig. 6 (not shown), are discussed to explain how the ratio of the change speed gear is altered at progressively lower vehicle speeds to vary the braking current between an upper and a lower limit. Switches 6, 7, 8 and diodes 10, 12, 14 may be replaced by three changeover switches connected between the batteries 2-5, Fig. 8 (not shown).
