Abstract
1377502 Control of D.C. motors CABLEFORM Ltd 12 Jan 1972 [20 Jan 1971] 2812/71 Heading H2J A control system for the motor of a battery operated vehicle comprises a D.C. switch S for controlling the supply of current from the battery B to the electric motor A, F, a by-pass contactor CT2 having contacts ct2 which, when closed, shunt switch S, a microswitch MS2 operable by a speed controller in its maximum speed demand (40) condition and included in an enabling circuit of the by-pass contactor CT2 and time delay means for delaying the energization of contactor CT2 as a function of the motor current. Voltage developed across a resistor R10 controls the current through a transistor T5 included in the charging circuit of a capacitor C1. Capacitor C1 remains clamped by a transistor T 1 until predetermined control contacts MS 1, rlb1, rlc1, are closed and the speed controller is in its maximum demand position (switch F/R S being operated appropriately to select forward or reverse). The bistable switching circuit T2, T3, D1, R2, changes state when the voltage of capacitor C1 reaches a predetermined level and thereby causes energization of a relay RLA having contacts rla1 included in the energization circuit of the by-pass contactor CT2. Voltage VI from resistor R10 is compared with reference voltage VR and amplifier AMP with feed-back H provides an output signal combined in a unit E with the demand signal VD from the speed control pedal to provide a modified control signal to switch S. The amplifier output signal is also connected to one end of a potentiometer supplying the base of a transistor T5 with collector load R1 and C1, such that the signal controls the charging of C1 in a time inversely proportional to the motor current. A transistor T4 switches off switch S prior to operation of by-pass contactor CT2 and ensures that it remains off until CT2 is opened.
