| titleOfInvention | Servocontrol with time delay and ramp motor start |
| abstract | Motor control circuitry imparting time delay and ramp start characteristics to the bidirectional operation of a servomotor. Ramp start is determined by a constant current generated in a transistor circuit charging a capacitor. A further transistor in a circuit responsive to development of the ramp voltage sensed at its base-emitter junction directs growth of a motor voltage control signal to follow ramp form towards a maximum value. A motor energizing voltage feedback received in the emittercollector circuit of the further transistor opposes the baseemitter junction voltage and effects a dampening of the motor control voltage buildup until consequent lessening of the motor control voltage lessens motor energizing voltage with the result that the further transistor acts to further develop the motor control voltage whereby the effect of the feedback loop thus made operative is progressively diminished as motor energizing voltage is permitted to follow a ramp form to its normal operational value. |
