Abstract

A control circuit which eliminates the need for wiping contacts normally employed in conjunction with traction motors for use in operating vehicles. Forward or reverse operation of the traction motor (and hence the vehicle) is controlled by a plunger movable with the vehicle foot pedal. An oscillating circuit develops an output whose rate controls the speed of the traction motor. The output rate of the circuit, in turn, is controlled by any circuit having a storage member which alternatively either charges or discharges according to its electrical connection so as to cause the oscillating circuit to reach the final selected frequency in a gradual manner. A braking circuit is also provided for gradually braking the traction motor.
