Abstract
A control circuit for an electrically driven vehicle which employs a separately excited motor. The armature is connected in series with a current control between two supply rails. The field winding is likewise connected between the rails, but has associated with it switch means for reversing the connection of the field winding. A diode arrangement is provided for recirculating current when the field circuit is interrupted and for establishing a recirculating path through the vehicle battery when the field connections are reversed, by the switch means.
