Abstract: A driving system adapted for regenerative braking having two DC motors each having two series wound field windings. The motors and one field winding from each motor are connected in a bridge circuit to a DC source to provide for changing from motor to generator conditions. the other two field windings are connected in series with each other and with the DC source in a diagonal of the bridge. The motors are controlled in response to the average value of motor current.
