Starting prime movers, dynamo electric machines with control circuits for.-In an electric turning- gear, the battery is divided into two parts controlled by the double switch f, g. On the first movement of the switch, the field windings of the motor are separately excited to cause axial movement of the armature for coupling purpose. On further movement of the switch, the arm engages the contact g<2> whereupon the motcr acts as a series motor. Specification 23,357/14 is referred to.
