apposing flow of current is the armature circuit resistance, which is quite small for all types of DC motor.[01] If a DC motor is started with full supply voltage across its terminal, a very high current will flow, which may damage motor due to heavy sparking at commutator and heating of winding. Therefore it is necessary to limit the current to a safe value during starting. When motor speed 1 MEDIUM VOLTAGE REDUCED VOLTAGE AUTOTRANSFORMER STARTER FAILURES – EXPLAINING THE UNEXPLAINED – Lawrence B. Farr Sr. Member, IEEE Principal R & D Engineer

The solution to this question may be easier for some to recognize if the regulator circuit is re-drawn using normal electronic schematic diagrams. Another tip is to simplify the schematic diagram by removing all the different tap positions, and draw the circuit using the full series winding. A ∆ – ∆ autotransformer connection is theoretically possible; however, this will create a peculiar phase shift. The phase shift is a function of the ratio of the primary to secondary voltages and it can be calculated from the vector diagram.
