What is the first step in the design of the field regulators for dc machines?
(a) calculation of the resistance of section
(b) calculation of the total field circuit resistance
(c) calculation of the field circuit resistance
(d) resistance to be inserted
This question was posed to me in examination.
My question comes from Motor Starters, Calculation of Resistance Steps & Design of Field Regulators topic in chapter Design of Small Electrical Machines, Starters and Field Regulators of Design of Electrical Machines
