Electrical maps of induction machines

The study of circular maps of induction machines is one of the classical subjects dealt with in literature about electrical machines and it is fairly interesting from a didactical point of view as well as from its practical applications. This paper presents a new and general method that allows for, among other things, the analytical way of obtaining center coordinates and the radius of any of the geometrical maps (impedance, admittance, current, voltage, and power) of induction machines. To reach this goal, a two-port model associated to any of the equivalent induction machines is used
