Abstract

Based on the main phase circuit parameters, extracted from magnetic field distribution (fluxes, energy), – Lm, Lsl, Lrl, Rs, Rr – the standard phase equivalent circuit of the induction machine (IM) with three phases is introduced and then, particularized for: ideal no-load speed (n0 = n1 = n; S0i = (n1 − n)/n1 = 0), no-load motoring (n = n0, S0 = (n1 − n0)/n1; S0>S0i), on load (S = (n1 − n)/n1>s0) but in the interval of 0.05–0.005, with increasing power, generator to the grid, capacitor (self-excited) autonomous generator, mechanical characteristic, efficiency, power factor, unbalanced stator or rotor operation, voltage sags, swells, and time harmonics, with numerical examples. Finally, the steady-state equivalent circuit of nested-cage dual-stator winding IM and cascaded dual-stator winding IM are presented in view of their recent proposition for wind energy conversion (new).
