PARAMETERS OF SOLID-ROTOR INDUCTION MACHINES WITH UNBALANCED SUPPLY

The tubular-axle induction motor (TAIM) with solid rotor when used with single-phase supply and a Ferraris-Arno phase conversion system for rail traction is considered. A mathematical model is presented for solid-rotor induction machines with unbalanced supply. Measurements are reported of the incremental permeability of steel under conditions where two alternating excitations of differing frequencies are superimposed. These data are used in a proposed method for calculating the negative-sequence impedance of the solid-rotor machine from design data. A new method is described for measuring the parameters of machines with unbalanced supply under actual operating conditions, and is shown to be useful when variations due to magnetic saturate are significant. The theoretical work is verified by tests on large and small machines (150 kw at 500 and 250 w at 1500 rpm). The application of the model in the simulation of traction systems is illustrated.
