| Abstract |
This paper deals with an improved model enabling
accurate simulation of inter-turn short circuits in the stator
windings of induction machines. This model is based on the
coupled magnetic circuits theory. The system of differential
equations describing the induction machine behavior in
presence of inter-turn short circuits in the stator windings is
given. The machine inductances expressions are carried out
using the airgap magnetic energy which is determined by means
of the winding functions method. In addition, the magnetic
circuit saturation is taken into account by including the
fundamental saturation harmonic in the inductances
calculation. The proposed model allows the authors to study
precisely the inter-turn short circuits signature. Finally, the
simulation results of the proposed model are validated by means
of a 4 kW specially rewound induction motor which is loaded by
a DC generator. |
