Zero-Seqence Component in Three-Phase Inductions Motors

Result description

The paper deals with such a case of influence of zero-sequence component on the induction machine when this component arises due to connection of the stator winding neutral with the feeding source. The relationship between the zero-sequence component andthe third space harmonic of stator current layer is shower. Furthermore, the paper deals with the methods of suppressing the undesirable influence of the zero-sequence component on the induction motor, especially an increase of additional losses and a rise of parasitic torques.

    Nulová složka v třífázových asynchronních motorech

  • Czech description

    Článek se zabývá vlivem nulové složky v indukčním stroji v případě, že tato složka vzniká při propojení uzlu statorového vinutí s napájecím zdrojem. Je ukázána souvislost nulové složky se třetí prostorovou harmonickou proudové vrstvy statoru, magnetickéindukce ve vzduchové mezeře a toku ve jhu. Pozornost je věnována rovněž možnostem potlačení nežádoucích účiníků nulové složky, jako je zvětšení přídavných ztrát a vznik parazitních momentů.
