Vliv nulové složky statorových proudů na magnetické pole a přídavné ztráty asynchronního motoru v nouzovém chodu
Schreier, Luděk ; Bendl, Jiří ; Chomát, Miroslav
Two-phase feeding of induction motors under emergency operation from a voltage-type converter controlled so that currents of connected stator phases can have the required amplitude and phase shift is analysed. Based on the analysis the amplitudes and the phase shift of the fundamental time harmonic of the converter output currents are determined so that at required torque the machine can operate with minimum stray losses.
