| Abstract: | armonic problems of large synchronous motor producetd by nolinear characteristic of cycloconverter are studied in this paper. The harmonic current,harmonic loss and torque ripple are emphasizedly analyzed, which come from stator magnetic force produced by harmonic voltage in stator windings on the constant speed steadystate condition. A rated 5 000 kW salient-pole synchronousmotor is taken as the example of calculation. |
