Power characteristics of controlled five-phase low-power AC electronic motors

The influence of commutation control angle on the power characteristics of five-phase AC electronic motors with galvanically undone phases and five-phase ac electronic motors with armature coil open circuit powered from one source at full commutation is analyzed. During the adjustment of commutation control angle within one commutation interval at constant rotation frequency for each motor model the change of electromagnetic capacity and motors electromagnetic coefficient of efficiency is detected.
