Description
Summary:The multiphase machines present a lot of advantages when compared to the traditional three-phase machines, as example, for the same power, they operate with lower bus voltage and lower current per phase, present higher fault tolerance, and more specifically when it comes to concentrated windings machines, the harmonic current injection may be used to increase the torque production. Taking advantage of this last feature, in this work is developed the IFOC (indirect field oriented control) with current harmonic injection for a concentrated windings nine-phase induction motor drive, what confers the variable-speed machine operation with flux waveform optimization, reducing its peak value, giving better use to the iron core and allowing power density improvement.
