Abstract :
This paper presents a FEM based analysis of output power capability improvement (OPC) in a six-phase flux-weakened permanent magnet synchronous motor with a harmonic current injection. It is shown that the flux-weakened permanent magnet synchronous motor with the third harmonic current injection is capable of producing more output torque per RMS current flowing through the windings than the same motor supplied with sinusoidal currents. The results of the analysis are partially verified with the measurements.
