Abstract
The paper presents a FEM-based analysis of output power capability (OPC) improvement in a six-phase flux-weakened permanent magnet synchronous motor with a third 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 influence of the iron losses on the OPC and the constant-power speed range (CPSR) is included in the analysis by the posterior iron loss calculation. The improvement of the machine OPC with a third harmonic current injection depends on the level of flux-weakening and it is higher at a high level of flux-weakening. The Results of the analysis are partially verified with the measurements.
