Vector control versus brushless DC operation of a higher harmonic airgap wave based permanent magnet motor

The considered converter-fed permanent magnet motor could alternatively be operated in two basically different states - the vector control mode or alternatively the brushless dc also known as electronically commutated mode. Several quality aspects concerning the system performance have been comparatively investigated in practical as well as theoretical manner. Focus is thereby given to the numerical analysis and previous evaluation of the well interaction between the novel axially un-skewed higher harmonic airgap wave based permanent magnet motor design and both completely different control algorithms.
