In the context of the non-conservative system, in 2006, Gao Deli [5] obtained expressions for the sinusoidal and helical bucking force when the axial and tangential friction was considered.
In the sinusoidal mode of the three-phase voltage source, the active current vector also consists of sinusoidal temporal functions, so it is expedient [5] to introduce three-dimensional complex vectors (3Dphasors) of voltage and current in the same way [5].
Nevertheless, due to the fact that the classical apparent power and its resolution are defined under sinusoidal and balanced conditions, they did not attain their goals in the case of nonsinusoidal and/or unbalanced conditions.
