Field oriented control of this machines, migrated from their rotary counterparts, has been considered as a superior control strategy. This paper reports on secondary effects such as trailing eddy currents, non-sinusoidal magneto-motive force (MMF) in the airgap, and asymmetrical end effects which can significantly undermine the functionality of a direct or indirect field oriented control in this family of machines.
