Abstract

This paper presents a systematic scheme to determine the optimal torque trajectory of a single-sided permanent magnet axial-flux motor (SPMAM) along with its operational constraints on both the winding currents and the speed induced voltages. Appropriate projection of the stator currents to achieve an optimal ratio of the machine propulsive/axial forces has been confirmed through detailed numerical and analytical studies. From these evaluations, a feasible operational guidance for SPMAM field-oriented control scheme realizations can be suitably provided.
