Abstract
A new approach to investigation of two-phase PMSM control methods on the level of phase windings sections is presented. For two-phase PMSM with two-sectional windings all control methods are considered from a unified position. Section and phase usage variants implementable at all possible section connection schemes are determined and classified; armature magnetic induction vector amplitudes and angle positions are calculated. The vectors are grouped by graphical representation, phase usage variant and section connection scheme into sets, number of which leading to non-zero vectors and the zero vector is determined. A simulation is carried out, speed time response curves are calculated and compared; the affecting of section connection scheme and phase usage variant on speed transition time and idle speed is ascertained; groups are discovered, section connection schemes can be attributed to. The obtained results can be used in demand by drive developers to select the most suitable PMSM control method.
