Abstract

Anisotropy-based initial rotor polarity detection of interior
permanent-magnet synchronous machines (IPMSM) relies typically on the
saturation in the stator iron. The current response to a voltage pulse
into the north pole (d+) direction of the magnet should be
higher in magnitude than into the opposite direction because of
increased stator saturation. However, experiments show sometimes an
opposite result. The present paper considers the bridge-saturation in
the rotor to explain this phenomenon. Finite element (FE) analyses of
six modified PMSM models demonstrate that the bridge-saturation
decreases, as the flux linkage begins to increase. That leads to an
increase of the differential inductance if the stator iron is not
strongly saturated. The impact of the machine geometry parameters on the
differential inductance is also studied in this paper by means of a
sensitivity analysis.
