d-q-frame-currents. What and where are they in PMSM?
The Iq and Id currents for a PMSM are similar to Iq and Id for a salient-pole wound field synchronous machine (WFSM). Iq and Id are phasor components of the armature current. The Iq component is in phase with the generated armature voltage and produces a magnetic flux that is centered on the space between the permanent-magnet field poles. Id produces a magnetic flux that is centered on the permanent magnet poles.
