Abstract :
This paper investigates influence of modified stator geometry on self-sensing capability of 3-phase TC-PMSMs. Asymmetrical geometry modifications compensate for local over-saturations under loading conditions and improve torque quality in TC-PMSMs. It is shown that self-sensing capability in the typical region of operation is also improved.
