Performance evaluation of a new modular split‐tooth permanent magnet‐assisted switched reluctance motor

open access: yesIET Electric Power Applications, 2023
This study elaborates upon a new modular split‐tooth permanent magnet‐assisted switched reluctance motor (MSTPM‐SRM). In the proposed topology, the stator comprises six modular E‐cores in which the middle poles are split into two teeth.
