Performance analysis of stator structure in divided teeth outer rotor embedded permanent magnet synchronous motor: salient pole stator vs segmented stator

To improve torque characteristics, this study proposes an upgrade over the standard salient pole stator in a Permanent Magnet Synchronous Motor (PMSM) using a segmented stator. The rotor is externally oriented and has a permanent magnet (PM) incorporated in it. The structure is studied theoretically...
