This paper presents an investigation on the self-sensing capability of a dual three-phase synchronous reluctance motor. Self-sensing refers to ability motor properly operate in sensorless drive. The multiphase machine is decomposed into two different systems according multi-stator approach. Several supply scenarios are studied where windings controlled at operating points along reference trajec...

The spoke-type permanent magnet synchronous motor (PMSM), which is a general ferrite magnetic flux-concentrated motor, has low portion of reluctance torque at the total magnitude. Therefore, as way to increase torque, there double-layer PMSM that can maximize difference in inductance between d-axis and q-axis. However, PMSM, cogging ripple, harmonic distortion (THD) with main cause vibration no...
