The application of vector control to a conventional synchronous reluctance motor (VCSynRM) is presented with emphasis on the effects of saturation and iron losses. It is shown experimentally that these parasitic effects can significantly influence the performance of a VCSynRM. A simplified d-q model that includes saturation and iron losses is presented, and(More)
An alternative topology for a synchronous reluctance motor (SRM) is proposed utilizing a novel five-phase, concentrated winding, wye connected stator. The corresponding inverter requires only 10 transistors, each of which operates at a better switch utilization factor than a conventional three-phase, six-transistor bridge. Linear analysis is used to search(More)
A novel type of two-phase synchronous reluctance motor drive is introduced and analyzed. Since the currents in the phases are undirectional rather than bidirectional, the associated power converter requires only two transistors and two feedback diodes. It is demonstrated by finite-element analysis that with the same amount of active copper and under the(More)
Optical polarization provides important clues to the magnetic field in blazar jets. It is easy to find noteworthy patterns in the time-series data of the polarization degree (PD) and position angle (PA). On the other hand, we need to see the trajectory of the object in the Stokes QU plane when the object has multiple polarized components. In this case,(More)
