An enhancement of output torque ripple of the switching reluctance motor based on appropriate time switching selection

Abstract

The Switching Reluctance Motors (SRM for brief) have attracted a host of interests of scientists in recent years because of their outstanding advantages such as low manufacturing costs, simple configuration, high durability and an ability to operate at high speeds. In addition to their benefits, some disadvantages causing the SRMs’ performance can be listed as high torque ripple, excessive acoustic disturbances,and difficulties in controlling. They are serving as our motivation to perform studies aiming to enhance SRM’s operational quality. The SRM’s performance depends upon torque characteristics and rotational speed features. To better torque characteristics, an appropriate time-switchingselection is proposed. Because moment features are always the decisive factor for motors’ effectiveness in general and it is more vital for SRM owing to the high torque ripple stemming from the switching process. This is the compelling reason why the selecting appropriate switching time among phases of SRM is particularly important. This paper proposes a method for determining this time based on the numerical simulation. Results are warranted thoughtfully consideration and they are the precise of systhesising a fuzzy logic system being able to automatically choose the switching time
