A New 3-D Flux Transverse Flux-Switch Reluctance Motor

Using Switched Reluctance Motors (SRMs), due to their benefits like high torque output, robust design, high reliability, easy manufacturing, and higher energy efficiency compared to the inductance motors, has become spread in many industrial and commercial applications. Despite the advantages of SRMs, the most important drawback of these motors is severe torque ripple which causes noise and trembling. Air gap reduction makes the flux linkage increases and thereby the torque increases proportionately. However, the smaller the air gap surface, the larger pull, and torque ripple. The driver control torque reduction strategies are independent of the design of the motor and could be used in all types of SR motors. Design optimization methods, which are other methods to compensate SRMs drawbacks, deal with the design of geometrical and electrical parameters. Although these researches, the necessity of significant torque ripple reduction still required to make SRMs more industrial. Presentation of a new structure of reluctance motor which strongly reduces torque ripple has been hence set as the main objective of this study. Although this newly proposed topology greatly reduces the torque ripple, the point is all previous methods like drive control and design optimization, could be used to reduce more torque ripple. This new topology of SRM has some significant benefits like manufacturing cost reduction, easy assembly, and high winding slot fill-factor. Due to the special flux path in this topology, SMC material should be used in this motor.
