Advancement in power electronics over the last few decades has made it possible to utilize a variety of rotating electric machines that would otherwise not be feasible. One such class of machines is called reluctance machines because of the way they produce an electromagnetic torque. A reluctance machine is an electric machine in which torque is produced by the tendency of its movable part to move to a position where the inductance of the excited winding is maximized. A March 2020 Currents article discussed the switched reluctance motor (SRM) while this article will focus on the synchronous reluctance motor (SynRM). Let’s take a look at some of their similarities and differences.
