Historically, reluctance motors were frequently used in large numbers connectedinparalleltolarge ‘bulk’ power electronic inverters. The fact that the motors were locked in synchronism was a great advantage over the induction motor for synchronized/coordinated applications, notably in the textile industry. However, the falling cost of power electronics and advances in control saw such applications being addressed by means of individual inverters with dedicated induction motors and overarching control. Recently,however,some drives companies are once again promoting reluctance motor drives utilizing off-the-shelf converter and control hardware, perhaps stretched to the limit, to obtain performance comparable to that of an induction motor.
