I. Introduction
The line-start synchronous reluctance (LSSR) machines are more and more used in several applications replacing induction machines (IM). The main reason is that their efficiency results to be higher than the IM, since there are no rotor current at steady state. Since there is no permanent magnets (PMs) included in the rotor, the LSSR cost is lower than PM machines. In addition, the rotor cage allows the machine to start up directly with line voltage, without inverter.
