Abstract

The aim of this paper is to investigate and compare the torque behavior of induction motors and transverse laminated synchronous reluctance motors. Each induction motor is compared with a synchronous reluctance motor, that has the same stator lamination and winding but, obviously, different rotor. The thermal analysis has been based on a fully experimental approach and the results have shown that the synchronous reluctance motor can give from 10% to 25% more torque than the corresponding induction motor, depending on motor size and importance of I.M. rotor losses. The torque comparison of the two motor types has been made at equal, measured winding temperature. In addition, the difference in power factor and efficiency is also pointed out.
