In the paper the no-load operations of PWM inverter fed induction motors are discussed and analyzed, with particular reference to the core and additional losses in presence of a distorted voltage supply. Starting from a previously developed method to predict the iron losses with PWM supply in magnetic laminations and special induction prototypes, the authors want to introduce the problems concerning...
The aim of this paper is to investigate and compare the performances of two induction motors and two transverse laminated synchronous reluctance motors (induction motor nameplate data: 2.2 and 4 kW, 380 V, 50 Hz, 4 pole). Each induction motor is compared with a synchronous reluctance motor, that has the same stator lamination and winding, but, obviously, different rotor. The analysis has been based...
