Abstract

The scientific context in which the thesis project takes place, is that of electric machines. The work carried out is part of the realization of new configurations of asynchronous electric motors wound so as to allow the online change of the number of phases and poles generated. Such a type of motor is commonly referred to as WICSC (Wound Indipendently-Controlled Stator Coils). The main application to which we can refer for this type of engine is certainly the automotive field. The engine under study was designed to have a number of phases greater than or equal to three (commonly referred to as a multiphase machine).

The work presented in this thesis is based on the implementation on FPGA of two main structure preparatory to the realization of the complete control system of an induction machine with the capability of changing number of phases and poles
