The thesis deals with the improvement of electric motor simulation for control calibration under healthy and faulty conditions, including the effects of PWM voltage and electric motor harmonics fields. The design study of an electric motor (eMotor) starts with the electromagnetic design, using Finite Element Analysis for the evaluation of the motor output figures and parameters. This is the original purpose of the SyR-e (Synchronous Reluctance-evolution) open source design environment. More recently, the SyreDrive add-on was introduced, whose purpose is to generate a Simulink model for control calibration and accurate waveform simulation, starting from the eMotor design results. Therefore, the thesis aims at developing a unified circuital Simulink and PLECS model for eDrive (e-motor + inverter +control) suitable for both Permanent Magnet Synchronous Machine (PMSM) and Synchronous Reluctance (SyR) machines.
