Modélisation des machines asynchrones et synchrones a aimants avec prise en compte des harmoniques d'espace et de temps : application à la propulsion marine par POD

Abstract : This work concerns the modeling and the design of the permanent magnets and
asynchronous motors intended for POD ship propulsion. A state of the art is presented, where
various topologies of motors designed for this application are approached there. The permanent
magnet motor and the induction motor have been chosen for the application.
For the permanent magnets motor, a finite element analysis is adopted to design and
minimize the main harmonics leading to a quasi sinusoidal back EMF. A finite element model
coupled to an electrical circuit allows to predict both current and torque waveforms including
time harmonics knowing the voltage waveform of the inverter.
The induction motor is designed in such a way to have minimum losses and pulsating
torque. For this purpose, a 2D complex finite element method coupled to an electrical circuit is
developed. In addition, another 2D finite element-electrical circuit model is proposed to evaluate
time harmonics losses and to reconstitute the current and torque waveforms. This model allows
to predict the pulsating torques.
The validation and verification step is done by using a time stepping finite element
software Flux2D and some available measurements (for the permanent magnets motor). The
comparison of the calculations obtained by the different methods and software, as well as the
available measurements is satisfactory.
