This work deals with the influence of magnetic saturation on machine parameters of a surface mounted permanent magnet synchronous machine driven by an ideal six-step three-phase inverter. In this third part, a special attention is given to each torque component on load condition, i.e., mutual torque, reluctance torque, cogging torque and a comparison between the electromagnetic torque and the summation...
This work deals with the influence of magnetic saturation on machine parameters of a surface mounted permanent magnet synchronous machine driven by an ideal six-step three-phase inverter. In this second part, a special attention is given to back-EMF calculation since the linkage flux of each phase has an abrupt change every sixty electrical degree due to the phase commutation.
This work deals with the influence of magnetic saturation on machine's parameters of a surface mounted permanent magnet synchronous machine driven by an ideal six-step three-phase inverter. In order to investigate and describe each machine's parameter, a review on Frozen Permeability Method is developed. Further, a general machine design characteristics are presented. At last, some simulation by means...
This work describes the design and optimization process of a direct-drive permanent magnet synchronous machine that is suitable for electric motorcycles. The machine is designed to develop approximately the same power than a conventional 250cc motorcycle internal combustion engine. The main goal of this work is to design an outer-rotor machine that is coupled directly to the wheel (direct-drive or...
This paper describes the development of an autonomous marine vehicle based on a trimaran structure, introducing the ship structure, the main control system and each of the subsystems onboard, including energy storage system, propulsion and sensors equipment. The main goal is to achieve high effectiveness to extend the mission capabilities of the vehicle through several techniques such as combining...
