Electric drives : reliability of modular drive trains
Ghent University is a top 100 university worldwide and one of the major universities in Belgium, with more than 44,000 students and 15,000 staff members.
At the department of Electromechanical, Systems and Metal Engineering (ESME), the modeling and optimization of electromechanical drive trains is an important research topic.
The main research topic for this PhD study is modular drivetrains. A modular drive train consists of several identical modules.
A modular drive train can be either a motor that comprises modular windings each with its own converter, or a drivetrain that consists of several identical motors with synchronized speed.
Modular drive train topologies offer high reliability and flexibility in terms of power, speed, voltage, and current rating.
Reconfiguration of modules e.g. switching between series and parallel connection of motor winding modules or power electronic modules - allows to create drivetrains for different speeds, voltages, powers, always using the same modules.
The reconfiguration can also be done in real time to enhance the functionality of the motor. The modules themselves can be mass-produced, making them cheap and reliable.
The research challenge is to study modular topologies and exploit their benefits through reconfiguration, both in simulation and experiment, in the framework of an ongoing project.
Reliability of the modular drive trains is an important aspect of drivetrains that should also be studied in this project.
The reconfiguration options allow to switch off faulty modules and redistribute the load over the remaining modules. Lifetime prediction related to (cyclic) temperature profiles and / or peak voltages in the windings should be investigated.
The reliability study involves both modeling and experimental characterization. The reconfiguration makes this research about lifetime and reliability challenging, but also new compared to the state-of-the-art.
As a PhD student, you will work on several aspects of this project : brainstorming on new modular machine topologies, multiphysics and reliability modelling of some of these topologies, as well as designing and testing prototypes.
A strong interaction with other research partners in the project is required.
The initial contract duration will be one year, in which you are hired as a PhD researcher. The contract can be extended to a full 4-year PhD research period under the condition of a positive evaluation after the initial period.
Ghent University offers an attractive salary with additional benefits, a positive and inspiring working environment and training possibilities.
You will work at the Electrical Energy Laboratory in the Tech Lane Ghent Science Park in Zwijnaarde.
