Productivity is a key competitive differentiator in many industrial manufacturing processes and a compromise between throughput and quality has to be reached. Many manufacturing processes rely heavily on complex electromechanical motion systems. The physical limitations of these systems have been reached and caused advances in productivity to have stalled in recent years. To still overcome these limitations a new research field is emerging in electromechanics that explores the application of coils comprising superconductive tapes to boost performance levels beyond the current state-of-art, i.e. cryomechatronics. Superconductive materials which allow coils to generate higher magnetic field strengths than currently achievable with permanent-magnet technology, result in a potential boost of force levels up to 3 times higher compared to permanent-magnet based technology. AC loss and quench phenomena in superconductive tapes however hamper the potential performance gain of motion systems. To fully unlock this potential a better understanding and description of the physical behavior of the superconductive coils in a physical environment that is representative of one found in motion systems is required. Within this research project it is the goal to broaden our understanding, characterization and modeling of the physical AC loss mechanism at the tape level for a wide variety of tape grades and coil configuration, such that at the design stage of the motion system reliable and accurate predictions of performance level indicators can be made. This research is conducted in close cooperation with our partner Twente University and is funded by the Materials Innovation Institute (M2I) in Delft, the Netherlands.
If you are interested in doing research in the emerging discipline of cryomechatronics, willing to apply and immerse yourself into a challenging multi-disciplinary topic to further push back the frontiers in motion systems, and you have an open attitude towards teamwork, you are invited to apply to strengthen our team.
As a PhD student you will be one of two main researchers in the project. The research will be jointly conducted in collaboration with Twente University. The research will be conducted within the Electromechanics & Power Electronics group of the department of Electrical Engineering. The research tasks include the characterization, modelling and localization of undesired parasitic phenomena that occur within high-temperature superconducting tapes (HTS) in stator-coils specifically intended for high-dynamic, translating actuators. The main focus is to map the AC loss distribution for different grades of tapes - both striated, nonstriated, insulated and/or non-insulated - as function of the HTS coil geometrical shape (e.g. bending radii) in conjunction the AC magnetic field originating from the translator to which the HTS coils will be exposed. The characterizations have to be performed under the conditions that are representative of those found in an actual actuator, i.e. AC fields rich in both time- and space harmonics. The research activities include the design of the experimental set-up and experimental verification.
