Ryan has a Master's degree in Mechatronics from the University of Bath, which he completed after studying a Bachelor's in Renewable Energy Engineering at the University of Exeter. Ryan is interested in applying his knowledge of mechanical and electrical engineering to the electrification of automotive propulsion. During his Master's he lead the powertrain team for the University of Bath's autonomous electric formula student car and subsequently completed his thesis on the thermal management of a solid polymer electrolyte lithium metal battery pack. Within the AAPS CDT Ryan aims to widen his knowledge of other disciplines relating to the sector and develop electrical powertrain technologies, with a focus on battery systems. Outside of University he likes to run, cycle, and work on motorcycle projects!

Robust Real-Time Thermal Modelling of High-Speed Permanent Magnet Synchronous Machine

Ryan's PhD will develop a reduced order thermal model of a high-speed permanent magnet machine, forming a key part of a future digital twin. The model will allow for a variety of cooling methods such as air, water, and oil to be simulated. The proposed model will enable predictive and real-time estimation of the electric machine’s thermal behavior. Specifically, enabling the temperatures of physically difficult to measure components to be found, such as the rotor or magnets. By better understanding the temperature of key components within the machine in real-time and into the future the machine can be overloaded more often without damage. This will improve the power density of the machines and enable special test cycles to be performed that may otherwise have been thought to cause overheating.
