This paper studies the concerns such as architecture and reliability in the deployment of electromechanical actuator (EMA) in the actuation system for more electric aircraft (MEA). First, the reliability of the actuation system architecture such as c... Read More about Design Considerations of Fault-Tolerant Electromechanical Actuator Systems for More Electric Aircraft (MEA).

Consideration on Eddy Current Reduction Techniques for Solid Materials Used in Unconventional Magnetic Circuits (2018)
Journal Article
Mohammed, A. M., Galea, M., Cox, T., & Gerada, C. (2019). Consideration on Eddy Current Reduction Techniques for Solid Materials Used in Unconventional Magnetic Circuits. IEEE Transactions on Industrial Electronics, 66(6), 4870-4879. https://doi.org/10.1109/TIE.2018.2875641

The use of solid materials in tubular, linear machines has significant manufacturing benefits, as this removes the need for an axially laminated stator. However, this comes at the cost of extra eddy current losses. In this paper, a detailed analysis...

This paper proposes a new closed-loop control strategy which improves the quality of the torque output of an open-end winding (OEW) permanent magnet synchronous motor (PMSM) with common DC bus. Such a configuration provides a path for the zero sequen... Read More about Torque Quality Improvement of an Open-End Winding PMSM.

Mass Production Costing of Induction Machines for Automotive Applications (2018)
Presentation / Conference Contribution
Hundak, V., Cox, T., Vakil, G., & Gerada, C. (2018, June). Mass Production Costing of Induction Machines for Automotive Applications. Presented at 2018 IEEE Transportation and Electrification Conference and Expo (ITEC), Long Beach, CA, USA

Cost is one of the key parameters of electric machines designed for automotive applications. In order to keep manufacturing cost low, it is desirable to estimate the manufacturing cost of the machine in the early stages of the design process. For thi...
