Chen Chen successfully defended his PhD thesis entitled Variable Flux Permanent Magnet Machines for Sustainable Traction Electrification in front of the PhD Committee: Prof. Daniel Fernández, Dr. Alessandro Acquaviva, and Prof. Luca Ferraris. The PhD supervisors are Gianmario Pellegrino and Paolo Pescetto, and the research was funded by Volvo Cars. The PhD dissertation covers: •⁠ ⁠Rotor geometry selection for Variable Flux Machines (VFMs) equipped only with rare-earth-free Low-Coercivity-Force magnets, aiming to minimize remagnetization current requirements and ensure torque controllability during Magnetization State (MS) variation transients. •⁠ ⁠⁠Development of a computationally efficient VFM electromagnetic model capable of representing irreversible and asymmetric magnetization phenomena under load. •⁠ ⁠⁠implementation of the VFM control model in a real-time Hardware-in-the-Loop environment, enabling long-duration and vehicle system-level simulations. •⁠ ⁠⁠Development of two dedicated control strategies to mitigate torque perturbations during MS variation transients, one based on Direct Flux Vector Control and one based on Field-Oriented Control. This work resulted in a joint patent between Volvo Cars and Politecnico di Torino. •⁠ ⁠⁠Definition of a method for determining the remagnetization limit and feasible torque-speed operating region under inverter voltage constraints. Congratulations to Chen on this important achievement in his career! #SustainableTransportation #RareEarthFree #VariableFluxMachine #IrreversibleDemagnetization #ElectromagneticModeling #ElectricDriveControl

Gianmario Pellegrino receives the ICEM 2026 Michel Poloujadoff Award   Professor Gianmario Pellegrino has been awarded the #ICEM #2026 Michel Poloujadoff Special Recognition Award. The award was presented in recognition of his outstanding #contributions to the #electrical #machines and #drives community and to the continued success of the International Conference on Electrical Machines (ICEM). Over more than a decade, Professor Pellegrino has contributed actively to ICEM. He received the ICEM Brian Chalmers Best Paper Award twice, and delivered tutorials at ICEM in 2016, 2022, and 2026. He also served as Track Chair on several occasions and chaired ICEM 2024, which was hosted in Turin by Politecnico di Torino. This recognition is particularly meaningful for the Politecnico di Torino electrical-machines community and reflects Professor Pellegrino’s longstanding commitment to advancing research, education, and international collaboration in electrical machines, power electronics, and electric-drive systems. The award is named in honour of Professor Michel Poloujadoff, co-founder of ICEM in 1974, whose scientific work and service have had a lasting impact on the international electrical-machines community.

Last Sunday at ICEM26, Gianmario Pellegrino and I, from Power Electronics Innovation Center of Politecnico di Torino, presented the tutorial "Hands-on Design and Optimization of IPM Traction Motors with SyR-e". During the tutorial, we showcased how to use SyR-e to sketch a preliminary design of a traction electric motor, run simple FEA simulations with SyR-e and perform advanced analysis, included evaluate the PWM effect on PM loss. This was the first hands-on tutorial we prepared on SyR-e, laying the groundwork for our next hands-on tutorial on eDrive simulation which will be presented at the upcoming ECCE (https://lnkd.in/e-7s4X-7). A special thanks goes to Paolo Panarese Ph. D. and Carlos Sanchis from MathWorks for helping us providing temporary licences for the attendees and Jennifer J. Gago Muñoz for her precious support during the tutorial. A special mention also goes to Ruggero Seccia, Luca Zai and the entire MoBeLIV team for giving us access to their M4V-Flow software, enabling SyR-e to run fast transient thermal simulations.
