Electromagnetic and Thermal Evaluation of Surface-Mounted PM Vernier Machines (2021)
Presentation / Conference Contribution
Ahmadi Darmani, M., Vaschetto, S., Cavagnino, A., & Popescu, M. (2021, October). Electromagnetic and Thermal Evaluation of Surface-Mounted PM Vernier Machines. Presented at 13th Annual IEEE Energy Conversion Congress & Exposition (ECCE 2021), Vancouver, BC, Canada (online)

This study investigates the electromagnetic and thermal performance of surface-mounted permanent magnet vernier machines. In particular, different losses and thermal behaviour of PM vernier machines are evaluated considering different gear ratios and...

Noninvasive Measurements and FEM Analyses for Estimating the Rotor Bar-Lamination Contact Resistance (2021)
Journal Article
Gmyrek, Z., Vaschetto, S., Ahmadi Darmani, M., & Cavagnino, A. (2021). Noninvasive Measurements and FEM Analyses for Estimating the Rotor Bar-Lamination Contact Resistance. IEEE Transactions on Industry Applications, 57(1), 208-217. https://doi.org/10.1109/TIA.2020.3028347

This research work investigates the phenomenon of interbar currents in induction motors equipped with die-cast aluminum cages. Flowing in the lamination and distorting the bar current distributions, the interbar currents cause additional stray losses...
