Electrical Machine Slot Thermal Condition Effects on Back Iron Extension Thermal Benefits (2021)
Journal Article
Zhang, F., Gerada, D., Xu, Z., Tighe, C., Zhang, H., Yan, L., & Gerada, C. (2021). Electrical Machine Slot Thermal Condition Effects on Back Iron Extension Thermal Benefits. IEEE Transactions on Transportation Electrification, 7(4), 2927-2938. https://doi.org/10.1109/tte.2021.3085822

The slot thermal condition is critical for thermal management of high-performance electrical machines, due to the high heat losses and poor heat transfer ability within the slot. With a part of the back iron projected radially downward into the slot,... Read More about Electrical Machine Slot Thermal Condition Effects on Back Iron Extension Thermal Benefits.

Equivalent Slot Thermal Conductivity and Back-iron Extension Effects on Machine Cooling (2019)
Presentation / Conference Contribution
Zhang, F., Gerada, D., Xu, Z., Zhang, H., & Gerada, C. (2019, August). Equivalent Slot Thermal Conductivity and Back-iron Extension Effects on Machine Cooling. Presented at 2019 22nd International Conference on Electrical Machines and Systems (ICEMS), Harbin, China

Back-iron Extension (BIE) is an effective thermal management technique which reduces the winding temperatures by projecting part of the back iron into the center of slot, thereby shortening the heat transfer path between the coil and back iron. Based... Read More about Equivalent Slot Thermal Conductivity and Back-iron Extension Effects on Machine Cooling.
