Electric Machines and Drive Systems for Electrified Vehicle Systems
All dates for this event occur in the past.
This is a virtual seminar being held via Zoom
Speaker: Dr. Julia Zhang, Associate Professor, Department of Electrical and Computer Engineering, The Ohio State University (OSU)
Abstract: This talk will introduce ac electric machines and drive systems, and their advanced application examples in electrified vehicles including road vehicles and aircraft. We will discuss the strong need of multi-disciplinary research between electrical, mechanical, and material engineers to meet the system requirements of electric machines for these new applications such as high mechanical speed operation (10000 rpm to 30000 rpm), high specific power of machines >14 kW/kg including the cooling hardware, high efficiency >95%, high operating temperature >200°C for some applications.
