FREE Live Webinar/ 2020-Faraday Memorial Lecture on "High Power Density Electric Machines for Applications in Renewable Energy Systems & Hybrid Electric Aircrafts” / On 31-Oct-2020 / Saturday/ Evening/ From 5.30 PM to 7.45 PM (IST)

***************************

Significant improvement in electric machine power density has been made in recent years driven by emerging applications that are sensitive to size and weight of the electric power equipment. One such application is hybrid electric aircraft, which is being developed to meet ambitious emission reduction goals that have been set by the aviation industry. Small electric aircraft are already being produced and offered commercially, but significant challenges prevent electrified propulsion in commercial aviation. Technology gaps include the availability of lightweight batteries, motors, and power distribution hardware. In a recent report, the US National Academy of Engineers has identified power levels and specific-power targets for electrical machines to enable the electrification of different classes of aircraft. Both cryogenic (superconducting) and non-cryogenic machines are being pursued to meet these requirements. This talk will describe the state of the art in airborne electrical machines, approaches for attaining high power and efficiency, and potential challenges and opportunities in the integration of these technologies in electric/hybrid electric aircraft. Another application that is sensitive to electric machine power density, and at the other end of the speed spectrum, is large wind turbines. Technology synergy between these applications and development activities targeting further increase in power density will be discussed.

Brief Profile of the Invited Speaker:

**********************

Kiruba Sivasubramaniam Haran is a Professor of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign and Associate Director of the Grainger Center for Electrical Machines and Electromechanics. He obtained his BS in Electrical Engineering from OAU in Nigeria, and a PhD from RPI in Troy, New York, USA. Over the past six years Prof. Kiruba has been working with NASA and industry partners on high specific power motors and drives for electrified aircraft. Prior to this, he was at GE Research for 13 years, developing electrical machine technology for multiple GE businesses. His contributions include demonstration of a multi-megawatt superconducting generator for the US AFRL, which could enable a range of airborne applications including hybrid electric propulsion for large transport aircraft. Prof. Kiruba is a former chair of the Electric Machinery Committee of the IEEE Power and Energy Society, and currently serves on the Steering Committee of the IEEE Transportation Electrification Community, IEEE Council on Superconductivity, and the AIAA Aircraft Electrified Propulsion and Power Working Group. He is an IEEE Fellow and Associate Fellow of AIAA.
