Abstract
50493-98-I Passive Phase-Change Augmented Thermal Management Scheme for Induction Motors--SatCon Technology Corporation, 161 First Street, Cambridge, MA 02142-1207; (617) 661-0540 Dr. Edward J. Ognibene, Principal Investigator Mr. David B. Eisenhaure, Business Official DOE Grant No. DE-FG02-98ER82660 Amount: $74,975 Substantial power density improvements are needed to meet Partnership for a New Generation of Vehicles (PNGV) goals. In particular, an economically viable eighty mile-per-gallon hybrid electric vehicle is needed for the automotive industry. This project will develop a novel phase change-augmented thermal management scheme for induction motors that will increase power density and reduce cost per kilowatt by decreasing required magnetic material and overall motor weight per given power output. In addition to using a conventional water jacket, this scheme will employ passive phase-change heat transfer in the stator end-turns. Thus, peak temperatures and thermal gradients will be dramatically reduced, leading to increased power density and reduced cost. Phase I focuses on developing a practical thermal-fluid model of this innovative end-turn cooling scheme that will enable the synthesis of optimal motor designs. Proof-of-concept experiments will be conducted to verify theoretical assertions and determine the appropriate material(s) and configuration for this cooling scheme. A preliminary design of a 100 kW traction motor will be produced. Prototype construction and testing is planned for Phase II. Commercial Applications and Other Benefits as described by the awardee: This technology should contribute to the overall goal of producing a commercially-viable hybrid electric vehicle for the automotive industry. Other applications include high-power industrial drives, turbo-alternators, and other power-dense machines. The technology should also be applicable to other high power density equipment such as power electronics._
