Induction Motor Power Loss Minimization Using Ripple Correlation Control

Published by . Filed under . Total of no comments in the discussion.

Ali M. Bazzi with adviser P. T. Krein This project investigates the application of ripple correlation control (RCC) to power loss minimization in induction motors. In many industrial applications induction motors are oversized and at light-load conditions efficiency drops significantly. Two tests were run on an induction motor before the application of RCC. The first […]

Windings for Surface-Mount PM Machines

Published by . Filed under . Total of no comments in the discussion.

Y. Duan, R. G. Harley and T. G. Habetler Georgia Institute of Technology, Atlanta, GA The use of both surface-mounted and interior-mounted magnet types of permanent magnet (PM) machines has grown significantly and there is a need for machines with higher efficiencies and larger power densities. The concept of concentrated stator windings (instead of the […]

Alternative Algorithms for Automated Electric Machine Design Tool Development

Published by . Filed under . Total of no comments in the discussion.

Tim O’Connell with adviser P. T. Krein The transportation industry is currently making a large push to “electrify” its fleets by developing hybrid electric vehicles (HEVs) and “more-electric” aircraft. The U.S. military is also funding several projects aimed at producing an all-electric battleship. Such endeavors, and many others across industry, require improved, specialized electric drive […]
