Prof. Ronghai Qu

Ronghai Qu received his B.E. and M.S. degrees from Tsinghua University, Beijing, China, in 1993 and 1996, respectively, and the Ph.D. degree in electrical engineering from University of Wisconsin-Madison in 2002.

He had been with the General Electric (GE) Global Research Center, Niskayuna, NY as a Senior Electrical Engineer with the Electrical Machines and Drives Laboratory from 2003 to 2010.

He was the recipient of more than 11 GE GRC awards including EPST Technical Achievement Award, Outstanding Teamwork and Management Award.

In 2010 he joined Huazhong University of Science & Technology, Wuhan, China as a titled professor.

He is currently the member of academic degrees committee, director of State and Province Joint Engineering Research Center of Novel Electrical Machines, director of Electrical Machines and Control Engineering Department, director of Center for Advanced Electrical Machines and Drives (CAEMD), and deputy director of State Key Laboratory of Advanced Electromagnetic Engineering and Technology.

From 2012 to 2016, he served as deputy dean of school of Electrical & Electronic Engineering.

He is currently a member of ICEM NPO AdCom and the chair of IEEE Industry Application Society (IAS) Wuhan Chapter.

His research interests include Design and Drive of Electrical Machines.

He has published over 300 technical papers including 11 IEEE award papers and holds over 100 patents.

Dr. Qu is the IAS Distinguished Lecturer for 2019-2021, and one of the winners of IAS Outstanding Member Awards in 2019.

Highly-compacted Electrical Machines with Dual-mechanical-port & Dual-electrical-port

Industries often have a requirement of a drive system with two electrical machines, a clutch and a gearbox to change speed, transfer power among two mechanical shaft and electrical port(s), such as hybrid vehicle drive. This presentation will introduce a highly-compacted electrical machine, named Brushless Dual-mechanical-port Dual-electrical-port (BLDD) machine, with one stator winding set and two rotors, one inside the other. With unique machine topology and control techniques, two rotors can be controlled independently in term of speed, rotation direction, motoring or generating, or even directly transferring power from one shaft to the other. Anatomically, the BLDD machine is the combination of flux modulation machine and regular PM machine, and this unique construction leads to various operation modes and machine topologies. Furthermore, via special configuration and control strategy, multi working magnetic field harmonics is produced by one set of winding. This presentation will summarize the machine principle, topology, winding configuration and control strategy.
