SEMINAR

 

Diversity and Regularity of Topology Variations of Electric Machines

 Innovations, you can find it everywhere

 

Presented By: Dr. Weinong Fu, Associate Professor, EE Department, The Hong Kong Polytechnic University

Time/Date: 14:00 - 16:00/ April 8, 2015
Venue: Room 405, The Second Teaching Building (II)

Organizer: College of Electrical Engineering, Zhejiang University

 

Abstract: Exploring novel electric machines (EMs) with high efficiency, high torque density, and low cost is always an interesting research topic. In recent decades many different types of new EMs have emerged. Among others, these machines include a basic flux-modulated motor which uses the variation of magnetic reluctance to produce constant torque, a vernier motor which has special slot combinations, a doubly-fed magnetic reluctance machine which has two sets of windings on its stator, a flux-switching motor which has permanent magnets (PMs) on its stator, a dual-PM-excited motor with PMs on both rotor and stator. These machines have their own merits in specific applications. In this seminar, the internal relationships and operating mechanisms of  these machines will be scrutinized and all these machines will be summarized as general flux-modulated machines, as they all employ non-uniform magnetic reluctance to modulate their magnetic flux to produce constant torque. A general theory to explain the operating principle of all these machines will be proposed. The examples of its applications for developing novel electric machines will be presented.

      Seminar结束后,将利用5分钟左右的时间简要介绍香港理工大学电机工程学系招收MScPhD学生的情况。

 

About the speaker:

Weinong Fu received his PhD in electrical engineering from The Hong Kong Polytechnic University in 1999. He is now an Associate Professor in The Hong Kong Polytechnic University. Before joining the university in October 2007, he was one of the key developers at Ansoft Corporation in Pittsburgh, USA. He has about seven years of working experience at Ansoft, focusing on the development of the commercial software Maxwell. He has published over 160 papers in refereed journals. Dr. Fu's current research interests mainly focus on numerical methods of electromagnetic field computation, optimal design of electric devices based on numerical models, applied electromagnetics and novel electric machines.
