DESCRIPTION:Speakers: Liang Xin (Huazhong University of Science and Techno
logy)\nHomopolar synchronous machine (HSM) has a solid rotor with no perma
nent magnet\, winding and any other components. Therefore\, the HSM has th
e merits of high speed operation\, high energy storage density\, brushless
excitation\, reliable structure\, etc. However\, when the HSM is analyzed
and optimized by finite element analysis (FEA)\, the 3-D magnetic flux di
stribution in the HSM leads to the great demands on the computation resour
ce and time. In order to solve the aforementioned problem and simplify the
analysis\, a 2-D equivalent mode is proposed in this work. Firstly\, the
method of air-gap flux density spatial overlay analysis is proposed and il
lustrated. Afterward\, based on the above analysis\, the structure and equ
ivalent principle of 3-D to 2-D mode are investigated\, such as the rotor
structure\, the value of exciting current\, and so on. Finally\, the air-g
ap flux density and back electromotive force of 2-D mode and corresponding
3-D mode are calculated by FEA. An experimental platform of HSM is also c
onstructed to validate the proposed 2-D mode. The simulation and experimen
tal results show that the proposed 2-D model can be equivalent to the 3-D
HSM\, which would be helpful for the design and optimization of this kind
of machine.\n\nhttps://indico.cern.ch/event/445667/contributions/2563014/
