| Summary: | Permanent magnet flux switching machine
(PMFSM) with additional field excitation coil (FEC) has several
attractive features compared to conventional permanent magnet
(PM) machines because of its variable flux control capability and
robust rotor structure suitable to apply for high speed
applications. However, the original machine has a limitation of
operating in high current condition due to nonessential magnetic
saturation that prevents the machine from extracting the
maximum performances. To overcome this problem, some design
refinements are conducted by using deterministic optimization
method to gain a better performance in the maximum torque and
power production. The results simulated by finite element
analysis (FEA) show that the machine with the improved design
increases by 11.6% of the maximum torque and 16.3% of the
maximum power compared to the original design. |
