| Summary: | Research and development on hybrid excitation flux switching machines (HEFSM) for
various applications have been carried out in the last years. The designed HEFSM consist of
permanent magnet (PM) and DC field excitation coil (DC-FEC) which is located on the stator core
as their main flux sources, while a single piece rotor gives the advantages of robust rotor structure.
Since most of the designed HEFSMs utilize three-phase windings, more complicated design and
control system are required to run the motor. Thus, a new design of single-phase E-Core HEFSM
with several advantages of much simpler converter size and smaller battery package due to small
voltage capacity when compared with conventional three-phase system is proposed. Consequently,
the size of overall configuration systems will also be reduced resulting in reducing total weight and
cost. In this paper, initial performances of 4S-4P, 4S-6P, 4S-8P and 4S-10P E-Core HEFSM
topologies are analysed. Since 4S-10P design gives highest torque and power performances,
deterministic design optimization approach is conducted to enhance much higher and optimum
performances. As conclusion, the optimized E-core HEFSM with 4S-10P topology has achieved
maximum torque and power of 208.857Nm and 47.31 kW, respectively |
