| Summary: | A new structure of field excitation flux switching motor (FEFSM) as an alternative
candidate of non-Permanent Magnet (PM) machine for HEV drives is presented in this
thesis. Design principles and initial performances of the proposed motor with 12 stator
slots and 14 rotor pole are demonstrated. Initially, the coil arrangement tests are
examined to validate the operating principle of the motor and to certify the zero rotor
position. Furthermore, the profile of flux linkage,cogging torque, torque versus Ja at
various Je characteristics and torque versus power characteristics are observed and
analyzed based on 2D-finite element analysis (FEA). The improvement design is done
by using the “deterministic optimization method” to achieve the restriction and
spesification target compared to Interior Permenant Magnet Synchronous Machines
(IPMSM) that used in HEV drives. “The results obtained show that proposed 12S-14P
FEFSM achieved the target performance for maximum power, maximum torque density,
maximum power density and machine weight, while the maximum torque is not
achieved as a target. Therefore, by further design modification and optimization it is
expected that the low cost motor will successfully achieved the target performances. |
