| Summary: | Hybrid excitation flux switching machines (HEFSMs) have a several advantages such as
robust rotor structure, high torque and power capabilities, and high efficiency suitable for light load
and heavy industry applications. However, the general structure of HEFSMs employed with three
main flux sources namely permanent magnet (PM), field excitation coil (FEC) and armature coil
located on the stator body causes high manufacturing cost. Therefore, a new non-PM field
excitation flux switching machine (FEFSM) consists of rugged rotor structure suitable for highspeed
operation with capability to keep similar torque and power density of HEFSM is proposed
and examined. In this paper, performances of both outer and inner rotor 12S-14P FEFSMs are
analyzed and compared. As conclusion, the inner-rotor topology provides much higher torque and
power when compared with outer rotor configuration |
