Nowadays, research and development of hybrid electric vehicles (HEVs) become popular in effort to reduce the pollutant emissions that can cause global warming due to demand of personal transportation. One example of successfully developed electric machines for HEVs is interior permanent magnet synchronous machines (IPMSMs). However, IPMSM design tends to be difficult because the permanent magnet (PM) is embedded in the rotor core and also the distributed armature winding. Therefore, a new machine known as flux switching machine (FSMs) which categorized in three groups is proposed with advantage of robust rotor structure which suitable for high speed applications. Thus, a new structure of 12S-10P PMFSM is introduced and investigated. However, this machine has some drawbacks and influence in term of performances, 12S-10P PMFSM have been transformed to 12S-10P and 12S-14P with additional FEC. In addition, iron flux bridges is introduced, due to the developed C-Type HEFSMs has a problem of separated stator core which lead to difficulty in manufacturing design as well as flux leakage to the outer stator. In this research, performance of PMFSM and HEFSM are analyzed and compared by 2D Finite Element Analysis (FEA) using JMAG Designer ver.13.0, released by Japanese Research Institute (JRI). In order to achieve the target performance, deterministic optimization method is applied to improve the initial design. As a conclusion, HEFSM design has successfully achieved the target and power similar with IPMSM used in Prius „07 specifications. This machine can also be employed in motor with robust condition due to its high mechanical strength as well as high revolution speed such as a hybrid electric vehicle.
