“…flux-weakening and flux enhancing capability are achieved with the help of field excitation current makes HE-FSM competent candidates for variable speed applications [3,4] especially in Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs). In addition, flux controllability provides ratio of the PM flux and field excitation winding flux which results investigation of wide constant power speed range [5,6]. Based on the aforesaid merits of HE-FSM, this paper solely focuses on detail investigation regarding structure variations as well torque and power capability of HE-FSM for EV and HEV applications.…”

“…Hence, to combine the merits of PM-FSM and FE-FSM machines the PM and FE are coexist, and the concept of hybrid excited HE machines have been proposed. HE machines are admirable applicants for variable speed applications, such as electric vehicle, aircraft and wind power generation [16], [17]. There are a numerous number of topologies of HE machines have been introduced and published, because of two excitation sources PM and FE can be arranged in various techniques and arrangements.…”

All electric aircraft (AEA), is one of the main intentions of the aerospace industry for future. Where electrical machines are capable to provide high torque density and are dominant for the feasibility of direct drive electrical driving force for aircraft applications. Besides, low weight and high torque capabilities, the best candidate solution should also inherently fault tolerant for aircraft applications. For these reasons, a new sort of machine has been familiarized and published in last decade know as flux switching machine (FSM). FSMs contain all excitation sources on stator side with robust rotor structure. According to the type of excitation, FSMs are characterized into three types such as permanent magnet PM FSM, field excitation FE FSM and hybrid excitation HE FSM. PM FSM and FE FSM use PM and FE coil for their excitation sources respectively, whereas both PM and FE coil is used in HE-FSM for excitation. Subsequently, these machines have shown high torque to weight ratios and high efficiency during research in the last decade. Therefore in this paper, a new structure of 12S-8P HE-FSM with segmental rotor has been proposed and analyzed. The proposed segmented HE-FSM has the simple structure using only three PMs and three FECs. The proposed structure is analyzed using commercial 2D FEA package, JMAG-designer ver. 14.0. This paper presents the coil test analysis of segmented HE-FSM to confirm the working principle. Besides, cogging torque, flux strengthening, torque vs current densities and power vs current densities have been analyzed and presented.

To decrease the influence of air transport on the environment as well as to improve fuel efficiency moreelectric aircraft (MEA) architecture is a well-known approach. Due to the fact that electrical machines are capable to provide higher torque densities and are dominant for the feasibility of direct drive electrical driving force for aircraft applications. For these reasons a new sort of machine has been acquainted and published in last decade well-known as flux switching machine (FSM). FSMs comprises all excitation sources on stator side with winding less robust rotor structure. Further FSMs are characterized into three types such as permanent magnet (PM) FSMs, field excitation (FE) FSMs and hybrid excitation (HE) FSMs. PM FSM and FE FSM use PM and FE coil for their excitation sources respectively, whereas both PM and FE coil are used in HE-FSM for excitation. Subsequently, HE FSMs have shown higher torque to weight ratios with higher efficiency during research in the last decade. Nevertheless, in existing structures of HE FSMs using segmental, there is flux cancellation between the fluxes of PMs and FE coil which causes to reduce the performance of machines. Hence, in this paper, a proposed structure of HE FSM with segmented rotor has been proposed and analyzed. The proposed HE FSM has a simple structure using three PMs and three FECs. The proposed structure has been analyzed using commercial 2D FEA package, JMAG-designer. Initially, this paper presents the coil test analysis of novel HE FSM to confirm the working principle. Besides, performance of proposed HE FSM has been analysis and comparison with existing HE FSM at no load and load conditions. 
