“…Meanwhile, the torque obtained from 6S-5P and 6S-7P is more than 250Nm, while the torque achieved for 6S-4P and 6S-8P are far from the target. Thus, the deterministic optimization method mentioned in [15] is treated to all design repeatedly until the optimum performances are achieved. All final designs with optimum performance are illustrated in Fig.…”

“…FSM can be classified into three bunches that are Permanent magnet (PM) FSM, Field Excitation (FE) FSM and Hybrid Excitation (HE) FSM. Permanent magnet and field winding are the fundamental sources of flux in PMFSM and FEFSM, respectively while in HEFSM, both field winding and permanent magnet produces the flux [1]- [4]. In all these FSMs the armature winding and field winding or Permanent magnets are found on the stator.…”

Recently, a three-phase Field Excitation Flux Switching Motor (FEFSM) with salient rotor structure has been introduced with their advantages of easy rotor temperature elimination and controllable FEC magnetic flux particularly meet for high torque, high power as well as high speed diverse performances. Nevertheless, the salient rotor structure is found to lead a longer magnetic flux path between stator and rotor producing weak flux linkage along with low torque performances. Therefore, a new structure of a single-phase FEFSM using segmental rotor with non-overlap windings is proposed. Segmental rotor and non-overlap windings are the clear advantages of these topologies as the copper losses gets reduce and rotor becomes less weight as well as more robust. Detailed analysis on winding arrangement test analysis, armature and FEC flux linkage, back-EMF and average torque characteristics have been performed by using 2D Finite Element Analysis (FEA) through JMAG version 15 software. The results show that the proposed motor with segmental rotor and non-overlap windings produce short flux path, high flux linkage and the highest torque capability achieved is 0.91 Nm.

“…In general, FSMs can be classified into three groups, namely PM FSMs, hybrid excitation (HE) FSMs, and field excitation (FE) FSMs. Both the PMFSMs and FEFSMs have only single excitation flux source which either comes from the PM or FE coil, respectively, whereas in HEFSM there are two magnetic flux sources, which come from PMs and FECs [15].…”

In recent years, flux switching machines (FSMs) have been an attractive research topic owing to their tremendous advantages of robust rotor structure, high torque, and high power capability suitable for intensive applications. However, most of the investigations are focusing on the inner-rotor structure, which is incongruous for direct drive applications. In this study, high torque and power densities of a new 12S-14P outer-rotor permanent magnet (PM) FSM with a DC excitation coil was investigated based on two-dimensional finite element analysis for in-wheel direct drive electric vehicle (EV). Based on some design restrictions and specifications, design refinements were conducted on the original design machine by using the deterministic optimization approach. With only 1.0 kg PM, the final design machine achieved the maximum torque and power densities of 12.4 Nm/kg and 5.93 kW/kg, respectively, slightly better than the inner-rotor HEFSM and interior PM synchronous machine design for EV.
