“…With all active components such as PM, DC field excitation coil (DC FEC), and armature coil located on the stator, the machine becomes extremely robust in which only single piece of rotor iron is employed. Various applications of FSM have been reported, ranging from wind power generation, automotive, aerospace, power tools and etc [11][12][13][14]. Generally FSMs can be classified into three groups, namely permanent magnet (PM) FSMs, hybrid excitation (HE) FSMs, and field excitation (FE) FSMs.…”

Abstract-Research on flux switching machines (FSMs) has been an attractive topic recently due to tremendous advantages of robust rotor structure, high torque, and high power capability that suits for intense applications. However, most of the investigations are focusing on inner rotor structure which incongruous for direct drive applications. In this paper, the design optimization and performance analysis of 12Slot-14Pole hybrid excitation flux switching machine (HEFSM) with outer-rotor configuration are conducted for in-wheel direct drive electric vehicle (EV). Similar with conventional inner-rotor HEFSMs, two magnetic flux sources of permanent magnet (PM) and field excitation coil (FEC) have extra advantage of variable flux control capability, while the outer-rotor configuration has ability to provide much higher torque and power density suitable for inwheel EV drives. Based on some design restriction and specification, design refinements are conducted on the initial design machine by using deterministic optimization approach. The final design machine has achieved maximum torque and power density of 335.08Nm and 5.93kW/kg, respectively, slightly better than inner rotor HEFSM and interior permanent magnet synchronous machine (IPMSM) design for EV.

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.

“…They can be also an interesting option in some applications of distributed generation. They combine the best of switched reluctance machines (simplicity constructive of the rotor) with the best of the brushless DC motors and/or the synchronous permanent magnet machines (high torque/power density) [1][2]. This paper deals with hybrid reluctance machines, which are based on the combination of some previously known technical contributions as:…”

Abstract. This paper is about hybrid reluctance machines, in which the stator or fixed part has a combination of U-shaped electromagnets with permanents magnets placed between their arms while the moving part is simply a structure with salient poles. They can be designed to build different types of rotary or linear electric motors and generators with outstanding performances. In this paper, first, the principle of operation of these machines is explained. Then different types of hybrid reluctance machines using this particular structural configuration are described showing their potential based on simulations and experimental results.
