Three-phase field excitation flux switching motor (FEFSM) with salient rotor structure has been introduced with their advantages of rotor easy temperature elimination and controllable FEC magnetic flux. Yet, the salient rotor structure is found to lead a longer magnetic flux path between stator and rotor parts, producing a weak flux linkage along with low torque performances. Hence, a new structure...
Hybrid Permanent Magnet Flux Switching Machine (HPMFSM) is a machine that uses two permanent magnets which are Ferrite Permanent Magnet (FPM) and Rare Earth Permanent Magnet (REPM). The REPM had being implemented widely in HEV nowadays. So, HPMFSM is created in order to reduce the volume of REPM itself. Three designs had created which are PM, PMH and SMH design. PM only consist of REPM, meanwhile...
Plug-in hybrid electric vehicle (PHEV) is independent of the internal combustion engine but acts as the auxiliary unit mostly on the electric drive system. Main while, the Flux-switching permanent magnet machine (FSPMM) has been studied in terms of structure with its operation principle been analyzed. To achieve a higher torque with a corresponding high power density and lower torque ripple, FSPMM...
Hybrid Excitation Flux Switching Machine (HEFSM) is a machine that achieves high performances, where it can compete with the Interior Permanent Magnet Synchronous Machine (IPMSM) which being implemented widely in HEV nowadays. The machine also when compared to Field Excitation Flux Switching Machine (FEFSM) and Permanent Magnet Flux Switching Machine (PMFSM), generate much higher performance mainly...
Research and development on flux switching machines (FSM) for several applications have been carried out by the researchers in recent years. According to excitation source the FSMs are classified in three types' permanent magnet PM FSM, field excitation FE FSM and hybrid excitation HE FSM. In recent development of research has been with toothed rotor structures which exploits changes of paths for...
Rotor is one of the core component in flux switching machine (FSM) that wield mechanical stress. It is very important to identify the maximum tensile strength of the rotor. Beyond the maximum tensile strength, the rotor will deform or crack. In the research, stress analysis for the tensile strength is measured through principal stress. The stress analysis is conducted to analyze the principal stress...
Increasing transportation efficiency is the best place to start efforts to reduce emission of carbon dioxide (CO2), which is a primary culprit in global warming. This has gained an interest in electric vehicles (EVs) instead of conventional internal combustion engine from automakers, governments and customers to make it as more attractive research. Since electric motors are the core of EVs, it is...
This paper comprehensively investigates methodology of 3D FEA model of a novel 12Slot-10Pole wound field flux switching machine (WFFSM) with salient rotor and non-overlapping windings (SalRoN) and compared the results with 2D FEA. This machine does not require slip-rings or brushes and combines the stator of WFFSM with segmental rotor and non-overlapping windings (SegRoN) and rotor of WFFSM with salient...
A flux switching machine (FSM) with a segmented rotor and non-overlap windings is an attractive alternative for driving high torque density applications. However, a rotor with segments makes the motor less robust as well as difficult to be assembled, whilst, FSMs with salient rotor and overlap windings inherit high copper losses and less efficiency due to high coil volume. In this paper, performance...
Single-phase Field Excitation Flux Switching Machines (FEFSMs) are increasingly considered as suitable candidate for high speed applications due to their variable flux capability and single piece structure of rotor. However, most of existing FEFSMs have overlap windings between armature and field excitation coil (FEC) which lead to increased size of motor, copper losses as well as material costs....
Dual Rotor Hybrid Excitation Machine (DRHEFSM) idea mainly comes from the existing Hybrid Excitation Flux Switching Machine (HEFSM). HEFSM has been tested and obtain remarkably result. The machine rivaled the Interior Permanent Magnet Synchronous Machine (IPMSM) and produce high performance when compared to Field Excitation Flux Switching Machine (FEFSM) and Permanent Magnet Flux Switching Machine...
Research and development on flux switching machines (FSMs) getting popular due to their several definite advantages of high torque and power densities, constant power over a wide speed range, higher efficiency and robust rotor structure inherits combined advantages of permanent magnet synchronous motor (PMSM) and switched-reluctance motor (SRM). There are many developed and novel design of FSMs for...
Hybrid electric vehicles (HEVs), using combination of an internal combustion engine (ICE) and one or more electric motors, are widely considered as the most promising clean vehicles. The only machine that already installed for HEVs is interior permanent magnet synchronous machine (IPMSM) where it has developed to enhance power density of the machine. Despite of fine operated and superior performances,...
