“…This design has significant gains over other designs as it utilize less conductor materials, thus improved the overall efficiency due to reduction of copper loss. SFWFMs with single and dual polarity FEC were discussed in [28,30], as illustrated in Figures 7 and 8. The advantages of SFWFM with single polarity FEC are low copper loss due to less volume of FEC, less leakage flux when compared with dual FEC windings.…”

This paper explains the state of art of switched flux wound-field machines (SFWFMs). The main advantage of these SFWFMs when compared with induction machines, synchronous machines, direct current machines, etc. is that all the active parts such that armature coil and field excitation coil are located on the stator while the rotor part consists of only iron material without windings. This makes the machine more robust, simple structure, and more suitable to be used for high-speed applications, compared to induction machine which has low mechanical strength, less torque desnity, and low power factor. Theories, numerical and technical literature of different SFWFM are described and analysed. Merits and demerits of different SFWFM structure are discussed. This paper categorized SFWFM topologies on the basis of their structure, flux linkage, cogging torque, average torque, and efficiency.

“…In order to avoid the risks, the continuous researches and developments on a new non-PM machine with high torque and power densities, high efficiency, robust rotor structure for highspeed operation is very important. As one of candidates of non-PM machine, many researchers have paid attention to wound field flux switching motors (WFFSM) [1]- [4].…”

This paper presents experimental drive performances evaluation of wound field flux switching motor for hybrid vehicle drive applications. A test machine with the maximum torque of 210Nm and the maximum power of 123kW expected at its design stage is built. A various experimental test result is demonstrated from viewpoints of the maximum torque and the maximum power capabilities and the motor efficiency up to its base speed of 6,000r/min. As a result, it is confirmed that the test machine promises well as a machine with very high power density more than 4.2kW/kg at the maximum power point under water jacket cooling.

“…Consequently, the government and related agencies have introduced more stiff standards to restrain the setback of emissions and fuel efficiency. On the other hand, in order to obtain a wide-range of full-performance and high efficiency vehicle while eliminating pollutant emissions, the most feasible solution at present is electric vehicle (EV) which are driven by battery-based electric motor [6][7][8]. Since electric motor is the key of an EV, SFM has recently become a well known and attractive design of machine type due to their numerous advantages such as low level of vibration and acoustic noise, high torque density and efficiency [7][8][9][10][11].…”

Currently, an interest in electric vehicles (EVs) exhibited by automakers, government agencies and customers make it as more attractive research. This is due to carbon dioxide emitted by conventional combustion engine that worsens the greenhouse effect nowadays. Since electric motors are the core of EVs, it is a pressing need for researchers to develop advanced electric motors. As one of the candidates, switched flux machine (SFM) is initiated in order to cope with the requirement. This paper proposes a new alternate circumferential and radial flux (AlCiRaF) of permanent magnet switched flux machines (PMSFM) for light weight electric vehicles. Firstly, AlCiRaF PMSFM is compared with the conventional PMSFM based on some design restrictions and specifications. Then the design refinements techniques are conducted by using deterministic optimization method in order to improve preliminary performance of machine. Finally the optimized machine design has achieved maximum torque and power of 47.43 Nm and 12.85 kW, respectively, slightly better than that of conventional PMSFM.
