“…The average torque achieved by 12S-14P SFWFM with toroidal DC winding is far better than the designs discussed before but this machine has high torque ripples which should be consider in future for better characteristics [40]. Recent research has shown that single-phase SFWFMs [38] and outer rotor SFWFM [42] have less iron losses, copper losses, less weight, and high efficiency but the average torque of proposed topologies needs improvement. In [43], the author analysed a new structure of SFWFM which has non-overlap armature and field windings and the rotor is robust.…”

“…The cogging torque reduction techniques are normally chosen with the conditions of easy implementation, minimum cost, and machine performances. Various techniques have been published to reduce the cogging torque on both radial-type [52À54] and axial-type PM SFM [55], left vacant space in the area of SFWFMs, as all the designed discussed above have cogging torque especially single phase SFWFMs which have high cogging torque, discussed in [38]. Rotors with stepped skew [56,57] should be adopted in future to reduce the cogging torque and torque ripple under various load conditions.…”

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.

Design, optimization, and performance analysis of a three-phase field-excited flux switching (FEFS) motor to be employed for the future hybrid electric vehicle (HEV) drive applications is investigated in this paper. The stator of designed motor made of electromagnetic steels is composed of unique field mmf source and armature coils while a rotor is made of iron stack. This design has been evaluated in order to achieve power and torque density higher than 3.50 kW/kg and 210 Nm, respectively, so as to compete with the interior permanent magnet synchronous (IPMS) motor commonly installed in HEV. Given its robust rotor structure, the maximum achievable motor speed went up to 20,000 rpm. To perfect the motor design, a deterministic optimization approach was applied to meet the stringent performance requirements. In addition, experimental analyses were carried out to confirm the effectiveness of the proposed motor. Positively, the proposed FEFS motor has proved to be a suitable candidate of non-permanent magnet motor for efficient and safe HEV drive.

“…In order to reduce the cost, one of the possible solutions is to replace the PM with a field excitation coil (FEC). For this reason, some wound field FSMs are proposed for low-cost applications [8][9][10]. The wound field FSM is a novel brushless machine having windings located in the stator [11], having advantages of a magnet-less machine, simple construction, low cost, and variable flux control capabilities suitable for various applications when compared with other FSMs.…”

A flux switching machine (FSM) with a segmented rotor and nonoverlapping 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, while a FSM with salient rotor and overlapping windings inherits high copper losses and less efficiency due to high coil volume. In this paper, a novel structure of FSM with nonoverlapping windings and salient rotor is proposed, making it different from the 10Slot-8Pole segmental and salient rotor FSM. Several design parameters defined in the rotor, armature coil, and field excitation coil are treated by the deterministic optimization approach until the target values are achieved and the performances are analyzed by two-dimensional finite element analysis. The optimized design has achieved average torque of 27.06 Nm and power of 6.83 kW at armature current density, Ja , of 30 A rms /mm 2 and maximum field current density, Je , of 30 A/mm 2 , which is greater than the 10Slot-8Pole segmental rotor and salient rotor FSM. Wound field FSMs with salient rotor and nonoverlapping windings should be considered as promising candidates for hybrid electric vehicles and all-electric boats due to their high torque density, robust rotor, and fewer losses.
