“…The design specifications and operation of 8S-4P SFWFM is explained in [36]. When compared with induction machine, the SFWFM has achieved high torque and efficiency but the main problems concerned with this design are low starting torque, high torque ripples, overlapped windings, and fixed rotating direction.…”

“…It is shown that the iron loss of SFWFM has been reduced and thus increased the efficiency. These machines share the same operating principle as discussed in [36], but 12S-6P explained in [37] has much shorter end windings, and therefore, much better copper usage efficiency. These topologies have problems of overlap windings and high copper losses.…”

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.

“…Since HE-FSM used a hybrid excitation flux source, the machine has a potential to produce a higher torque output and power density, improve flux weakening performance, increase efficiency and more flux variable capability. It have been studied by most researcher broadly over a decade [8][9][10][11][12][13]. Figure 2 illustrates several HE-FSMs topologies that have been designed.…”

This paper presents performance analysis of 12Slot with various rotor pole numbers Hybrid Excitation Flux Switching Machine (HEFSM) for Hybrid Electric Vehicles (HEVs) application. HEFSM has carried out by combining the advantage of Permanent Magnet (PM) machines and DC Field Excitation Coil (FEC) synchronous machines. Previously, most of HEFSM structure having FEC windings in theta direction that create a problem of flux cancellation that will affect the performances of the machine. Thus, a design of 12Slot HEFSM with FEC wounded in radial direction is proposed to eliminate the flux cancellation effect. At first, armature coil arrangement test at no-load condition is conducted to analyze PM flux. Furthermore, induced voltage and cogging torque at open circuit condition are investigated based on 2D finite element analysis (FEA). Finally, torque and power performances are also examined at maximum FEC and armature current densities. The outcomes demonstrate that 12S-14P configuration has the highest PM flux linkage, torque, power and less distortion of back-emf waveform which are required to be used as a motor in HEVs. The highest torque and power achieved are 220.15Nm and 92.45kW, respectively.

“…Since the DC FEC is excited by unipolar current, it can be directly connected in parallel or in series with the dc-supply of power converter which feeds the bipolar current into the armature winding. The design principle is explained in [14], and the single-phase 8S-4P FEFSM has achieved higher output power density and much higher efficiency when compared with the induction machine (IM). However, the single-phase FEFSMs suffer with problems of low starting torque, large torque ripple, fixed rotating direction, and overlapped windings between armature coil and DC FEC.…”
