“…Figure 4 illustrates two representative topologies of stator-PM motors: doubly-salient PM motor (DSPM) and flux switching PM motor (FSPM). DSPM [7,8] is the simplest structure of stator-PM motor. In essence, DSPM can be considered as a combination of SRM and stator magnets, as shown in Figure 4a.…”

Abstract:The paper presents a number of advanced solutions on electric machines and machine-based systems for the powertrain of electric vehicles (EVs). Two types of systems are considered, namely the drive systems designated to the EV propulsion and the power split devices utilized in the popular series-parallel hybrid electric vehicle architecture. After reviewing the main requirements for the electric drive systems, the paper illustrates advanced electric machine topologies, including a stator permanent magnet (stator-PM) motor, a hybrid-excitation motor, a flux memory motor and a redundant motor structure. Then, it illustrates advanced electric drive systems, such as the magnetic-geared in-wheel drive and the integrated starter generator (ISG). Finally, three machine-based implementations of the power split devices are expounded, built up around the dual-rotor PM machine, the dual-stator PM brushless machine and the magnetic-geared dual-rotor machine. As a conclusion, the development trends in the field of electric machines and machine-based systems for EVs are summarized.

“…Since the 2D FE predicted self-inductance cannot account for the end winding inductance, it is slightly smaller than that measured by LCR meter [47]. However, this influence can be eliminated based on (30) for the calculation of the mutualinductance between phase A and B, MBA. Therefore, the 2D FE predicted mutual-inductance and that calculated based on on (30) agree well with each other in both prototypes.…”

“…The modulation of the salient rotor to the static open-circuit PM field and the rotating armature reaction field makes them synchronous to each other in the air-gap, generating average electromagnetic torque [8]. There are three types of stator-PM machines, including doubly salient PM (DSPM) machines having yoke-inserted PMs [30], [31], switched flux PM (SFPM) machines having toothsandwiched PMs [32]- [39] and flux reversal PM (FRPM) machines having tooth-surface-mounted PMs [40]- [42]. Compared with the DSPM and SFPM machines, the FRPM machines have an integral stator lamination, which is better for manufacturing.…”

It is found that a SPM type machine is recommended, since both PS-FRPM and MG machines operating in SPM modes have a higher phase back-EMF and hence torque than their RPM counterparts, respectively, as a result of a similar phase flux-linkage but a higher electric frequency since the iron piece number is larger than the PM pole-pair number. Moreover, a smaller gear ratio machine is preferred from the perspective of a higher power factor and hence a lower inverter power rating, as the conventional MG machines with higher gear ratios suffer from larger fluxleakage, higher synchronous reactance and hence lower power factors, as well as higher iron losses, than the PS-FRPM machines. However, higher gear ratio machines feature lower cogging torques and torque ripples due to the smaller difference between the PM pole-pair number and iron piece number. Both prototypes of PS-FRPM machine operating in SPM mode and MG machine operating in RPM mode are built and tested to verify the FE predicted results.Index Terms-Flux modulated machine, flux reversal, magnetically geared (MG) machine, partitioned stator, permanent magnet (PM), power factor, rotor-permanent magnet, stator-permanent magnet.

“…1(a) shows a 6S-4P HEFSM in which the active parts are arranged in three layers in the stator. The inner stator consists of the armature windings, followed by the FECs in the middle layer, while the PMs are placed in outer stator [4][5]. However, it has low torque density and a long end winding for the DC FECs, which overlap the armature windings.…”
