“…A nonlinear time-varying magnetic circuit describing the FSPM behavior was built in [23] and allows an effective investigation of the DSPM electromagnetic performance. A quantitative assessment of FSPM performance against that of the traction motor of the Prius 2004 (interior-PM motor) has been conducted in [24], finding that the torque per volume of FSPM can match the counterpart of the interior PM (IPM) motor and that the torque ripple of FSPM is less than that of the IPM motor.…”

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.

“…Figure 1 shows the RE-EV system, which applies the in-wheel direct drive architecture. Based on the requirements of a typical passenger RE-EV, the targeted specifications of the system for each of the motors are listed in Table 1 [27,28]. This RE-EV system utilizes the motors as the major power source for the normal operations, while the ICE served as the supplementary part for range extension.…”

“…These confirm that the proposed machine can fulfill the torque requirements of normal operation, including the Mode 1, the torque boosting mode. Consequently, the torque ripples at rated and at strengthened DC-field excitation can be found to be 27.4% and 43.2%, respectively, which are both very acceptable for normal RE-EV applications [13,28].…”

Abstract:A new magnetless axial-flux doubly-salient DC-field (AF-DSDC) machine is proposed and implemented into the application of a range-extended electric vehicle (RE-EV). By employing the radial active part for the torque production, the proposed machine can produce satisfactory torque density to fulfill the requirements of the RE-EV system. With the support of the 3D finite element method (3D-FEM), the performances of the proposed machine are calculated and compared with the requirements of the typical passenger RE-EV applications. To offer a more comprehensive illustration, the common radial-flux (RF) machines are included for comparison.

“…Interior permanent magnet (IPM) motors are considered to be an excellent candidate for tractions of electric vehicle (EV) due to their high efficiency, high torque/power density and wide constant power speed range (1) . The requirements of lightweight and compactness for EV powertrains lead to high speed design of traction motors and this would require the iron loss to be minimized to maintain the efficiency.…”

This work investigates the impact of thin electrical steel laminations on the performance of interior permanent magnet (IPM) motors for electric vehicle tractions. Three different electrical steel grades are used in IPM motor designs and the performance is evaluated by simulation. It is found that thin laminations can improve the efficiency of the IPM motor, but the output torque could be slightly reduced due to low saturation flux density. Therefore, direct replacement of core materials for the same motor design may not be suitable. This paper presents the considerations for the design of IPM motors using thin laminations. The motor performance, including torque, efficiency, and constant power speed range is evaluated. A process is developed for the design of high performance IPM motors using thin laminations. Experimental studies are conducted to validate the simulations and designs.
