“…This substantially benefits the torque density. The outer-rotor PMSM's net mass may be up to 15% smaller than the corresponding one of a motor with inner rotor [7]. The outer rotor motors are the primary choice in electrified applications as they reduce transmission losses both during propulsion and regenerative braking.…”

The extreme environmental issues and the resulting need to save energy have turned attention to the electrification of energy applications. One of the key components involved in energy efficiency improvements is the appropriate conception and manufacturing of electric machines. This paper overviews the electromagnetic analysis governing the behavior of permanent magnets that enable substantial efficiency gains in recent electric machine developments. Particular emphasis is given to modeling the properties and losses developed in permanent magnets in emerging high speed applications. In addition, the investigation of properties and harmonic losses related to ferromagnetic materials constituting the machine magnetic circuits are equally analyzed and discussed. The experimental validation of the implemented methodologies and developed models with respect to the obtained precision is reported. The introduction of mixed numerical techniques based on the finite element method intended to appropriately represent the different physical phenomena encountered is outlined and discussed. Finally, fast and accurate simulation techniques including aggregated lumped parameter models considering harmonic losses associated with inverter supplies are discussed.

“…In literature, this approach was mostly used for electrical machine design with two single responses. Several cases were presented where average torque was maximised (or maintained) while minimising torque ripple [8,21,22,26,58,75], cogging torque/force [9,14,34,48,85] or harmonic components in the machine [47,49,73,74]. Hwang et al applied this approach to maximise efficiency while minimising torque ripple [23,52] or cogging torque [24][25][26] while Zhu et al used the same approach for structural design [20].…”

There has been a considerable amount of research work on using the Taguchi method for electrical machine design in recent years. However, for the large community of electrical machine designers, this method is still less known. The purpose of this paper is to summarise the past and current research work of applying the Taguchi method in electrical machine designs. We attempt to give readers some insight into the advantages and disadvantages, challenges, current status and future perspective of the method.

“…Extracting simulated efficiency maps of the designs is the first step towards that goal, while embedding those maps in a vehicle model and simulating a realistic driving scheme is a more accurate way. [5,6,9]…”

Design optimization of traction motors for light electric vehicles over an operating point is an adequate way of achieving higher overall efficiency under a standard driving scheme of the vehicle. However, this work proves that a direct comparison of similar candidates regarding efficiency values under a predetermined operating point does not yield sufficient information on the economy achieved on a specific driving pattern per candidate. This paper presents a comparative study on three similar surface mounted permanent magnet in-wheel motor configurations. On a first step, these configurations are compared in terms of efficiency and performance over one operating point. On a second step, efficiency maps of the designs under study are utilized to provide a wider picture of their efficiency attributes. On the final step, the three configurations are simulated driving a prototype light electric vehicle in the Urban part of the New European Driving Cycle and the results are discussed.
