“…At the rated current (I max = 10 A), 120 Udc voltage, and greater machine speed set at 6000 rpm, the approach described in Refs. [10,11] is used to examine the torque against speed and power versus speed waveshapes of the proposed machine. The comparison of the CPSR performances for the initial and optimised topologies is shown in Figure 14.…”

“…On the other hand, the IPM synchronous machines are highly versatile and well-suited for numerous electric vehicles (EVs) due to their magnetic saliency, which enables them to generate torque by utilising both the PM and reluctance torque. These qualities have subsidised to the increasing popularity of IPM synchronous machines as the preferred choice for driving Electric Vehicles, including models like Lucid, Camry, Leaf, Honda-Accord, Mitsubishi-Outlander, Renault Zoe, Audi-e-Tron, Porsche-Taycan, Tesla Model-3, Toyota Prius 2010 model, and others [5][6][7][8][9][10][11].…”

A novel asymmetric delta‐type and Spoke‐type interior permanent magnet synchronous machine (ASD‐IPM) is proposed for electric vehicles (EVs) application that uses the magnetic field shifting technique to maximise the average torque and lessen torque ripples. The proposed ASD‐IPM is deduced from the conventional asymmetric spoke and V‐shape IPM by attaching additional asymmetric flux barriers (AFB) to the left side of the spoke‐type PMs and to the other side of the delta‐type PMs. This configuration helps in reducing the leakage flux and achieving good flux concentration. The proposed design is optimised through a Genetic Algorithm (GA) to investigate the electromagnetic performances at no‐load and on‐load conditions. Also, the efficiency maps of both the proposed design and conventional design are analysed and compared. The results show that the proposed ASD‐AIPM has superior efficiency and a favorable torque profile, making it a suitable choice for electric vehicle applications. Furthermore, the proposed design is rescaled to the Toyota Prius 2010 design, with the only change in the slot/pole pair combination due to the presence of spoke‐PMs in the proposed design. The proposed ASD‐IPM achieves 7% higher torque than the existing Toyota Prius 2010 model. The efficiency maps of the rescaled design are also analysed and compared.

“…So, both SPM and IPM are more expensive than asynchronous induction motors (IMs). Nevertheless, automotive industry is now greatly interested in the reduction of rare-earth magnets, especially in high-grade ones, due to unreliable supply chains and price instability [86], [87]. Furthermore, high temperature class magnets must be used to achieve the needed overload capability, and a particular care must be given not to demagnetize them.…”

Today, agriculture industry has a significant impact in global greenhouse gas emissions. A large amount of pollutants come from diesel internal combustion engines, widely used in agricultural machinery. Since mechanization in agriculture is fundamental to achieve a proper food production for a growing human population, changes are needed in common agriculture engineering thinking in order to develop new farming machinery that could outperform conventional ones in terms of environmental impact, as well as performance, productivity and safety. Electrification is a feasible solution. A comprehensive review about agricultural machinery electrification is reported in this paper, with a particular focus on hybrid electric tractors and their implements. The introduction of electric drives in farming tractors is discussed in detail by looking at the main findings in literature and considering state-of-the-art technology. Proposals and prototypes from manufacturers are covered too, as well as economic assessments and future trends.

“…The reason why PMSMs have this advantage is because of the high energy density neodymium magnet used in their rotors. However, the high cost of neodymium magnets and the large disadvantage of PMSMs is that almost all of the neodymium reserves are in China [38]. IMs are the most preferred electric motor topology not only in electric vehicles but also in all applications due to their simple and robust structure, high efficiency at high speeds and the ability to produce high maximum torque similar to PMSMs [38][39].…”

With technological developments and carbon emission reaching dangerous levels in the world, it is inevitable that electric vehicles will become the dominant transportation technology of the future. Studies on electric vehicles have become very popular today. In the automotive sector, sectoral dynamics and needs are rapidly changing; restrictions and demands are bound by strict rules and high value-added innovative studies are applied intensively. Supporting this area with academic data will contribute to research and development activities in this field. In this study, analysis and production studies were performed on a 3-wheeled vehicle chassis driven by electric energy. The chassis structure was designed and analyzed with details. The chassis aimed to be produced as a result of the study was analyzed in detail according to brake, modal and cornering analysis. As a result of these analyses, it was found that this chassis has a reliable structure according to the specified driving dynamics parameters. By adopting new requirements, technologies and analysis outputs for the system, a modular platform structure that can be used for various applications were created. The design and production processes of an innovative and applicable chassis structure for the electric vehicle ecosystem are given in detail.
