Nissan wants to reduce the production costs of electric cars by 30 per cent over the next few years in order to reach the price level of combustion engines. Among other things, the Japanese car manufacturer is focussing on the permanent magnets used in the rotor, which are made of rare earths. In particular, Nissan […]

Marsilli, a manufacturer of winding and assembly systems for electric motors, announced the development of Distributed High-Density (DHD) stator winding technology three years ago. Marsilli has now declared the technology mature. The company is involved in several pilot projects and is working with partners and customers on new projects to bring DHD stator winding technology

ABB announced the launch of a new package consisting of an the AMXE250 motor and an HES580 inverter specifically designed for electric buses. This is the first 3-level inverter for electric buses, which according to ABB offers higher energy efficiency and performance. Benefits of the new technology ABB claims a 75% reduction in motor harmonic

Cambridge Vacuum Engineering (CVE), a leading supplier of electron beam and laser welding systems, and automotive manufacturer Ford have been awarded a £430,000 research grant from national public funding body UK Research and Innovation. The grant is part of the £5.8 million awarded to UK Research and Innovation under the Innovate UK funding programme. The

General Motors has successfully patented an axial flux motor with a special hydraulic system for generating field weakening. The field weakening functionality allows the electric motor to be operated at higher speeds. The field weakening is typically implemented through inverter software, though this approach inevitably results in some losses. The objective of the mechanical systems

In order to enhance the efficiency of electric motors, reduce costs and minimise the utilisation of heavy rare earth metals, a research project with a budget of 2.6 million dollars has been initiated under the leadership of the University of Michigan. The researchers are employing a 3D printing process, namely ‘Laser Powder Bed Fusion’ or

BorgWarner is the first supplier to deliver a torque vectoring system with integrated axle deactivation (eTVD) for electric vehicles. It is being used for the first time in the Polestar 3 SUV and another major European OEM. The eTVD is part of the Electric Torque Management System (eTMS) and enables intelligent distribution of torque to

Together with project partners VTT, Siemens, Stellantis and Gemmate Technologies, Norwegian company Elkem has developed a soft magnetic powder for the production of electric motor stators. According to the manufacturer, the powder is based on silicon steel mixed with additives, is processed using powder bed fusion and is easy to magnetize and demagnetize. The innovation

A consortium led by Schaeffler and the Fraunhofer Institute IPA is working on the REASSERT project to develop an electric motor prototype that can be easily disassembled and therefore is suitable for the circular economy. By enabling a second utilisation phase of the electric motor and the materials used in it, the overarching goal is

At the Consumer Electronics Show (CES) in Aurora, Ontario, Canadian automotive parts manufacturer Magna International has presented its next-generation 800-volt drive concept which combines several innovative technologies. At the presentation of its “eDrive” at the world’s largest and most important technology event, the company claimed that it had reduced the weight by 75 kilograms compared

Duxion Motors is testing its patented eJet motor for electric aviation at low and high speeds. The eJet motor utilises permanent magnet technology and a new hybrid cooling system to achieve a better power-to-weight ratio for the electrification of jet aircraft. The integrated ducted fan system supplements the liquid cooling system with active convection cooling

Hyundai Motor and Kia have presented a jointly developed wheel-hub motor concept that is suitable for both passenger cars and shuttle vehicles. The technology is also intended to allow use as a skateboard platform, serving as the basis for different body types. Compact electric motor close to the wheel As with other wheel hub concepts,

Automotive supplier Continental and Munich-based start-up DeepDrive have founded a joint venture to develop an innovative wheel hub drive with an integrated brake. The aim is to meet the challenges of weight, costs, resource-saving use of materials, and installation space requirements in the design of drives for current electric vehicles. Working as central drive and

Electric motors play a key role in the mobility transition due to their high efficiency and zero emissions during operation. However, their weight, the installation space required to accommodate them, and, above all, their energy consumption have a significant impact on the ecological footprint of a vehicle. A decisive factor for the efficiency of an

The University of Duisburg-Essen, the Technical University of Darmstadt and the Helmholtz-Zentrum Dresden-Rossendorf are jointly researching new magnetic materials. In the “PUMA” project, the scientists are aiming to develop highly efficient magnets based on materials which are able to cool efficiently or generate heat and electricity without the use of rare-earth elements. Eco-friendly alternative to

Koenigsegg is presenting its latest innovation, the self-developed raxial flux motor, ‘Quark’. This unique motor consists of both a radial flux motor and an axial flux unit. According to Koenigsegg, this combination offers the optimal ratio of torque to power to weight. The standard version of the engine weighs just under 30 kg and is
