Electrical steels are soft magnetic materials found at the heart of electric motors. They’re typically manufactured in cold-rolled strips, cut into shapes to make laminations and then stacked together to form the stator and rotor of a motor. These specialty steels are tailored to produce certain magnetic properties, and have a magnetic flux density (key… Read more »

Taiwanese startup debuts road-legal electric supercar
The EV revolution is helping to spread the automotive industry all around the globe. XING Mobility is a Taipei-based startup that develops EVs technology through racing. The company, which includes some ex-Tesla engineers, released an electric race car prototype in 2015, and has since developed several EV products aimed at the commercial vehicle market. The… Read more »
Tesla’s chief motor engineer discusses the potential of next-generation motor technologies
Tesla spends a considerable amount of resources on basic research into EV systems – as well it should. EV technology is very young compared to that of ICE vehicles, so it’s safe to assume that, in a few short years, the aggregate of many incremental technology advances could lead to significantly better EVs. Of course,… Read more »
Silicon Mobility introduces software library for optimizing battery range and charging speed
France-based Silicon Mobility, a provider of semiconductor control solutions, has introduced a software library and an application optimized for its OLEA chips. OLEA is Silicon Mobility’s family of products for automotive applications, and includes a hardware-flexible interface for real-time data processing and deterministic control of actuators and sensors and SILant, as well as a functional… Read more »
AVID and GKN partner to further develop EVO motor
The English automotive clean tech firm AVID Technology has signed a deal with GKN Hybrid Power to develop and manufacture electric motors. AVID will take over the existing EVO motors, and develop EVO technology to deliver new variants of the motor. According to the companies, the EVO motor’s high power density, ability to run at… Read more »
Intel, Mobileye and Tesla’s stock price
Intel’s recent acquisition of Mobileye, an Israeli provider of autonomous driving technology, for $15 billion, has three interesting implications. The first is obvious: self-driving tech is expected to be huge, and companies are busily investing money and R&D efforts to position themselves as players. The second point, also apparent to observers in the tech world… Read more »
Southwest Research Institute consortium conducts independent battery benchmarking
Comparing the spec sheets from different parts manufacturers is tricky business for engineers in any industry. However, the advanced battery market seems to be uniquely challenged in this regard. As Tesla CEO Elon Musk often points out, when it comes to batteries, the BS factor is outrageous. Even if you assume that every vendor provides… Read more »
Wolfspeed launches a new silicon carbide MOSFET for EV inverters
Wide Bandgap (WBG) semiconductor technologies have attracted a lot of attention and research funding in the past decade. Both public and private institutions around the world have been obsessed with accelerating the evolution of WBG tech into commercial power electronics applications. What’s all the fuss about? WBG materials such as silicon carbide (SiC) and gallium… Read more »
Thermoelectric generators convert waste heat from an ICE to electricity
The Institute of Vehicle Concepts at the German Aerospace Center (DLR) is working with Yamaha to develop thermoelectric generator modules for on-road and rail vehicles. In “Development of a Thermoelectric Module Suitable for Vehicles and Based on CoSb3 Manufactured Close to Production,” published in the Journal of Electronic Materials, Mirko Klein Altstedde and colleagues explain… Read more »
Japanese automakers doggedly forge ahead with fuel cells
The debate over fuel cells rages on. Many in the EV industry, most prominently Elon Musk, have explained at eloquent length why hydrogen fuel cells are inferior to batteries for automotive applications. Others however, especially in Japan, do not agree. The main proponent is Toyota, which has been selling the Mirai fuel cell vehicle since… Read more »
