There seems to be an endless array of electric motor topologies, architectures, and configurations. Among the many design choices that engineers face is the shape of copper wire that is wound in the stator. In a new paper published in the IEEE Transactions on Industry Applications, researchers compared using flat wire hairpin winding and stranded… Read more »

Wildcat sorts through the avalanche of new battery materials to find the best
As automakers and cell manufacturers begin to realize the complexity of benchmarking new battery materials, Wildcat Discovery Technology is using its high-speed R&D technology to help find clarity If you follow battery technology news on a regular basis as we do, it’s easy to get overwhelmed by the volume of new announcements. There are… Read more »
A look at Lucid Motors: Q&A with CTO Peter Rawlinson
The legacy automakers are slowly and methodically developing new EVs, with various levels of enthusiasm, but the most ambitious plans for new vehicles are coming from a handful of EV startups. Most of these pioneers of the new auto industry share a formula: deep-pocketed investors (many from China), former Tesla employees on staff, and plans… Read more »
What’s the current state of wireless EV charging?
By Lisa Jerram, principal research analyst overseeing Navigant Research’s Transportation Efficiencies program Wireless charging is becoming more mainstream among consumer electronics – witness the proliferation of wireless chargers at CES 2018 – but it is not just for smartphones and fitness bands. Automakers are working in earnest to offer wireless charging options for their… Read more »
Subaru uses National Instruments’ hardware-in-the-loop tech to simulate road conditions
Subaru is using hardware-in-the-loop (HIL) technology from National Instruments (Nasdaq: NATI) to simulate actual road conditions for EV testing. Traditionally, engineers have conducted vehicle tests using finished cars on test courses or public roads. However weather and fluctuating road surface conditions can make it difficult to conduct reproducible tests. Moreover, according to NI, EVs are… Read more »
Free seminar: Mapping motor efficiency quickly and dynamically with HBM eDrive
Sponsored by HBM The eDrive solution from HBM acts as both a power analyzer and data acquisition system. It has the ability to record ALL signals along the drive train (power source, inverter, torque and speed of a motor, temperatures, CAN signals, strain, vibration, etc.) with a single instrument. This greatly reduces the test complexity and results… Read more »
JCB electric digger gets the job done with no noise and no emissions
In response to customer demands for a yellow machine that can work indoors, underground and close to people in urban areas, UK-based heavy equipment manufacturer JCB has developed its first electric excavator (a “digger” to our British mates). The 19C-1 E-Tec mini-excavator not only delivers zero emissions, it is five times quieter than its diesel-powered… Read more »
SF Motors teases two new EVs, plans to begin production this year
After two years in stealth mode, Santa Clara-based SF Motors recently announced details of two upcoming EVs, the SF5 and the SF7. The SF5 will be available for pre-order by the end of 2018 and is scheduled to hit the road in 2019. The company plans to begin vehicle production this year at its facilities… Read more »
