Motor manufacturing: Tempel builds state-of-the-art factories to meet automaker’s requirements

Stamping precision parts for automotive-grade motor manufacturing The demands of the automotive industry are unlike any other. Carmakers require that their suppliers deliver millions of parts with incredibly tight tolerances that will not fail after a decade of daily use. The companies that manufacture parts for ICEs have grown increasingly sophisticated and disciplined in the… Read more »

Regenerative braking: A closer look at the methods and limits of regen

All motors are generators, the old saying goes, with the caveat that few types are equally good at both modes of operation, and some are downright awful as generators (a classic example being the single-phase shaded pole induction type, used in myriad small appliances the world over). Fortunately, both types of AC motor commonly used… Read more »

Charge like A supercap, store like a battery: ZapGo’s carbon-ion technology

Imagine an EV that could add 300 miles of range with a 5-minute charge – roughly the same amount of time it takes to refuel an ICE vehicle. Many companies are working on technologies to enable faster charging, which would be a huge win for EV adoption. ZapGo, based in Oxford, UK and Charlotte, North… Read more »

Top circuit protection requirements to consider when designing an automotive battery pack

Littelfuse helps the auto industry navigate new electrical engineering challenges When engineers design a battery pack, they tend to focus first on its core functionality and value proposition. For a high-end energy storage device, those core attributes are typically things like total pack energy density, cost minimization, packaging efficiency, peak power and state-of-the-art thermal management….

A closer look at film capacitors

Plastic film capacitors relentlessly continue to take over many of the duties in EV power electronics that were once performed by the venerable aluminum electrolytic type, mainly because film capacitors exhibit much lower losses and have a much longer operational lifespan, especially at ambient temperatures in the 75-85° C range. The tradeoff is that film… Read more »

Tecnomatic helps automakers design specialty assembly processes for advanced stator technologies

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 »
