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 »
Huber+Suhner cools the cord with the RADOX high power EV charging system
When it comes to electrical devices, there are two things at the forefront of every consumer’s mind: how long will my battery last, and how long will it take me to charge it? This mentality goes double for EVs. A lot of attention is being put into extending EV battery range, but decreasing EV charging… Read more »
Steady growth of Nordic plug-in sales falters
