Now it's trying to out-Lucid the trendiest EV startup companies with a daring new electric drive motor that breaks some ... use "hairpin" windings—square-section copper wires that slot into ...

Copper rotors exhibit lower losses than aluminum which lets them run cooler and be more efficient. Today the NEMA Premium rating is the highest motor efficiency standard in the world. Spelled out ...

Engineers at ThinGap Motor Technologies, Santa Barbara (www.thingap.com), have come up with an alternative, precision-machined copper sheets. It gives motors a higher copper-packing density and a ...

The magnets are on the conventional motor shaft and the copper windings of the armature are fixed and surround the shaft. Instead of brushes and a commutator, a small circuit board coordinates the ...

Alternative motor technologies can often present a new and increased demand for copper. However, this trend can be offset somewhat by improvements to winding efficiency and copper utilisation that ...

The Copper Development Association (CDA) recently announced its support of the National Electrical Manufacturers Association NEMA Premium Efficient Motor Program, a set of national electric motor ...
