Are they saying that their motor has bronze winding?
In General, Motor winding is made up of copper. (Few cheaper motors has Aluminium). was wondering whether i misunderstood the statement or they are actually using bronze wires for motor winding.
I think it is a nice marketing way of saying they use copper-tin alloy. The “Pure” composition of Bronze is 88% Copper, 12% Tin, if we can consider that pure ;).
Very much doubt it’s bronze. Probably copper. Especially with a little hub motor you need to keep the I2R loses(copper losses) low and you’d need a good conductor like copper
Silver is the best. Less resistance. less increase of resistance with heat. Better thermal transfer and ability to conduct away heat. Graphene would be the only thing better if it ever becomes available. If it becomes easier to make…the world and motors especially will change drastically
You are right.
Why is gold so expensive then? Copper should be more expensive in my eyes, what can you do with gold that makes it so expensive? Just an equivalent for money?
I know a guy/company working on something like this. Not too far from now that will be doable but manufacturing in large quantities safely and economically is quite a challenge
