    Hello everyone that has a good understanding of electrical engineering.

    Why is this technic not used as it would make the motor smaller and could have much more tight windings. My thought is not to have someone assembly this by hand, rather print the sheets with the copper in and stacking them by machine. You would have a motor with more exact field strength as windings don't vary in distance.

    The efficiency of the motor might just be too good already that little better wouldn't change specs a whole lot. Might be better to have lighter wheels to reduce spinning mass.

    Im I just away on a thinking spree?

    Is your question why doesn't Tesla use flat copper plate coils (like the magnet video) and instead uses windings of copper wire?

    I'm thinking that perhaps the labor involved would be prohibitive. I don't know many people as patient as that poor coil builder. Cool video though. I used to drop neodymium magnets through copper pipe to watch my nephews' jaws drop and ask HOW HOW!

    Not sure exactly what you're asking, but the Tesla motor is already ridiculously tiny. Its a 400hp motor the size of a milk jug. Its also probably already extremely efficient. Any dollars spent decreasing the motors weight or increasing its efficiency would be far better spent in another area.

    Also keep in mind that most of the limiting factors on power come from either the battery or the inverter, not the motor itself.

    yes this is my question. But surely you could automate the process. Like you stated probably its more effective to improve other areas.
