Jonathan,

I was previously under the impression that AC servos had the highest power density, but after seeing this (and your new X3 thread), my entire world is a lie!
Are you able to point me in the right direction to learn more about this sort of motor? I'm unable to find anything useful on them.

Also, I have a few questions you may be able to help me with:
- Why don't I see these sort of motors replacing spindles?
- Why don't I see these motors in non-hobby applications?

As a final year Mechatronic student (in Australia), this project, and your abilities absolutely dazzle me. I thought I was good, but you are in an entirely separate universe...


Love your work.


Lindsay
