If you think about torque as amps and voltage as speed, it's just like that. Shafts don't (generally) care about how fast you can spin them*, but there is a limit on torque because you will get twist. So for any system where I have a long distance to travel with a shaft, I make sure I don't provide any speed reduction from the drive motor until I reach the destination where the torque is required.

Noooooooooooooooooooooooooooooooooooooooooooooooo!!!!
Electrons!! voltage!! phase!! current!! It's all evil!
MAKE IT STOP!!!!
I'll stick with the torque/speed PHYSICAL definition thank you... at least those
things you can see and touch to fully understand. The electrical stuff - you
can't see it, so the only way to be sure is to use your tongue.
:D

There's a reason why I'm a mechanical not an electrical engineer ;)
