Yes, I realised most get them as a package. I was only wondering as somewhere (on their website I think) it said all the stock motors were actually rated to 200V. And everyone has huge praise for these little motors and their performance, so I wondered whether the motors had ever been tested/pushed hard. I know current is limitted through them, wouldn't want to dump loads into one anyway, so the next step was since everyone seems to get roughly 100V/~500A AC into them in most instances, how they'd perform with twice the voltage (and hopefully very little difference in cooling issues) in the same applications. I'd expect near double the performance, probably more as you could increase your gear ratios and maximise benefit of the wider power band.
All speculation, and I'm no electrical engineer (mechanical actually...) but it follows simple logic as far as I can see.
Back to topic though, what do people know of this proposed 144V controller please? Is it a new Curtis controller? Why are Curtis not producing higher voltage controllers already, their software is so widely fplexible they'd still operate at the usual lower voltages no problem and not cost much more from what I can tell.
Also, the improved torque of the AC-75, is this due to the larger area/greater leverage radius of the larger motor, as the controller won't be pushing more amps that we're used to in AC50s etc will it?
