@renderrob Hello

So the motor that he is using is a treadmill motor and inside the treadmill there is an integrated motor controller that he used in his previous movie. it can be ran by connecting a pot to the controller terminals.

What kind of accuracy do you get? Got a web page?

[chueffer]

Does the motor lose torque at low revs ?

[renderrob]

omg, I have one of those motors already (same exact body). Any info on the motor controller? Does it vary speed simply by voltage?

[trein45]

What's th highest RPM that machine can have?

[douro20]

These motors can be had from various surplus shops; they are made by United Technologies.

So, how much did it cost and how accurat is it? what is the repeatability?

Mount it at a 30 degree angle an it would run like a Mori Seiki

Nice, same motor I plan on using to convert my 9x20 to DC varispeed.

I love how all the real machinists equate treadmill motor to Burdens :-)

How are you controlling your motor?
