AI Thread Summary
A user is seeking a motor with specific requirements: a minimum torque of 5.5 mNm, no load speed of 30,000 rpm, power capability of 8.7 watts, and dimensions of 1" in length and 3" in diameter. Suggestions include searching online or consulting NASA, as the rpm requirement is similar to motors used in satellites. The Dremel tool is mentioned as a potential option, capable of reaching up to 50,000 rpm on mains power, though its exact specifications regarding torque and wattage are unknown. The discussion emphasizes the need for a motor that meets these precise criteria for a specific application. Overall, the conversation highlights the challenge of finding a motor that fits these detailed specifications.

Does anyone know of a motor that meets these requirements?

Minimum torque: 5.5 mNm
Minimum no load speed: 30,000rpm
Minimum power capability: 8.7 watts
Maximum length: 1" plus/minus .25"
Maximum diameter: 3"

Thanks!

If no one has a source, why not search online.
 
I hate to sound like Fox Mulder, but have you asked NASA about this? That 30,000 rpm figure seems reminiscent of the stabilization gyros on the early LandSat and KeyHole satellites.

Just thinking out loud... :rolleyes:
 
Oh, nuts! How could I forget the friendly neighbourhood Dremel tool? I've never disassembled one, so I'm not sure about the motor dimensions, and I have no idea as to the torque and wattage, but they spin up to 50,000 rpms on mains or 30,000 on battery power. A bit pricey, but very reasonable for what they can do.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
