Discussion Overview

The discussion revolves around finding a motor that meets specific technical requirements, including torque, speed, power capability, and dimensional constraints. The scope includes practical applications and potential sources for such a motor.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about a motor with a minimum torque of 5.5 mNm, a no-load speed of at least 30,000 rpm, a power capability of 8.7 watts, and specific dimensional limits.
  • Another participant suggests searching online for potential sources if no one has immediate recommendations.
  • A different participant humorously references NASA, noting that the specified speed might relate to stabilization gyros used in early satellites.
  • A later reply mentions the Dremel tool as a possible option, highlighting its high RPM capabilities but expressing uncertainty about its torque and wattage specifications.

Areas of Agreement / Disagreement

Participants do not reach a consensus on a specific motor that meets the requirements, and multiple suggestions and ideas are presented without agreement on a definitive solution.

Contextual Notes

Some limitations include the lack of detailed specifications for suggested motors, such as the Dremel tool, and the uncertainty regarding whether the proposed options meet all the stated requirements.

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.
