Calculate the speed of the flywheel for my drone motor

Click For Summary

Discussion Overview

The discussion centers around calculating the rotational speed of a flywheel attached to a drone motor with propellers. Participants explore the relationship between the motor's RPM and the flywheel's RPM, considering factors such as the flywheel's diameter and the gearing mechanism involved.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant describes a drone motor with propellers attached to a flywheel and seeks to determine the flywheel's RPM based on the motor's specifications.
  • Another participant questions the initial contributor about the work done so far and the understanding of their own invention.
  • A different participant suggests that if the prototype is built, measuring the speed directly would provide the answer.
  • One participant expresses skepticism about the patent and requests more information about the patent application to clarify the concept being discussed.
  • Another participant proposes that basic gearing calculations could be used to determine the flywheel's RPM based on the motor's RPM and the diameters of the flywheel and propeller drum.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the understanding of the invention or the calculations needed. There are competing views regarding the feasibility and clarity of the proposed setup.

Contextual Notes

Some assumptions about the gearing mechanism and the relationship between the flywheel and propellers remain unresolved. The discussion lacks specific details about the gearing ratios and the exact configuration of the components.

I have drone motor with propellers attached to the top of ring flywheels rim at the edge and the flywheel is 18 inches in diameter and weigh's 2kg.
The drone motor with propellers rpm 5200 and thrust 900 grams.
What rpm will the flywheel be rotating at.

What work have you done so far? What have you found out?

Which tells us exactly nothing in terms of answering your question, so I ask again: what work have you done on answering your question?

If you've built it, why not simply measure the speed?

Can you provide the patent number/country? I have a hard time believing you can patent an invention you don't understand and can't explain. But at least the application should give us more information about what you are trying to do.

If you're powering it with a 5200RPM motor, it should eventually hit 5200RPM, given enough time. I will admit that I'm having a rather hard time envisioning exactly what you're trying to do here though.
 
This looks like basic gearing calculations. Motor is attached to flywheel, which spins propellers.

Let's say propellers are spun from flywheel's edge with belts or gears and they need to spin at 5200rpms in order to generate 900g lift. Simple enough to calculate ratios of 18" flywheel diameter to propeller's gear/drum diameter. Divide propeller's 5200rpms by ratio and that's what you need to spin flywheel to.

FlywheelRPM = 5200rpms / (FlywheelDiameter/PropDrumDiameter)
