Calculating Motor Mass for Desired Torque

[melo_chip]

Assistance Please!

I'm sorry if this in the wrong section but I'm rather desperate

How do you figure out the mass of a motor to have a specefic torque?

I'd start by looking at datasheets for the motors that are close to what I want. The lighter ones that make the required torque will be more expensive, because they will use higher quality magnets.

You can probably plot a chart of weight versus torque, based on some datasheets at manufacturers' websites, and based on what kind of magnets they use.
