What Is the True Torque and RPM of This DC Motor?

[mechapeno]

Hello everyone

For a project I'm currently working on, I need a dc motor which can generate a torque of about 0.1-0.2 Nm (or more) with a rpm of about 120-200.

http://uk.farnell.com/crouzet/82861015/motor-geared-24vdc-430rpm/dp/3115616?Ntt=CROUZET+-+82861015.+-+MOTOR%2C+GEARED%2C+24VDC%2C+430RPM

The geared motor of the above link, (data sheet: http://www.farnell.com/datasheets/30394.pdf) looks promising at first sight, but when you browse some more on farnell.com, you encounter a lot of these 'Crouzet' motors which are priced equally, have the same torque, but different rotational speed.

So, I was wondering: is this 0.5Nm torque the torque the motor delivers as input to the gearbox (so the output torque - after the gearbox has done it's job - is higher/lower) or is this really the applicable torque and rpm for the motor?

Thanks in advance!

When people quote numbers for devices like that, they almost always are the "rated" numbers. Rated usually, but not necessarily means maximum.
