Unclear properties of DC motor

  1. Oct 17, 2012 #1
    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.


    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!
