All of the specifications we have can be found on the product page under the specifications tab: free run speed/current, and stall torque/current for both 6 V and 12 V application. However, you can calculate some of the values you are looking for on your own. For example, you can estimate the torque at various speeds by approximating a linear relationship between the stall torque at zero RPM and no torque at the free-run RPM. Also, you can calculate the terminal resistance by plugging the stall current at the specified voltage into Ohm's law.
If you have any additional questions about our products that I can answer, please let me know.
