DC motor parameters estimation !

hi all,
I need your help, experience, references, or hints on how to estimate the parameters for any DC motor , like these parameters
----------------------------------------------------
These are the motor parameters that are needed:
Motor voltage constant Ke (volts-sec/rad)
Motor torque constant KT (lb-in/amp)
Motor resistance Ra (ohms)
Motor inductance La (Henries)
Motor inertia Jm (lb-in-sec^2)
Load inertia reflected to the motor armature shaft Jload (lb-in-sec^2)
-----------------------------------------------------
because sometimes we find a dc motor from any source and need to make any control project but you need its parameters to work, so if one have any information will be thanks
