How to characterize the DC_PM motor?

[tcad]

Hi guys,

I want to do some simulation on the application of the DC_PM motor, now I got a datasheet of the DC_PM motor, it gives out the curves of speed vs. torque, current vs. torque, and power vs. torque. but it doesn't give me the parameters the simulator required, such as the armature winding inductance, armature winding resistance, motor inertia, torque constant, back_emf conatant , number of the poles and motor damping constant. How can I get these parameters from the three curves or other infomation?

Thanks for you help
