Calculating the dc motor parameters from motor specifications
With so little data it is impossible. You can calculate the torque constant kt (or ki) [Nm/A]. Inertia can't be calculated from electrical properties.
However you could lock the rotor apply a voltage and measure current, stall current. There is a data on the picture, but without a voltage. Probably it's 3V -&gt; R=3/4.7=0.64 Ohm. With this measurement you get resistance.
With a scope you can apply step voltage and measure current, then you get inductance.
