i bought 2 microgear motors and
i have a questions about it, could you supply the inductance and resistance parameters of this products pololu.com/catalog/product/998
Please do not post questions in unrelated threads. I have split your post off into its own topic and give it a more appropriate subject.
All of the information we have about that motor is available on its product page. If you need to know the inductance, you will need to measure it. However, you can compute the resistance from the stall current, which is approximately 1.6 A at 6 V, giving a resistance of approximately 6/1.6 = 3.8 Ohms (the actual resistance might vary slightly from motor to motor and will also change with coil temperature).
