Hi,

I’ve purchased the 1093 Micro DC motor.

pololu.com/catalog/product/1093

I am trying to model a DC motor system for PID control of the motor’s speed, and in order to do that I need the following parameters:

- (J) moment of inertia of the rotor

2 .(b) motor viscous friction constant - (Ke) electromotive force constant

4.(Kt) motor torque constant - ® electric resistance
- (L) electric inductance

Can I assume that the electric resistance is 6V/120m- the specs for a free run?

Is the moment of inertia 9 oz-in(0.6 kg-cm) ?

Thank you,

Alex
