Yes. THis is filler.Nicksan said:With a ammeter in series with the motor and battery? I think thats how I did it a long time ago.

It is a Mocrosoft Power Point Presentation. The good news is that you can find free, downloadable Power Point Viewers like this one:Nicksan said:Ive googled and yahoo`ed and searched here. I found one link, but its in some strange, proprietary format I cannot read. PPT whatever that is.

Aren't DC impedance and resistance the same? When you measure the resistance you are applying a voltage and measuring the current with the motor stationary. The magnitude of the applied voltage is irrelevant.dknguyen said:DOes that resistance correspond to stall impedance?
DC impedance and resistance are the same. WHat I meant was does the resistance measured represent the impedance of the motor at stall? As in can the stall current be calculated from it. WHich is a bit strange in itself since that would mean the voltage you use determines the stall current (it may, I'm not quite sure.) I was always under the impression that a DC motor's current is representative of torque independent of the voltage being applied.Pommie said:Aren't DC impedance and resistance the same?
