How to address the servo drive for motor
I don't understand why when we connect high voltage source in DC to electronic motor , we must add capacitor and resistor in parallel ? (I know that we use capacitor because we want to absorb the current that in the first second electronic motor in opposed with current course produce. ) what are the feature of Resistor and in such situation ?
