Hi,
What is a "motor capacitor". The ones i speak of are metalised polypropylene and rated for mains useage.
Why/How are they different from other types of film capacitors?
Is it literally a capacitor which is supposed to just sit across line and neutral of the mains?....upstream of a motor? What kind of motor does it sit upstream of?
Wiki tells of it,
But does not allure to its comparison of ESL and ESR when compared to other types of film capacitors.
..and why it has to be for motors?....eg why not for SMPS?..Eg why not at the output of a Boost PFC SMPS?
