A DC motor on starting and stopping, the back emf is very large even it is in a very short period.
Motor supply is from a rectified 220Vac@50Hz without filtering capacitor. I would like to know, is there any filter (R,C) to eliminate this back EMF? If i place a mono-capacitor in between two motor terminal, will the result is become better and reduce some back emf from motor?
If so, what capacitance is needed?
