I have a 27.5 vdc circuit that will control a 18v motor and keep it at a constant speed when different loads are applyed to the motor
problen is one of the caps are labeled as fallows
10 percent,MF,1.0nF,NI. the 10 percent I get,the metal film i get,1.0 nF get that too. what i don't get is the NI. does NI mean niobiun oxide, if so are these caps metal film.
I'm with KI6RWX, Non Inductive. The circuit that it is in is a saw-tooth oscillator which generates a puesdo-triangle wave which is compared to the a slowly-varying voltage level proportional to the motor's speed to produce the pulse-width modulation which switches the motor on-off.
