    Resetting SCR in this circuit

    I'm trying to reset an SCR.....I know you have to drop the holding current below a certain point, but i cant figure out how to do that. Right now im just cycling the power, but i need to figure a way out to reset it electrically. I built a braking circuit that shorts the motor leads thru a...

    pmdc motor circuit

    I'm currently trying to design a circuit that will regulate the current/voltage go to and leavin an PMDC motor. A 24V PMDC motor turns a rotating cylinder and at certain points the motor then acts as a generator because the cylinder makes the motor run faster. So im trying to design a circuit...
