I have looked at quite a few circuits in the last few days: voltage
comparators, frequency to voltage converters, voltage regulators, frequency
counters and magnetic pickups when a thought crossed my mind.
Has anyone used or, know of a circuit that uses the rectifier as a
frequency source instead of a magnetic pickup. Each time the rectifier
conducts positive (or negative for this matter), this is counted for the
time period, converted, and fed to a comparator. Whatever decision is made
is then passed on to the motor speed controller.
I haven't run across one like this, yet. The 3 latter circuits are no
problem. It's the frequency sensing circuit I'm after.
