polorized capcitor charging
Hi. Thank again for valuable replies and concernes for safety.I guess i did not fully explain use in my 2nd post(#23). Am building a magneto charger to recharge tired north and south alnico magnets contained in a 1 1/2 inch dia.rotating armature as used in a magneto. For charging will be using 1 north and 1 south electromagnetic(solinoid type) coils . Armature will be solidly retained between 2 coils by machined 1 1/2 inch bolted down cross bars. Fly back diodes will be used. A bleed down resistor will be used via a normaly open switch. Switch closed after charging magnets,then reopened for next cycle.After ac power is shut off,fully charged capcitator, via a 2nd switch,Will discharge instantly into 2 copper wound coils with 1.1/2 mild steel cores.AS am using many turns and each coil is 5 inch long ,hopfuly will be able to use smaller cap,but still have option of larger cap if more gauss is needed.YES,there are chargers out there but they will only charge older horseshoe magnets,not alnico.Yes, there are still a few places i could send them to at reasonable cost.Do not wish to,am building my own .Sorry for such a long post,Yours Ben. PS To moderator.If you were a doctor and i a terminil patient,would you pull the plug quicker because of my lack of education?? Hope ya got a sense of humor,Ben.
