Reply To: Recharge Magnets on Fly Wheel

[foot_doctor]

This is super. Data gathering. Have you established a consatnt distance from the magnet’s center to measure the strength from? Most flywheel magnetos have their magnets closely spaced, and adjacent magnets can affect the magnetic field of one another if measured at too great a distance. A thickness of index card might be a good constant, and it would prevent the measurement probe from having intimate contact with the magnet pole. Does your gaussmeter suggest a standard distance? I’m thrilled to read of your quest. My ex-racing partner, Charlie Erdman worked for GE Medical systems, and the lab he ran had all of the magnet charging equipment we could ever wish for. He recharged the aluminum Bendix-Scintilla rotors with the polarity that produced the negative sparks that we desired. When we set the points at .009″ they consistantly outperformed the Phelon mags, with higher output voltage, faster time rise, and at nearly 1000 rpms higher crankshaft speeds. Charlie’s magnet charging equipment employed a great lot of capacitors that once charged, were discharged thru the coils of the charging units. Several thousand amps were said to have been released thru the coils for an instant, and Charlie told us that it created an outlandish bang when the button was pushed. My Stevens unit seems to require about 3 seconds of on time to fully charge the magnets. It’s way kool what you’re doing. Thanks from all of us. Knowledge is power. Cheers. R.T.
