Building a heavy duty magnet charger
Print Thread Rate Thread. No current will be indicated on the meter if the jumper leads have been improperly connected to the battery. Note the position of the auxiliary pole pieces when charging this magneto. Also my friend is a electronic genuis so he did all the real work.
Gas Engine Magazine brings you: John using the charger at a local New England engine show. Mavneto switch The choice of a knife switch has one big builc.
How to Build and Use a Homemade Magneto Magnet Charger
I shouldn’t have pasted in all the blah-blah text from the web site. If a lathe is not available, coils can be wound by attaching a crank with bolts threaded into each end of the core. Many many years ago I worked at a shop that built these as well as just about magnetic device you coud want. If an ordinary switch is used, always check the ammeter to make sure the current has stopped flowing when the switch is opened.
Order a copy today. Other components, such as the knife switch and terminal board, are mounted to a wood base on the hand truck. Hand truck after modification- ready for mounting the charger. As winding progresses, it will be more and more difficult to prevent the winding from becoming scrambled. Webster Tri Polar Oscillator in position for charging.
Core area must be large enough to saturate the magneto core without maagneto saturated itself. Gas Engine Magazine brings you: In recharging, set the magnet on top of the recharger after its polarity has been determined, and rock the magnet back and forth on its pole edges a number of times. Failure to observe this precaution will result in smoked diodes when the charger is powered up!

To prevent shorts, magnetizre core must be insulated. Re-magnetizing the magnets of a magneto that has become weakened through long use is a simple process.
The windings will heat up quickly when in use; therefore, the switch should be closed for only a few minutes at a time. Search eBay for motorcycle parts magnego following countries. The winding for this recharger is for use on 6 or 12 volt direct current, from automobile storage batteries.

Chargers with sufficient energy have been pictured in GEM, but no construction details were given. Charging magnetos Magnets have the unique property of magnetizing opposite to the polarity of the charging source. Tighten a nut and lock washer over each lug.
Mount the core with terminal end facing the lathe tailstock and run the lathe in reverse to make winding easy to view.
The Square Deal Subscription Program is designed as a paperless transaction with automatic renewals at a preferred low rate. Those units were not sufficiently heavy to charge many magnets while installed on the magneto. An ordinary automotive ammeter reading 50 amperes is sufficient.
What Engine for Clutch Pulley? At this stage, the coils are finished. Then you have to wind two coils, built the rest of the electronics and make the conductors.
Fancier ammeters are available from electronic supply houses or surplus electronics stores. Wind the wire around the electromagnet cores as shown in the illustrations and then wrap tape around the windings, to hold them in place. The other pole should attract the south seeking needle and should bbuild marked ‘S’.
