mahnetizer After charging, the polarity can be verified by the use of a bow. This is a plain book that offers clues to folks who are trying to solve a very particular problem. Additional shaped pole pieces are useful for charging flywheels, rotors, etc. This will insure winding direction and poles match those in the photos. You can actually see if it’s open or closed. Magnetomotive force product of amps times turns of wire must be large enough to bring magneto magnets to saturation.
Unless this is done, they will lose their magnetism rapidly. Tighten a nut and lock washer over each lug.

The result was a set of cooked coils. Gas Engine Magazine is your best source for tractor and stationary gas engine information. Showing of 12 reviews. Description The charger described here is designed to operate from a volt automotive battery, has a core area of seven square inches and provides 20, ampere turns of energy. An identical buid without terminals is epoxied to the other end of each pole piece.

This booklet is a great help to novices who are fumbling with a recalcitrant magneto. Hi, My friend and I just did this.
Webster Tri Polar Oscillator in position for charging. This is adequate from a magnetic standpoint and is readily available from steel supply yards.
It is sufficient to saturate and charge most fully assembled magnetos used on antique engines. If the wiring and winding have been done as indicated the north and south poles should be as shown in the figures. If an ordinary switch is used, always check the ammeter to make sure the current has stopped flowing when the switch is opened. Fancier ammeters are available from electronic supply houses or surplus electronics stores.
Then lay it on its side with its poles away from you and extending just beyond the far edges of the electromagnet poles. Do not use tool steels, cast iron or other high carbon steels, they have too much magnetic loss.
Print Thread Rate Thread. This takes only a few seconds. If you have a source of scrap iron, machine shop facilities and can come up with some surplus magnet wire, the costs can be drastically reduced. Amazon Renewed Refurbished products with a warranty.
Build a Magneto Magnetizer SOLD OUT!
No idea if this of any use to anyone or even if it works but when I came across the link by chance I thought I magnetizef pass it along to those REAL DIY’ers out there that tinker with the real magical parts! Chargers have been described in the following issues: This article has drawings and instructions for making and using that charger. It is important that unlike poles of the magneto magnets and of the electro magnets be brought together; i. The actual winding is started by scraping off a half inch of insulation and poking the wire through the start hole in the insulating end washer and jagneto it to a lug on the terminal marked ‘1’.
Plus our Flywheel Forum column helps answer your engine inquiries! At this stage, the coils are finished.

Without a healthy magmeto, the engine won’t run. If a lathe is not available, coils can be wound by attaching a crank with bolts threaded into each end of the core. The keeper should remain in place until the magnet is reassembled on the magneto. Once the magneto is positioned, charging is accomplished by closing the switch and letting the current build to a maximum as indicated on the ammeter.
A compass needle points north, because the end of the needle is charged south.
