products offers magneto magnetizer products. About 16% of these are mobile phone bags & cases, 7% are magnetic materials, and 5% are. “Could you send plans and drawings for the magneto charger in your article?” This was the most frequent inquiry I had after my November GEM article on . I would like to build a magnet charger like the one John Rex wrote in the January I have been a full time Magneto Restorer/Repairman for quite a number of.

I would like to build a magnet charger like the one John Rex wrote in the January G. How is the magnetzier of a magnet measured9 Gaussmeters are used to measure the magnetic field density at the surface of the magnet. When the button is subsequently released, the capacitor is discharged through the core winding. Two people are required, one to operate the lathe clutch, while the second layers wire onto the core with gloved hands.

Building a heavy duty magnet charger

We use two different types of magnetiser for charging the magnets of rotating-coil magnetos: Thanks and you all have a Happy New Year! Some steels have higher permeability than others. Rex’s charger is 20, ampere turns.

The ammeter shown, unlike automotive ammeters, requires the use of an external magneyo for operation. The internal magnetiser can be used for most jobs, and we prefer it because it is so efficient, effective and quick and easy to use. Maneto result was a set of cooked coils. The charger plans from the GEM are great, but I’m afraid it would pull my fillings out of my teeth!

The steel for the core is CRvery common. Additional time does nothing but drain the battery. In the photo above, it is shown with an RB M1 magneto that has an armature diameter of just under 2″, slightly too small for our smaller internal magnetiser core.

Chargers with sufficient energy have been pictured in GEM, but no construction details magento given. It is used for magnetizing the magnet circuit kagneto high-power basetone loudspeakers and high pitch loudspeakers. It’s important to state that increasing charger size ,agneto the point where magnet saturation occurs does not improve magneto performance there’s no harm either. It can charge most mags without dismantling. By comparison with the internal magnetiser, the magnetic path length through the external magnetiser externally of the magneto from one side of the magneto to the other is many times longer.

What Engine for Clutch Pulley? Contact For Free Shipping. Arc suppressor diodes The purpose of arc suppressor diodes is to reduce the high voltage arc produced by the coils when the switch is opened. Hi Folks, this is not meant to be rain on anyone’s parade, but Magnetiaer feel it is necessary to point out a small fact about Magnet Chargers.

The actual mabneto is started by scraping off a half inch of insulation and poking the wire through the start hole in the insulating end washer and soldering it to a lug on the terminal marked ‘1’.

Some people are fortunate to be living in places where these supplies are more common than here in the small city boondocks.


Magnet Charger

Additional shaped pole pieces are useful for charging flywheels, rotors, etc. Magnet wire is available from motor rewinding shops, transformer shops and suppliers specializing in magnet wire.

To protect the coils from damage, I wound several strips of fiberglass cloth and string over the entire coil and painted them with polyester resin. Magnrto procedures were used in the old days because many chargers were inadequate and magnetic theory was not well understood. With all credit to Allan Hurst assuming he was the magheto to conceive of the ‘internal’ magnetiser for rotating-coil magnetosits great advantages are: Could I get samples9 Yes, you will get samples shortly if there are materials in stock.

Brightspark Magnetos – Magnetisers

Russ, my question is what do you ask for? Traded a dozen donuts to the wrecking crew for the switch. Thank you for your comments.

Any help or ideas will be very much appreciated. An identical washer without terminals is epoxied to the other end of each pole piece. 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.

This charger will super-saturate any magnet or magnetic material in 3. The problem with many of these small projects is finding the right materials.

Note the automobile battery for power and a compass for checking magneto polarity before charging.
