Hello all, I have a question regarding the polarity of the magnets on the flywheel of my 97 sport jet 175. In order to adjust the strength, the magnet is divided into two co-axial nested rings, where the inner ring is fixed and the outer ring can be rotated. You never hit a flywheel directly with a hammer or drop it on the floor, unfortunately you are looking at the only thing on the bike you cannot test. When discrete ferromagnetic objects—such as gear teeth, turbine rotor blades, slotted discs, or shafts with keyways—are passed through the probe's magnetic field, the flux density is modulated. As mentioned, magnet M2 is essentially a duplicate of magnet M1 except that the north pole (N) of M2 is the leading pole; and, accordingly, the waveform of FIG. So the center lobe is just part of the skeleton of the contraption.

Improper positioning of the magnets will affect the flywheel balance and can damage the engine. nut, flywheel and flywheel key. The flywheel is attached to the engine crankshaft. The plug will fire just as the rear edge of the magnet clears the sensor. The flywheels look the same, but if you run a test magnet along the inner magnets you can see that the X flywheel magnets are reversed in polarity. The forces between the magnets make them directly implementable for designing permanent magnet thrust. I do not want to reverse its polarity so that I must take it down to zero and then build it up in the reverse polarity. Please note this flywheel has 18 magnets 9 of which are different than the other 9 so if you have more than 3 broken magnets you will have to purchase more magnets. Exposed materials.

It made little sense to waste that energy every time the magnetic field was allowed to decay. It's the CHANGE in magnetic fields as the flywheel spins that actually creates the pulse that fires the plug. And put it so every other one is opposite as you reattach them. See Figure 7. Place the flywheel on the bench, magnets facing up. If any part of the flywheel is damaged, it can cause poor engine performance. Then use a piece of ferrous metal to pass in front and measure the volt drop across the resistor. The more times it changes from north to south polarity ,the better output for a charge. Magnetic sensors work on the principle of induction, which states that a metal object or magnet when placed across a coil winding will induce a current on that coil. So I need a little help to do this If anybody had a known to be good Ducati flywheel, could you look to see if the single little molded part of the magnets lines up with the line on the flywheel used to correctly position the crank?.
