Can someone please explain the process of how stators work and what they do.<br /><br />I tried to find a website to gather this information but was unsuccessful. If anyone knows of one please let me know.

Re: outboard stators

I'll try! The bottom of the flywheel has either 2 or 4 Magnets on it. On the armature plate, below the flywheel, there is a Stator coil(s). As the flywheel magnets rotates past the Stator, it creates alternating current, which is then sent to the rectifier. The rectifier converts the A/C current to D/C current, which is what you wind up using to charge Batteries and Power other accesories on the boat. Hope this explains it and if I missed something, I'm sure others will let us know!

Re: outboard stators

Hi claden<br /><br />The term "stator" can be used to describe several components. As rickdb1boat says, the winding under the flywheel that produces electricity to charge the battery is called a stator. The windings under the flywheel which charges a capacitor for "ignition" can be called a stators. The windings under the flywheel which generate a signal voltage to fire the ignition module also can be called a stator.<br /><br />The principle they work on is simple "when a conductor is subjected to a moving or changing magnetic field, a voltage is induced within that conductor". The flywheel contains the moving magnets, and the stator is the conductor....<br /><br />Thats why there is confusion...... :)

Re: outboard stators

Schematic wrote a good description of what a stator does. What he didn't mention was that all three parts are often combined into a single unit under the flywheel. That's what makes them so expensive.<br /><br />The is another part of a stator, on certain Johnsons and Evinrudes, that is a power coil to provide voltage for the computer inside the ignition system to operate the Quick-Start feature and to power the infra-red sensors on the 60 degree motors.
