What are stator magnets?
The stator is in the stationary electrical component. It consists of a group of individual electro-magnets arranged in such a way that they form a hollow cylinder, with one pole of each magnet facing toward the center of the group. The term, “stator” is derived from the word stationary.
Why are there magnets built into the flywheel?
FLYWHEEL MAGNET FOR IGNITION A permanent magnet is mounted on the flywheel. As the flywheel rotates, the magnet passes the ignition coil inducing a voltage in it (see Photo 1). The coil provides the spark to the spark plug.
Is a stator a permanent magnet?
The stator of these devices may be either a permanent magnet or an electromagnet. Where the stator is an electromagnet, the coil which energizes it is known as the field coil or field winding. The coil can be either iron core or aluminum.
What does a flywheel stator do?
While the stator is stationary, the ATV’s flywheel is attached to the crankshaft and spins around the stator in unison with the engine’s RPM speed. These magnets generate electricity when they pass over the stator’s wire coils. The ATV’s flywheel also communicates with the pick-up coil.
Can magnets on flywheel go bad?
Yes, a flywheel can lose it’s magnetism. If left on a metal table or allowed to collect metal hardware while sitting they can lose some of their magnetism. If you have the equipment, rotors and flywheels can be recharged.
How big are the magnets on a flywheel?
The original ceramic magnets are .3 inches thick. The disk magnets have a flat surface that is mounted on the curved inside diameter of the flywheel so there being a little thinner provides a comfortable mechanical clearance. Also, since the Rear Earth magnets are stronger, the increased air gap helps off set this.
How is the field strength of a flywheel measured?
The field strength is the peak at the pole and in measured in Gauss. 7.2 This flywheel is typical of the older H or V 50, 60, and 70 series engines. The South pole is on the left and North pole is on the right. 7.3 This is the typical Tecumseh ignition the is under the flywheel.
Where are the flywheel magnets on a Tecumseh engine?
7.3 This is the typical Tecumseh ignition the is under the flywheel. 7.4 This flywheel, part number 610758, is from a Tecumseh HH120 engine with an under the flywheel Solid State Ignition system, 610759. The other parts of this ignition are shown on the pages titled Pulse Transformer and Solid State ignition.
Where are the flywheels on a hh120 engine?
7.4 This flywheel, part number 610758, is from a Tecumseh HH120 engine with an under the flywheel Solid State Ignition system, 610759. The other parts of this ignition are shown on the pages titled Pulse Transformer and Solid State ignition.
