How Does a Briggs & Stratton Electric Starter Bullwork?
Briggs & Stratton has recently equipped push mowers with electric starters to facilitate the somewhat rigorous starting procedure. Larger Hay-maker engines, enjoy those in riding mowers, enjoy been fitted with electric starters for decades. All electric starter motors handwriting some sample of invent that are required for flywheel engagement and engine rotation.
Starter Housing
The starter Engine housing is primarily a short, squat tube. Magnets are affixed to the inside wall of the housing, and the starter shaft is suspended in between the magnets. The starter shaft is held in country by bearings in the location plates of the housing. One borderline of the shaft reaches on ice the housing bound cap nearest the engine flywheel. This cusp of the starter shaft engages the flywheel and turns the engine over.
The Shaft
The resulting reaction spins the armature. As the armature spins it maintains electrical connexion on ice contacts, or "brushes," that propel on a plenty of the armature.
The Starter Drive
As the starter shaft spins the manage gear engages the flywheel ring gear, and turns the engine.Inside the housing, the starter shaft is wound with wires and is called the armature. The armature is energized when the ignition switch is turned to the "alpha" position, even adore in a van. A 12-volt lead-acid battery provides the capacity and this power disrupts the Attractive fields.Once the engine starts, the flywheel telephone gear velocity quickly surpasses the starter drive gear celerity. A one-way clutch, or "sprag," allows the drive gear to free-wheel when spun by the engine call gear. Surface tensions relax, and the operate gear retracts with the relieve of a give back spring.
Engagements
Two methods are used to build the starter drive gear engage the engine flywheel gear. Centrifugal force created by the starter shaft turning speed is used to "sling" the gear forward against return spring pressure. The torque produced keeps the gears engaged until the engine speed overtakes the starter gear speed. Solenoids are used to achieve gear engagement through electro-magnetic induction. Mechanical action created by energizing the solenoid forces the starter drive gear forward.
