The stator is the coil of wire housed inside the engine case. A magnet on a shaft spins within the stator, creating alternating current (AC). That current travels along fairly heavy gauge wire through the case and into the rectifier/regulator which converts it to DC power, and at a consistent output.
What does a stator do on a motorbike?
A motorcycle “alternator” is more commonly called a “stator” and is accompanied by a regulator/rectifier. To
generate AC power
, the stator works with a rotor, known as the flywheel. The AC power is converted to DC through the rectifier, while the regulator regulates the voltage to the battery.
How do you check a stator on a dirt bike?
How does a stator charge a battery?
What happens if stator is bad?
The stator is the one that is responsible for providing the spark required by the spark plug. When the stator malfunctions, it is no longer able to send out strong enough sparks. As a result,
you end up getting a very weak spark
. This event could be either regular or could happen seldom but sporadically.
How do I know if my stator is working?
Will a stator charge a battery?
An ATV uses what is called a stator system or magneto system to charge its battery
. This is a fairly simple and robust system located on the inside of the ATV’s engine. Any time the engine is running, the stator is continuously generating an electric charge.
Why does a stator burn out?
That
high voltage spike can punch through the enamel insulation in the stator coils and cause them to short out
. This “inductor kick” is how the spark in an ignition coil is generated from 12volts. Not many people realize the spark is created when the current through the coil is switched off.
What causes a stator to fail?
When a stator fails, it is largely due to the
degradation or aging of its insulation through external occurrences and materials being introduced into its system
.
How do you troubleshoot a stator?
How do you fix a stator?
How do you bypass a stator?
Does a stator charge?
The battery would quickly be depleted, though, if not for the star of the charging system show, the stator.
Think of your stator as the piece that makes electricity to keep your battery charged up
to make all that electrical stuff on your bike work.
How does a dirt bike charge its battery?
The alternator creates alternating currents to run the bike and charge the battery
. The regulator/rectifier changes, or rectifies, the alternating current produced by the alternator into direct current so it can be stored in the battery and regulates the amount of current produced to prevent overcharging.
How much voltage does a motorcycle stator put out?
You now can test the voltage between the terminals of the stator coil at 3,000 rpm. Depending on your motorcycle, you should get a reading of anywhere
between 20 and 50 volts
.
Will a bad stator drain a battery?
If you have a bad stator
the battery will be draining everytime you are running the engine
.
How does a stator work?
In an electric motor, the stator provides a magnetic field that drives the rotating armature
; in a generator, the stator converts the rotating magnetic field to electric current. In fluid powered devices, the stator guides the flow of fluid to or from the rotating part of the system.
How do I know if my stator or rectifier is bad?
Key Signs to Look For
First, the diode can burnout and cause the battery to drain. You won’t have any trouble diagnosing the faulty regulator rectifier if the battery is the cause. You’ll note signs right away like
poor starts, fluctuating meter readings, and dimmed headlights
.
How do you test a bike stator?
How many stator windings are there?
Generators for motor vehicles
The stator is fitted with a
three-phase winding
.
How do you check voltage on a stator?
Does a stator rotate?
As the magnetic field of the stator rotates
, due to the effect of the three-phase AC power supply, the induced magnetic field of the rotor is attracted and will follow the rotation. The rotor is connected to the motor shaft, so the shaft rotates and drives the connection load.
Is a stator and magneto the same thing?
The stator and the magneto really can be thought of as the same thing
. Simply put the stator is the stationary, wire wound portion of the power generation system. Magneto is the common name used when describing a permanent magnet to produce alternating current.
Is 14.6 volts too much?
14.8 would start to be a worry (there might be liquid or corrosion on the battery) and 15 volts would be a real concern, but
14.6 is fine
. Less than 14.3 would be a “weak” alternator or regulator. Much less than 14.2 at a fast idle is bad wiring, bad alternator or regulator, or a bad connection or fuse link.
Can you rebuild a stator?
In many cases a new stator is the safest, most cost-effective solution for an electrical system breakdown. Because repairing stators can be an intricate and detail-intensive process,
replacing failed stators with an entirely new part can be a much easier route, depending on the specific motorcycle
.
What is the difference between a stator and an alternator?
A motorcycle stator is a component of the electrical system that, when combined with a rotating magnet, creates AC current. Stators are inside the engine case. An automotive style alternator is a fully self-contained, externally mounted unit that creates DC current.
