Stators are inside the engine case. An automotive style alternator is a fully self-contained, externally mounted unit that creates DC current. Another difference between stators and automotive style alternators is the type of magnet uses. Stators use a permanent magnet, and automotive alternators use an electro-magnet.
What is the alternator on a motorcycle called?
The alternator of a motorcycle is more commonly referred to as the “stator.” A stator is considered a less complicated form of an alternator compared to ones found in larger vehicles such as cars. A stator is usually located inside the motorcycle engine and is considered a part of it.
What happens when the stator goes bad?
The most obvious symptoms of a bad motorcycle stator include no spark, weak spark, or intermittent spark (also known as misfiring). Hard starts and a poorly running engine can also be clues that your stator needs to be rebuilt or replaced.
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.
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.
How do you test a motorcycle stator?
Insert each probe into a stator socket. You should read around 0.2 to 0.5 ohms. If you show an open circuit with the “Open” or infinity reading or have higher resistance, then the stator is bad and you must replace it. If these tests all produce positive results, then the stator itself is good.
Can you fix a stator?
Fixing a stator usually involves unwinding and cleaning the original stator core, then rewinding it with a machine or carefully by hand. It starts with looking at the coil heads for damaged or burned wires, then cutting out the protective rubber coating from damaged coils.
What is the function of a stator?
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.
How do you clean a stator?
If you want to clean oil you can use carburator cleaner or similar product like choke cleaner, it would take the oil out and any residual will evaporate or any contact cleaner will work too. Thats on the stator and the aluminum will clean both.
What voltage should a stator put out?
A stator should put out about 70 volts at speed and unregulated.
What is alternator stator?
What is an main stator in an AC alternator? The main stator is the main component part an AC generator (or alternator). It is where the electrical energy is created to supply a load.The main stator is manufactured primarily from wound copper and electrical steel.

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.
What is a stator made of?
The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer.
Does the stator rotate in a motor?
As each change is made, the opposite poles on the stator attract the poles of the rotor. Thus, as the magnetic field of the stator rotates, the rotor is forced to rotate with it. One way to produce a rotating magnetic field in the stator of an AC Motor is to use a three-phase power supply for the stator coils.
How do you test a stator on an alternator?
The stator is the fixed ring inside the alternator. To test the stator windings, with the ohmmeter on the lowest settings, test between each of the eyelets. There should be very low resistance. Test between the eyelets and the stator frame and there should be no connection.
How do I know if my motorcycle alternator is working?
Tests on the alternator/stator coil with the engine off:
- Check the resistance between each of the pins (if there are just two, then the resistance between the two). Use your multimeter on a low resistance scale.
- Check the resistance between the pins and earth (the chassis, or the negative terminal of the battery).
What tests can be performed on a stator?
These additional tests include voltage withstand testing, insulation resistance, polarization index and dc winding resistance measurements, as well as inter turn fault detection. They assess not only the insulation integrity, but also help to identify connection problems and weak points in the stator winding.
How much is a stator?
The Stator is priced at $3,995, though you’ll only need to put down $250 to reserve your own Stator. Just try not to think about how that same $250 deposit could buy you an entire Amazon electric scooter.
Why does my stator keep burning 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.
How many types of stators are there?
Stator of Three Phase Induction Motor
Stator frame. Stator core. Stator winding or field winding.
