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.

Does a stator charge the battery?

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.

What is the difference between an alternator and a stator?

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 alternators excitation system attempts to control the voltage generated in the main stator to a pre-set point.

Does a stator need power?

They do require batteries for power, however, which is a potential drawback in comparison with a motorcycle's alternator system. Because a stator generates its own electricity, motorcycles have systems which are relatively lightweight compared to those in a car or truck.

Can a motorcycle run without a stator?

Without a stator, your motorcycle will not get any spark at all as your battery is not capable of supplying the appropriate power levels to generate a spark. As a result, if your stator is going bad your motorcycle will run very poorly. Eventually, your stator can prevent your motorcycle from starting at all.

Does a stator put out AC or DC?

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.

Will a stator charge at idle?

During an idle, the stator is outputting a small amount of excess amperage that will provide that little charge to the battery, but not enough to do a full complete charge.

What happens when stator goes out?

The stator coil generates the power for the spark plug and other accessories on small engines Without a stator there would be no spark at all, meaning the engine won't run. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Symptoms are often worsened as the engine warms up.

How do I know if my stator is working?

If this stator is in good condition. It should be reading between 0.3. And 0.5 ohms. As you can see

What is the advantage of stator?

Stator laminations reduce eddy current by insulating the core. Thin silicon steel plates are stacked on top of one another around the center, preventing eddy current flow. With the eddy current reduced, the stator core can maintain constant power, keeping your motor running.

Does the stator rotate in an alternator?

The stator is always stationary while the rotor spins, either within it or around it. In this way, the stator can act as the: Field winding (field coil or field magnet), where the stator's rotating magnetic field drives the rotor armature to create motion.

How do you test a stator with a multimeter?

Dynamic Stator Test Set your multimeter dial to AC voltage (VAC) and place the leads into the different stator wire phases. At this point, the engine is switched off and the multimeter should have no reading. Switch on your engine and the multimeter should have a positive reading in the 20s.

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.

Can a stator drain a battery?

The role of the stator is to charge the battery while the motorcycle is on. When a stator has gone bad, that means the motorcycle is running off of battery power alone which will quickly drain it.

What can damage a stator?

Winding damaged due to overload Thermal deterioration of the insulation in all phases of the stator winding typically is caused by load demands exceeding the rating of the motor. Note: Under-voltage and over-voltage (exceeding NEMA standards) will result in the same type of insulation deterioration.

What causes a motorcycle stator to burn out?

A bad diode in a rectifier will dump AC current into a system. The AC current heats up the stator and the heat destroys the insulation and ultimately carbonizes it turning it into a low resistance brick.

Does a motorcycle stator charge the battery?

So, does a motorcycle battery charge while riding? The mechanism of a motorcycle does charge it's own battery while the motorcycle is running. There is a device inside a motorcycle engine, usually referred to as a stator, that charges the motorcycle battery while the motorcycle is on.

Can you repair 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.

How many volts does a stator produce?

For example a 32-amp stator should put out 18 volts AC (VAC) per each 1000-RPM. At 2000 it should be 36 VAC (18x2). At 3000 RPM it should be 54 VAC (18 X 3). Each system has a certain voltage it should produce per 1000 RPM.

How many volts does a stator have?

Tests on the alternator/stator coil with the engine on: 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.
