You may find yourself sometimes wondering how your motorcycle battery works and what keeps it’s life up, especially if you use your motorcycle fairly often.

You may be familiar enough with how a car’s charging system works to wonder if it applies to your motorcycle. How does a motorcycle’s battery charge while it is being ridden? The mechanism of a motorcycle does charge it’s own battery while the motorcycle is running. The stator, which is usually found in a motorcycle’s engine, charges the motorcycle’s battery when the bike is turned on.

I’ve owned many motorcycles throughout my life and have become quite familiar with their charging systems. Too many times I’ve run into issues with my motorcycle batteries which forced me to learn a lot about where their charge comes from. You will need to maintain your motorcycle batteries. This knowledge can save you a lot of trouble down the line.

How the Battery Charges While the Motorcycle Is On

Without a stator, your motorcycle’s power would quickly drain and ultimately be unable to run. The stator on a motorcycle is a bit like the electromagnet Iron Man uses to power his chest. It works in the same way as an alternator for a car.

A motorcycle’s space is limited so the stator is placed inside the engine as a part of it rather than having a separate entity like a car. It is usually located on the side of the engine where you will be able to see it once the engine side cover is removed (each motorcycle is a little different with it’s location).

The functionality of a stator is fairly simple, but it’s important you know how it works; A motorcycle rider who is a skilled one should be familiar with how the machine works.

AC power is generated within a stator by the flywheel rotating around it. The stator is made up of several spokes with copper magnet wires that are coiled around them.

There are also magnets on the flywheel, so when the flywheel spins around the stator and it’s spokes, the two sets of magnets (the stationery ones on the stator and the moving ones on the flywheel) generate the necessary power to the battery that is required for the battery to fully function.

And in other words: it’s an electric motor that provokes an electrical supply to the motorcycle and keeps the battery charged.

Motorbikes are dependent on both the stator as well as the battery. The two components are essential for motorcycle functionality and you cannot have one without another. Modern motorcycles have a special need for stators Because they contain more electrical components than older motorcycles, and so rely more on the stator to generate the electricity.

An identical system was used in the early motorcycles. The magneto is a small, independent system that runs the engine. The magneto created the spark necessary for the spark plug’s ignition to ignite the motorcycle.

Battery charging on motorcycles has come a long way; stators in motorcycles are the best they’ve ever been due to their efficient performance.

The Difference Between an Alternator and a Stator

The functions of an alternator in a car or a motorbike’s stator are very similar. An alternator for a car is composed of many parts. A stator is one of those parts. The car’s alternator is basically the same as the motorcycle’s stator.

A motorcycle’s simple stator has only one component, but an alternator contains many more. A car is obviously more complicated than a motorcycle. An alternator, it would seem, would require more components to keep pace with the more complicated systems in a car.

The alternator in a car was also made to be somewhat accessible and easily replaceable because it’s very common for a car to need an alternator replacement several times throughout the car’s life. Cars are driven more than motorcycles and so the alternators get more mileage.

Because motorcycles are used less frequently, it makes more sense to place the basic system of an alternator (the stator) inside the motorcycle. It is unlikely that an individual will need to replace the alternator as frequently as it is an alternator.

Signs that your sator is not functioning properly

It’s a good rule of thumb to be aware of the symptoms of a bad or malfunctioning stator. The quicker you’re able to identify the problem, the quicker you can fix it and save yourself time and perhaps hundreds of dollars.

These are signs that your stator may be giving you. The biggest sign you’ll notice is that your battery isn’t getting a charge at all.

This is a very obvious sign to observe because your motorcycle will start acting sluggish and lights will start to lose power while it’s running. Your bike may end up slowly and even completely dying because it’s solely relying on the power from the battery; battery power alone isn’t powerful enough to keep a motorcycle running for very long.

You may hear your engine making a whining noise if your stator is faulty.It’s similar to an electric engine being manually turned. You may especially notice this if you aren’t turning the throttle at all and letting your motorcycle coast while on a ride.

Another symptom to be aware of is if your motorcycle struggles entering high RPM’s. Some motorcycles may do okay at lower RPM’s with a bad stator, but once it’s revved higher, the bike will stall simply because the motorcycle doesn’t have the power supply needed by the engine in that sort of state.

There are a few things you can do to confirm that you suspect your stator is going missing.

First, try taking off the side engine cover to expose the stator (be sure to check your owner’s manual to identify the stator’s exact location). Examine the overall condition of your stator. Are there any major changes? “burn” marks? Are the copper wires damaged or frayed? Does anything look missing or out-of-place? Do any of the components seem like they’ve melted together?

A multimeter can also be used to test the voltage of the stator. Locate the stator connector, and unplug it. Turn on the motorcycle. Your multimeter reading should be changed to AC. Check the voltage at the terminal tabs of the stator connector. Each terminal should have a voltage reading that is similar to the other. If you see voltage readings that are different, it is likely that the stator is defective.

What does the Battery do if The Stator Charges It?

Many people wonder if the stator really runs the entire electric show on the bike. If so, what is the purpose of the battery and why is it needed?

Most cases, a dead or insufficient battery will prevent you from starting your motorcycle. The motorbike is started by the stator.

Your motorcycle’s battery provides the power to start your bike. It sends an electricity current to spark plugs that then ignite the engine. After the motorcycle is turned on, the stator kicks into action, generates power, and then recharges the battery. “refills” the battery since the battery used a lot of it’s juice to start up the motorcycle.

A motorcycle battery and a motorcycle stator go hand-in–hand The stator starts the battery and the stator returns the favor.

It can be very frustrating to have electrical problems on a motorcycle. Understanding the workings of electrical components can help you save a lot of frustration. You may soon find yourself an expert on motorcycles.

Similar Questions

Can you clean a staor? A stator can be cleaned. You can clean your motorcycle’s stator with a light lubricant like WD-40. You should not use harsh chemicals or abrasive cleaning products on your stator as they can cause damage.

What happens if a bike battery isn’t working? A motorcycle battery can freeze. It is possible for a motorcycle battery to freeze if it is discharging. This depends on how much charge remains. A fully charged battery is much more resilient to cold weather and will not freeze until it gets to about – 75 or -76 degrees fahrenheit. For more information, click here.
