Why Electric Chainsaws Burn Out Armatures98

Electric chainsaws are powerful tools that can make quick work of cutting through wood. However, one of the most common problems with electric chainsaws is that they can burn out their armatures. This can be a frustrating and expensive problem, but it is one that can be avoided by understanding the causes of armature burnout and taking steps to prevent it.

What is an Armature?

The armature is the rotating part of an electric motor. It is made up of a series of coils of wire that are wrapped around a metal core. When electricity flows through the coils, it creates a magnetic field. This magnetic field interacts with the magnetic field of the stator, which is the stationary part of the motor. The interaction between the two magnetic fields causes the armature to rotate.

Why Do Armatures Burn Out?

There are several reasons why armatures can burn out. The most common causes include:* Overheating: Armatures can overheat if they are used too hard or for too long. This can cause the insulation on the coils to break down, which can lead to a short circuit.
* Overloading: Armatures can also burn out if they are overloaded. This can occur if the chainsaw is used to cut through wood that is too thick or too hard.
* Lack of lubrication: Armatures need to be lubricated in order to reduce friction and wear. If the armature is not properly lubricated, it can overheat and burn out.
* Electrical problems: Armatures can also burn out if there is a problem with the electrical system of the chainsaw. This can include problems with the wiring, the switch, or the motor.

How to Prevent Armature Burnout

There are several things you can do to prevent armature burnout, including:* Use the chainsaw correctly: Make sure to use the chainsaw according to the manufacturer's instructions. This includes using the correct blade for the type of wood you are cutting and not overloading the chainsaw.
* Keep the chainsaw clean: Clean the chainsaw regularly to remove sawdust and other debris. This will help to prevent the armature from overheating.
* Lubricate the chainsaw: Lubricate the chainsaw according to the manufacturer's instructions. This will help to reduce friction and wear on the armature.
* Inspect the electrical system: Have the electrical system of the chainsaw inspected regularly by a qualified electrician. This will help to identify any problems that could lead to armature burnout.

Conclusion

Armature burnout is a common problem with electric chainsaws, but it can be avoided by understanding the causes of armature burnout and taking steps to prevent it. By following the tips in this article, you can help to extend the life of your chainsaw and avoid costly repairs.
