Here Are What May Be Killing Your Coil & Rotor (Amateur) & How To Fix Them

Armature (Rotor) and Coil (Stator) | Img src @Amazon.nl

I recently bought a brand new generator and in the space of a month or so, it generated coil and rotor issues.

You may have faced or be facing a similar issue and wondering what could be the problem. This could be worrisome especially with new generators. 

What exactly are the coil and armature?

The coil is the electrical coil which in your generator. This part is static and does not move during the operation of the generator. The rotor rotates within the coil, generating electricity, thereby, converting mechanical energy to electrical energy. All these happen in a complex magnetic field to produce the electricity that your generator set generates to power your electrical appliances.

The layman refers to the rotor as amateur. This is the popular term it's know by. It is the part that rotates within the coil to produce electric current.

You may be wondering why your generator coil (stator) and or rotor keeps burning or dying over and over again.

When my rotor and coil became unusable, I recoiled them, but after a while, they ceased working again, until I had to replace them both. This was due to the fact that the generator came with an aluminium coil which was generating excessive heat during operation, thereby, causing excessive expansions within the electrical housing, and causing damages. This coil type was not suitable for my electrical loads.

If your coil and or rotor keep(s) dying or burning, here are some things that may be causing this issue:

1. The Generator May be Carrying More Load than it Could: If your generating set is used for carrying more loads than its power can suffice, it may struggle to overcome the load resistance. This in turn, generates heat within the coil and rotor. Too much accumulation of heat within the housing of these elements could cause the wires of the coil and rotor to melt or burn over time.

2. Cheap Materials May Have been Used for Your Rotor and Coil: In order to save cost, manufacturers can result to using cheaper materials to manufacture the coil and rotor (armature) materials. For instance copper coils are better over all than aluminium coils. This is because copper is a better conductor of heat and electricity than aluminium. Aluminium coils easily heat up with time. If the excess heat is not dissipated, they can easily melt or burn out. This may also be the reason why your rotor or armature casing keeps breaking and the rotor bearing keeps wearing out. If you are experiencing this, check the type of coil that came with your generator. If you are using it to power heavy loads, then change the coil to a copper coil if it came with an aluminium coil.

3. There May be Bridging  (Contacting) Wires: It is also possible that electrical wires within the electrical compartment of your generator may be bridging, or the wires conducting electricity from generator to your house, room or office may be bridging. If the wire plug keeps burning, it is a pointer to an excessive heating. If you see smoke oozing out from any part of the wire, it is an indication of bridging wires. Sometimes, the wires may be bridging where you can not visibly see with your eyes. If that's the case, take an AVOmeter/multimeter and set it to measure resistance. If the reading indicates full resistance when the positive and negative terminals are measured, it indicates bridging wires. This is because these two are not supposed to touch each other. It is therefore, a bridge (contact) that results in the full resistance scale reading. If you have discovered the wires to be bridging, then you need to disconnect them. The bridge could be happening within the plug head (the one you connect to your generator. It is a very possible culprit) or within the transmitting wire itself, or within some sockets or extensions at the receiving end. Whichever be the case, you need to decipher and resolve it to avoid further burning of the coil and rotor (armature)

Hope this helps you to fix the burning or dying rotor (armature) and coil (stator) in your generator. If you found this post helpful, don't forget to share it with others who may also find it helpful. Click/tap the share buttons below this post to share.
