Rewinding the winding is the most frequent and important operation when repairing an engine. Let's look at what it is, when it is needed and what it consists of, so that you understand what you are paying for.
What is rewinding
Rewinding is the replacement of an old, damaged motor winding with a new one. The winding is a coil of insulated copper wire placed in the slots of the stator (or rotor). Over time, the insulation ages, overheats or breaks through, and the entire winding has to be replaced.
When rewinding is needed
- Breakdown of the winding insulation to the housing.
- Interturn short circuit.
- Breakage of the winding.
- Combustion after overload or phase loss.
- Strong humidification that cannot be eliminated drying.
How the process works
- Disassembling the engine and removing the old winding.
- Cleaning the slots and inspecting the stator iron.
- Winding new coils with wire of the required cross-section.
- Laying the winding in the grooves, connecting and banding.
- Varnish impregnationand oven drying.
- Assembly and acceptance testing.
Rewinding or replacing the motor
In most cases, rewinding is 2-4 times cheaper than a new motor. A replacement is chosen only if the stator iron is damaged or the machine is outdated. The quality of rewinding is determined by the resource - the class of the wire, impregnation and testing are important.
