Non-standard laminations for electromechanical repairs
Repairing electric motors often requires tailor-made components not available in standard catalogues.
Nestech is the ideal partner for the rapid and accurate manufacturing of single laminations and complete core stacks for the rehabilitation of electric motors, generators and transformers, even those of old generation or non-standard. Our repair services and solutions extend the operating life of your equipment and reduce overall repair costs.
We guarantee:
- Quick and clear answers
- Answers and quotes in very short times
- Availability to handle emergencies or non-standard requests
- Consulting to optimize materials and technologies according to the required performances
Our service is ideal for:
Electromechanical SERVICE and MAINTENANCE
centers
SPECIALIZED
WORKSHOPS
in rewinding and retrofitting
R&D
DEPARTMENTS
for prototype testing or reverse engineering
What we do:
- Single laminations according to drawing or sample
- Custom-made stator and rotor core stacks
- Reproduction obsolete geometries
- Precision machining: laser cutting, assembling, stacking, bonding, drilling, grinding, heat treatment, windings
- Quality checks according to high standards.
WHY NESTECHBenefits:
- 20 years of experience
- High precision laser cutting even on small quantities
- No minimum order
- Fast delivery times
- Large stock of electrical steel available
- Technical assistance for development, adaptation and engineering
- Support even in the absence of a drawing: we work from physical samples
MANUFACTURING HARD-TO-FIND COMPONENTSReverse engineering:
When an electrical component is out of production or its technical drawing is no longer available, we can apply the reverse engineering: starting from a physical sample, we make a 2D C.M.M. scanning to reproduce the geometry , therefore we are able to replicate single laminations and complete core stacks, even for outdated or anyway special electric motors and generators. It is an ideal solution for urgent repairs and to give new life to equipment that would otherwise be completely replaced.
Advantages of reverse engineering:
- It allows to extend the life time of the electric machines
- It reduces costs compared to complete replacement
- It is essential in sectors where spare parts are no longer available
Support and assistance
Every repair is a unique case. For this reason, at Nestech we offer a dedicated technical support service at every stage of the process: from the initial analysis to the delivery of the component.
We support the customer to understand the requirements, reproduce complex geometries even the drawing is missing and propose functional solutions even for dated or out of production electric machines.
We ensure:
- Quick and clear answers
- Quick customized quotes
- Consulting to optimize materials and technologies according to the required performances

FAQ - Frequent Ask Questions
1. Can I send just a sample without a drawing?
Yes, we often work from physical samples when drawings are missing. We analyze the geometry through direct measurements or scanning and propose the most suitable solution. This approach, based on reverse engineering, is very useful in cases of repairs, out-of-production spare parts or customized machines.
2. What is the minimum order quantity?
We do not have a minimum order, we can produce single pieces.
3. What are the delivery times for an emergency?
Emergencies can be delivered within 2 weeks.
4. How do you manage damaged or deformed laminations?
There is no way to repair laminations, they need to be reproduced.
5. What are the risks of inefficiency if the laminations are not correct?
If the laminations are not geometrically correct, damage to the insulation can occur and also short circuits between the laminations themselves, resulting in overheating and loss of efficiency of the motor.
