From physical sample to certified magnetic reconstruction
When a component is out of production or technical documentation is missing, we apply reverse engineering process that combines dimensional measurement and, upon request, material analysis.
We guarantee the functional restoration of old, historic, naval, and industrial electric motors, offering a rapid solution to avoid prolonged downtime.
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
OUR WORKFLOWAn integrated process of absolute precision
- Measurement and analysis: we use high resolution measuring machines and 3D modelling software to reconstruct original geometries, even starting from damaged or worn sheets.
- Magnetic identification: upon request, we check the grade of the original steel to propose the most efficient material between NGO (Non-Grain Oriented) or GO (Grain Oriented) electrical steel.
- Internal engineering: our engineering department designs custom stacking tools for each individual project, ensuring precise coaxiality between stator and rotor.
- Fiber laser cutting machines: fast manufacturing with 2 kW fiber laser systems with a precision of +/- 0.025 mm on working table up to 3000×1500 mm.
- Advanced assembly methods: we offer TIG/Laser welding or BACKLACK technology to minimize vibrations and maximize thermal stability.
