Manufacturing

Large Scale Manufacturing

Marelli Motori operates one of Europe’s most advanced generators and alternators manufacturing facilities at its Arzignano headquarters, where specialist workers support the fully integrated production of industrial-grade machines up to 11.2 MW. The site combines large-scale manufacturing, R&D and vertically integrated processes to deliver high-output alternators for demanding energy and industrial applications.

In-house Vacuum Pressure Impregnation system (VPI)

VPI application techniques provides an optimum machine protection by using a correctly engineered combination of impregnating resin, insulation system and application process.

Technical features:

  • maximum impregnable diameter: 3150 mm
  • maximum stator weight: 20 ton
  • minimum pressure: 2mbar
  • maximum pressure: 6bar

Stringent Testing

A key strength of the Arzignano facility is its state-of-the-art test infrastructure, enabling full validation of generators and motors in both horizontal and vertical configurations. This ensures every machine meets stringent global standards and performs reliably across mission-critical sectors, including AI data centres, power generation, marine and oil & gas.
