What Castelomega does

CastelOmega is a Barcelona-headquartered industrial services company (CASTELOMEGA, S.L.U.) that has specialized since 2000 in the repair, renovation, exchange, and testing of electric motors, electro spindles, precision heads, and industrial electronics. The company serves industrial customers across machine tool manufacturing, aerospace, automotive, food processing, energy, transportation, and tertiary facility sectors in Spain and internationally (reportedly across five countries). Its technical capabilities span component-level industrial electronics repair (including BGA rework and EPROM programming), high-speed spindle balancing and testing up to 40,000 RPM, encoder/resolver alignment, DC motor commutator machining, and predictive vibration analysis per ISO 10816/20816 standards, backed by ISO 9001, ISO 14001, ISO 45001, WCA, and SAQR-ATEX certifications. Authorized service partnerships with Siemens (since 2001) and Weiss Spindeltechnologie GmbH (since 2008), plus servicing arrangements with Sieb-Meyer, HSD Mechatronics, Innomotics, and BSH Group, anchor its brand credibility.

The business operates through four revenue streams: (1) repair and maintenance services including 24/7 emergency on-site and workshop-based repair, (2) equipment sales of new, refurbished, and exchanged motors and electronic components, (3) engineering and R&D services covering custom test bench design and machine reconversion, and (4) retrofit services for obsolete machinery modernization. Pricing is quote-based with no publicly disclosed rates, supported by free initial diagnostic assessments. Go-to-market is enterprise field sales directed at industrial plants, complemented by regional offices in Madrid (2011) and Vigo (2019), technical content marketing via blog and social channels, and trade show participation (BIEMH 2026). The company is privately held with no disclosed parent, investors, or funding rounds.
