Wind Turbine Generator Service — Siemens Gamesa
Do you operate Siemens Gamesa wind turbines? TEMISA Power Gen services the ELECTRICAL GENERATOR inside the nacelle — not the turbine, blades or gearbox. Rewind, repair, DFIG/PMG diagnostics and electrical testing, on-site and in-shop, under EASA AR100. Independent and multi-OEM.
Important: TEMISA does not repair the Siemens Gamesa turbine, blades or gearbox. We specialize in the electrical generator inside the nacelle — independent shop with no affiliation to Siemens Gamesa; the brand name is used only to identify the equipment. See the full scope in wind turbine generator repair in Mexico.
TEMISA Power Gen provides independent service to the ELECTRICAL GENERATOR inside Siemens Gamesa wind turbines. We rewind, repair and diagnose the generator on-site and in-shop under EASA AR100, IEEE and ISO standards, with coordinated response. We do not service the turbine or gearbox: our specialty is the electrical machine.
Generator topology
The G series (G52–G132) uses a doubly-fed induction generator (DFIG, wound rotor); the SG direct-drive platforms use a permanent-magnet synchronous generator (PMG) without a gearbox. Each topology requires a different service strategy.
The challenge in the generator
The Mexican fleet mixes the G series (DFIG with brushes and a converter) and SG direct-drive (brushless PMG, larger diameter). DFIG demands attention to the wound rotor and slip rings; PMG, specialized handling of the magnet rotor and large-format stator.
In Mexico
Siemens Gamesa holds one of Mexico's largest installed bases; the 2 MW-class G platforms are very common in the Isthmus wind zone and the north. The DFIG/PMG mix requires a shop capable of both technologies.

FAQ
FAQ — Siemens Gamesa wind turbine generator
Questions we often receive. Can't find yours? Email us at ventas@temisapowergen.mx.
Do you repair the Siemens Gamesa turbine or only the generator?
Only the ELECTRICAL GENERATOR and its associated system. We do not service blades, gearbox or nacelle; we are the independent ally on the electrical side.
Are you a Siemens Gamesa-authorized shop?
No. Independent, multi-OEM service to the generator; the brand reference is descriptive (service compatibility).
Do you handle both the G series (DFIG) and SG direct-drive (PMG)?
Yes. Service for the doubly-fed generator of the G series and for the permanent-magnet generator of the SG direct-drive platforms.
Which Siemens Gamesa models do you cover?
Generators from G52 to G132 and SG 5.0-132 / 5.8-170 / 6.6-170 platforms, low and medium voltage.
