ELIN Motoren designs generators ranging from 2 MW to 8 MW for onshore wind applications. The power rating selected depends on the turbine rotor diameter, the site’s wind speed classification according to IEC 61400-1 and the grid connection capacity. The 3–7 MW range represents the current delivery volume of ELIN Motoren.

Frequently asked questions
What power classes are available for wind generators?
How often must a wind generator be serviced?
Annual inspections verify operational parameters including insulation condition, bearing lubrication, and cooling system function. Major overhauls every 3-5 years include bearing replacement, comprehensive electrical testing, and mechanical component inspection. Condition monitoring enables interval extension when operational data confirms healthy system status, reducing lifecycle maintenance costs.
What environmental protection is standard for wind generators?
ELIN Motoren wind generators incorporate multi-layer coating systems tested to ISO 9227 salt spray standards, IP55 to IP65 ingress protection ratings, and climate class H ratings for extreme temperature operation. Sealed cable entry systems prevent moisture ingress into electrical compartments even in high-humidity coastal environments.
Can ELIN Motoren retrofit generators for existing wind farms?
Yes. ELIN Motoren engineering analyzes existing generator specifications, mechanical interfaces, and electrical parameters to design drop-in replacement solutions. Retrofit projects typically achieve increased power rating and efficiency while maintaining original mounting dimensions, minimizing turbine modification requirements and installation costs.
Learning from the field. Our latest upgraded rotor design incorporates targeted improvements in areas where earlier generation systems have historically shown weaknesses:
– Advanced Winding Design for improved thermal performance and durability in demanding conditions
– Reinforced Star-Ring Structure for enhanced current control for consistent operation
– Optimized Slip Ring Connection for stronger interface for stable, reliable energy transfer
