Introduction
Mecc Alte has been a specialist in alternators for over 60 years, focusing on producing reliable alternators for various applications. The company has introduced the Njorgen series of mini wind turbines to address the growing demand for sustainable and cost-effective electricity generation.

Market Context
The market for small wind turbines is expanding rapidly due to their adaptability and ease of use. However, the lack of industrialized components with specific performance designs poses challenges for new turbine producers, leading to increased costs and delayed market entry.

Mecc Alte Njorgen Solution
To bridge this gap, Mecc Alte has developed the Njorgen series of alternators, designed specifically for small wind turbine applications. This series complements the successful Eogen series and ranges from 5kW to 20kW. The Njorgen alternators feature an oversized double bearing design, making them suitable for both vertical and horizontal wind turbines.

  • 34 Poles, voltage tuned on customer request
  • Designed for a lifespan of over 20 years
  • Utilizes NeFeB magnets
  • IP55, totally enclosed generator for reliability
  • Low friction SKF bearings
  • Nominal speed of ~150rpm, with a maximum speed of up to 4200 rpm
  • Minimized starting and cogging torque
  • Efficiency greater than 92.5%, featuring cold copper design
  • Can be integrated into mast or hub
