Permanent magnets frameless alternators for Direct Drive of wind and water turbines
The range of STK Permanent Magnet alternators, also called permanent magnet generators, addresses the applications of Wind Turbine generators, windmill alternators or windmill generators for small wind turbines and small water turbines, that is to say in low and medium power needing the highest power-to-weight ratio in Direct Drive without gear for matching cost-effective solutions.
The range of AC frameless permanent magnet generators STK includes 6 sizes from 145 mm up to 800 mm available in four different lengths per size and two standard rated speeds. Their extremely compact design and high efficiency allow the use in direct drive in small wind turbines as wind turbine generators and windmill generators.
