SUMMARY
The cut-in speed for small wind turbines, particularly those utilizing a single bearing on the rotating axis and a permanent magnet generator, is typically set at 3 m/s. This speed is crucial for the turbine to begin generating electricity efficiently. The conversion of 3 m/s is approximately 10.8 km/h or 6.7 mph, which is essential for understanding operational thresholds. Design considerations for achieving this cut-in speed include rotor diameter, blade pitch, and generator characteristics.
