How do fixed speed wind turbines work?

The fixed speed generator speed is achieved by continuously adjusting the angle of the wind turbine blades to achieve a constant speed. Constant torque is the premise. After the torque is determined, when the wind speed is different, the blades will automatically adjust. This is done. To maintain a constant speed, a direct-drive permanent magnet synchronous generator is required. It must be ensured that there is enough wind energy so that the blades of the generator can generate the torque to drive the generator to do work. Permanent magnet direct drive technology is already very mature.
