Variable Electromagnetic Drive Train - Dynamic TSR (Variable Swept Area VAWT) With Integrated Control Mechanism

Resumen de: NL2039181A

0001 This invention. introduces an advanced. Variable Electromagnetic Drive Train specifically designed to optimize the Angular speed of wind turbines, particularly vertical axis wind turbines (VAWTs), under different wind conditions. The system achieves efficient RPM optimization through its electromagnetic drive train, enabling the generator to maintain optimal performance independently of the turbine's rotational speed. Torque optimization is accomplished via one of these methods. First, the drive train dynamically adjusts the Tip—Speed Ratio (TSR), allowing the turbine to adapt to varying wind intensities by adjusting the swept area—arms. Second, an additional stator layer within the electromagnetic drive train provides precise control over torque. This design within the electromagnetic drive train enables fine—tuned adjustments to both speed and torque, maximizing energy capture and maintaining consistent power output. By decoupling the generator’s operating parameters from fluctuating wind speeds, this system enhances efficiency and reliability across a wide range of environmental conditions. This innovative approach is also applicable to horizontal axis wind. turbines (HAWTs) and other mechanical systems where precise control over RPM and torque is essential. The variable electromagnetic drive train technology thus provides a flexible, adaptable solution for sustainable energy generation and mechanical applications requiring robust control over dynamic loads
