Benefits of technology

This patented technology improves on previous methods for controlling unwanted vibrations during operation (such as those associated with turbines). It allows for precise and stable rotation without requiring excessive force or adjustments from other components that may affect its performance. Overall this new technique helps improve efficiency and reduce costs while maintaining good quality products.

Problems solved by technology

This patents discusses different ways to improve the performance of maglev thrusters without causing any unwanted movements during operation. One way involves reducing the influence from external forces like gravity weight fluctuations, called shaft tension variations. Another approach includes adding dampening elements between the rotating part's support ring and the stationary body frame, eliminating interference motions altogether. These techniques aim to achieve better balance behavior and reduced vibrational noise levels under certain conditions.
