AI Technical Summary

Technical Problem

Existing anti-roll gyroscopes rely on adjusting the motor speed to restore torque. Frequent adjustments affect the motor's lifespan and make it difficult to achieve fine torque adjustment.

Method used

A variable moment of inertia multi-degree-of-freedom anti-roll gyroscope is adopted. The first driving component drives the base and stator to rotate, the second driving component drives the stator to swing, and the third driving component adjusts the distance between the counterweight and the stator axis. Multiple counterweights are used to form a split rotor to realize the adjustment and fine adjustment of the restoring torque.

Benefits of technology

It extends the service life of the drive motor, enables precise adjustment of the restoring torque, and improves the convenience and stability of the application.
