What method is used in synchro receivers to prevent the rotor from oscillating or spinning?

Damping is the method employed in synchro receivers to prevent the rotor from oscillating or spinning. In the context of synchro systems, damping involves using various techniques or physical elements to absorb excess kinetic energy and mitigate oscillations caused by external forces or intrinsic system dynamics. This is crucial for maintaining accuracy in position feedback systems, as it ensures that the rotor stabilizes at the correct angle without excessive vibrations that could lead to erroneous readings or erratic operation.

The process typically involves integrating resistive components or other materials that provide a controlled level of friction or resistance, thus slowing down the rotor and allowing it to settle into its final position more smoothly. By managing the dynamics of the rotor's motion, damping enhances the reliability and fidelity of the synchro system, resulting in improved performance and measurement accuracy.
