What is accomplished by adding an additional winding placed in the synchro?

Adding an additional winding in a synchro plays a crucial role in enhancing the performance of the system, specifically by contributing to electrical damping. When a synchro experiences changes in its input signal, the additional winding helps counteract oscillations that can occur. This is important because it allows the synchro to respond more smoothly and accurately to position changes by reducing transient spikes and stabilizing feedback. Damping improves the overall response of the system, making it more reliable in delivering accurate position information, which is critical in applications like navigational systems and control mechanisms. The presence of the additional winding effectively minimizes the potential for overshooting or oscillation, which is essential for precision in the synchro's operation.
