Which hybrid synchro has 2-phased stator windings and 3-phased rotors?

The hybrid synchro that features 2-phased stator windings and 3-phased rotors is known as a differential resolver. This type of resolver is specifically designed to convert angular position into a corresponding electrical signal, utilizing its unique winding configuration to achieve high accuracy and resolution.

The differential resolver operates by employing two coils in the stator that are 90 degrees apart, allowing it to measure the sine and cosine components of a rotational position. The rotor, which typically has three-phase windings, enables the resolver to provide a more precise output by utilizing the principles of phase difference. This setup is particularly beneficial in applications that require significant precision for position feedback, such as in aerospace and robotics.

Other options have distinct designs or functions that do not match the specific winding configuration mentioned in the question. The functionality of each is tailored to varied applications, making the differential resolver the correct answer regarding the unique hybrid synchro configuration described.
