Question

What is a synchro? Write its transfer function.

Answer 1

A synchro is a generic name for electromagnetic transducers that produce an electric voltage (emf) depending on the angular position of the coil axis in the stator to the rotor axis.

Here is the tranfer function of a synchro:

em = K' Er φ(t) sin ωt

where;

K' is a proportional constant

and φ(t) value is small
