چکیده :

Synchros are electromagnetic position sensors used to determine the position of a rotating shaft. This paper discusses the impact of leakage flux from the Rotary Transformer (RT) on the induced voltages and the detected position of the Wound Rotor (WR) synchro. Various methods are proposed to mitigate the negative effects of the rotary transformer. To evaluate the effectiveness of these methods, they are assessed through 3-D Time-Stepping Finite Element Analysis (TSFEA) and experimental measurements on a prototype sensor.
