Abstract
Embodiments generally relate to linear variable displacement transformer (LVDT) position sensors. The position sensor comprises a bobbin, a moveable core, a primary coil of wire wound around the bobbin, and two secondary coils of wire wound around the bobbin about the primary coil using a fractional winding technique. For example, the winding length of the bobbin may be separated into three consecutive parts. Generally, the primary coil may be wound around the entire winding length of the bobbin. The first secondary coil may be wound around the first and second parts of the winding length. The second secondary coil may be wound around the second and third parts of the winding length. Additionally, the first secondary coil and the second secondary coil may overlap over the second part of the winding length.
