摘要:
A redundant angular position sensor comprising a first angular position sensor including a first excitation coil, a first sensing coil and a second sensing coil and a second angular position sensor. The second angular position sensor including a second excitation coil, a third sensing coil and a fourth sensing coil. Each of the first, second, third and fourth sensing coils comprising a respective clockwise winding portion and a respective counter-clockwise winding portion. The redundant angular position sensor further comprises a rotatable inductive coupling element positioned in overlying relation to the sensing coils and separated from the sensing coils by a gap, wherein the rotatable inductive coupling element comprises four, substantially evenly radially spaced, sector apertures.
