Abstract
In some aspects of what is described herein, an aircraft wheel speed sensor system includes a pair of conductors coupled between an electro-mechanical system and a control system. The control system is configured to apply a carrier voltage signal to the pair of conductors and to detect a modulated current signal on the pair of conductors. The electro-mechanical system includes a stator and a rotor that moves upon rotation of an aircraft wheel. The stator includes a winding disposed about the rotor. The winding is configured to produce the modulated current signal on the pair of conductors in response to movement of the rotor. The modulated current signal has a frequency that is dependent on a rotational speed of the aircraft wheel.
