Theoretical modeling and analysis of variable reluctance wheel speed transducer

Among various aircraft wheel speed sensors, the variable reluctance wheel speed transducer is widely used in the detection of aircraft wheel speed due to its high reliability and high resolution. In this paper, a fast dynamic modeling method of variable reluctance wheel speed transducer is studied, which is based on the air-gap permeance model of magnetic field division. Finally, it is verified by finite element simulation, and the influence of the changes of different geometric parameters on the detection signal is analysed. The conclusions of this paper can provide useful tools for optimizing the electromagnetic design of such wheel speed transducer.
