—The main goal of this paper is to present a novel 3D
analytical method for precise and fast modeling of rotational eddy
current speed sensors with cylindrical structures. An equivalent
linearized model is developed using a multi-slice structure. The
cylindrical structure of rotational eddy current sensors is modeled
using the multi-slice linearized structure. The 3D distribution of
induced eddy current in the rotating conductive rods is considered
in the analytical modeling. The method of separation of variables
using Fourier series is utilized for the analytical analysis of rotational
eddy current speed sensors. The new calculation method is tested
on the eddy current speed sensor with perpendicular coils and
different rotating rods. The analytical results are compared with the
calculations of 3D time harmonic and time stepping finite element
methods. The measurements on the sensor prototype verified the
calculations. When compared to the 3D Time Harmonic FEM, the 3D
analytical method is 12-times faster.
