MIRZAEI, M., P. RIPKA, and V. GRIM. A Linear Eddy Current Speed Sensor for Speed Measurement of Conductive Objects. IEEE Transactions on Industry Applications. 2022, 2022 7847-7856. ISSN 0093-9994. DOI 10.1109/TIA.2022.3198625.
This paper presents the novel structure of an eddy current sensor for linear speed measurements. The sensor has one excitation coil and two pairs of antiserially connected pick-up coils, which are located inside and outside the excitation coil. The design and modeling of the sensor are considered with an air core and with a magnetic yoke (core) to compare their performances in terms of sensitivity and nonlinearity error. The experiments and the analysis are performed at different excitation frequencies and speeds. A novel 3D analytical method is developed and utilized for parametric analysis and for the design of this sensor. The simulation results are compared with measurements up to 16.7 m/s (60 km/h). The achieved nonlinearity error is as low as 0.3%
