Rotational Eddy Current Speed Sensor
(IEEE, 2019)
A novel eddy current speed sensor is developed to measure the rotational speed of conductive objects. The sensor consists of one excitation coil and two pick-up coils around a rotating cylinder or rod. The sensor does not ...
Design and modeling of a linear speed sensor with a flat type structure and air coils
(Elsevier, 2020)
This paper presents the design and modeling of a linear eddy current speed sensor with a flat type structure and an air coil configuration. The theory of the eddy current speed sensor is based on utilizing the speed component ...
Transformer position sensor for a pneumatic cylinder
(Elsevier, 2019)
A novel transformer-based sensor for a pneumatic cylinder enables measurements of the piston position to be made through a thick conductive cylinder. Unlike existing industrial solutions, which are mainly based on a moving ...
The apparent permeability and the amplification factor of magnetic wires and wire arrays
(Elsevier, 2021)
We have calculated and plotted the apparent permeability and the demagnetization factor of single magnetic wires. We have also confirmed the accuracy of the analytical formula for the conversion between the apparent ...
Magnetic position sensors
(IOP Publishing, 2022)
Magnetic position sensors are popular in industrial and automotive applications since they are robust, resistant to dust and oil, and can be cheap. This was traditionally accompanied by low accuracy. However, new precise ...
Multiwire Parallel Fluxgate Sensors
(IEEE, 2022)
Fluxgate sensors with straight wire or rod cores are used in NDT, portable gradiometers and sensor arrays and for the detection of small objects. We show that their sensitivity at the voltage output mode depends on the ...
Effect of external DC field on current transformers with amorphous and nanocrystalline cores
(Elsevier, 2022)
Nanocrystalline and amorphous stress-annealed and field annealed tapes are used for cores of DC-tolerant current transformers. We analyze the influence of external DC field of arbitrary direction on the performance of these ...
Modeling of hysteresis loops using rational and power functions
(Elsevier, 2021)
Simple and precise hysteresis models with a small number of parameters allowing fast calculation are required for the magnetic analysis, as the field is calculated in a very large number of points. This paper presents a ...
A Linear Eddy Current Speed Sensor With a Perpendicular Coils Configuration
(IEEE Vehicular Technology Society, 2021)
This paper presents a new linear eddy current speed sensor with rectangular-shaped coils. The excitation coil and the pick-up coil have a perpendicular configuration without a magnetic yoke. The proposed sensor is shorter ...
A Novel Structure of an Eddy Current Sensor for Speed Measurement of Rotating Shafts
(IEEE Power & Energy Society, 2023)
This paper presents a novel structure of an eddy current sensor for the measurement of rotational speed. The sensor has a perpendicular configuration of the excitation coil and the pick-up coil. Its maximum nonlinearity ...
