Parametric design of magnetic sensor for transverse flux linear motors

This paper shows a process for designing of a magnetic sensor used in position measurement of a transverse flux linear motor (TFLM). Parametric method is adopted using several chosen variables. This sensor operates based on the principle of hall effect and hence magnetic flux density is focused. The design target is to obtain very low total harmonic distortion (THD) which should be less than 3% and peak flux density is expected to be above 0.1T. The specifications of the designed sensor are verified by the FEM analysis and some experiments.
