The crankshaft position sensor based on magnetoelectric materials

This paper is devoted to the research of possibilities of applying of the magnetoelectric material as the sensing element of a crankshaft position sensor. Proposed magnetoelectric crankshaft position sensor would have several advantages against the traditional sensors such as smaller size and weight. Magnetostrictive-piezoelectric layered structure based on piezoceramic PZT plate with dimensions 0.5 mm of thickness, 30 mm of length and 10 mm of wide was used as an element of a sensor. The designed sensor showed the peak voltage pulse of 1.4 V. Proposed design with using the magnetoelectric material may be applied to creation of position and displacement sensors.
