发明名称 Rotary angle measuring device with sensor coils surrounding rotor having axially offset regions
摘要 A measuring device for contactless determination of a rotary angle of a shaft has a movable body composed of at least one of an electrically conductive material and a ferro-magnetic material, and sensor coils relative to which the body moves and whose inductivity and alternating current resistance values are varied as a result of a relative change of a size of regions of the body which are associated with the coils. The regions of the body are provided in a number corresponding to a number of the coils and are offset relative to one another in an axial direction. Each of the coils extends over the regions of the body on opposite sides, so that each coil during a rotation of the body by 360 DEG is brought in operative connection with a whole associated surface of the regions.
