ANGULAR POSITION DETECTOR USING MAGNETIC ELEMENTS

摘要

An angular position detector comprising means for establishing a magnetic field wherein a magnetic flux distributes in such a manner as to vary in accordance with the angular position of a rotary shaft. At least one pair of magnet effective elements each having a parameter varied in accordance with a density of a magnetic flux passing therethrough are placed in the magnetic field and incorporated in an electric circuit. The electric circuit connects the magnet effective elements in series to each other and impress a d-c voltage which is then divided into a voltage representing the variation of the parameter of the elements, namely, the angular position of the rotary shaft.
