Abstract

PURPOSE:To vary an output voltage linearly throughout one rotation by arranging permanent magnets with said magnets being tilted with respect to a Hall element. CONSTITUTION:A rotary shaft part 1a is provided on the top of a first yoke 1. At the bottom surface of said yoke 1, a slanted surface 1 is formed. The rectangular permanent magnets 2 and 3 which are magnetized in the direction of thickness are fixed to said slanted surface 1b, so that the polarities of said magnets are different in the up and down direction. A second yoke 4 is arranged so as to form a right angle with respect to the rotary shaft of the first yoke 1 and to form a gap between the yoke 4 and the permanent magnets 2 and 3. The Hall element 5 is fixed to the second yoke 4 so that said element 5 faces the permanent magnets 2 and 3.
