ABSTRACT:
A calculation processing circuit10executes a predetermined operation on the detection signals of a plurality of magnetic sensors A and B, disposed to face a target3amade of a magnetic material and provided on a rotating member6, for outputting detection signals with mutually different phases according to a rotation of the rotating member6, calculates the electrical angle of the detection signals based on a table2arepresenting the correlation of the result of the operation executed in advance with a corresponding electrical angle of detection signals, and detects the rotational angle of the rotating member6based on the calculated electrical angle. The calculation processing circuit10stores a plurality of tables2athrough2cfor different gaps between the target3aand the magnetic sensors A and B, determines the gap based on the detection signals of the magnetic sensors A and B, and calculates the electrical angle of the detection signals based on the table corresponding to the determined gap.
