Abstract
An apparatus for sensing a rotating body includes a plurality of units to be detected provided on the rotating body; at least two sensing coils disposed to face the units to be detected; an oscillator including at least two capacitors respectively connected to the at least two sensing coils to form at least two oscillation circuits; and a rotation information calculator configured to count frequencies of at least two oscillation signals respectively output from the at least two oscillation circuits to generate a first count value and a second count value, and calculate a rotation direction of the rotating body based on a change in the first count value and a change in the second count value.
