Detector for determining rotational speed and position for an internal combustion engine |
摘要 |
A rotational position detecting apparatus for an internal-combustion engine for use with a Hall IC comprising at least two Hall elements for detecting the protrusion of a rotator. One of the two Hall elements is arranged with a magnet for forming a magnetic field, and the magnet is disposed on one side of the Hall IC to form a magnetic circuit for converging the magnetic flux on only one element within the Hall IC.
