Abstract
In a rotation detecting apparatus, each of first and second sensor elements measures rotation of a detection target. A circuit module includes first and second rotational angle calculators each calculating, based on a corresponding one of a first measurement value of the first sensor element and a second measurement value of the second sensor element, a rotational angle of the detection target. The circuit module includes first and second rotation number calculators each calculating, based on the corresponding one of the first measurement value and the second measurement value, a rotation number of the detection target. The circuit module includes first and second communicators each outputting, to a controller, a rotational angle signal based on the rotational angle and a rotation number signal based on the rotation number. A package packages the first and second sensor elements, and is mounted to a circuit board separately from the controller.
