Abstract
A rotation angle detector for detecting a rotation angle of a magnet rotator includes: the rotator with a magnet mounted on a rotation shaft; a sensor chip; and an operation element. The chip includes: first and second normal component detection elements for detecting a magnetic field along with a normal direction and first and second rotation component detection elements for detecting a magnetic field along with a rotation direction. A phase difference Δθ, output signals S, S, C, Cof the detection elements, a value Δbobtained by differentiating a component of the magnetic field along with the normal direction with respect to the rotation direction, and a value Δbobtained by differentiating a component of the magnetic field along with the rotation direction with respect to the rotation direction satisfies: The operation element calculates:
