Abstract
PURPOSE: To reduce external magnetisms and obtain high reliability by providing a magnetic shield composed of high permeability magnetic material besides constituting elements.
CONSTITUTION: A magnetic shield 5 composed of high permeability magnetic material is provided besides the angle detecting part composed of a magnetic memory medium 13 as an angle position information generating source and a ferromagnetic magnetoresistance element 6 as a magnetic sensor of the position information thereof. Since this enables the malfunctions caused on account of the signal magnetic fields being applied to the magnetic sensor to be considerably reduced, the angle detecting part may be so constituted as to become integral with a rotator such as a DC servo motor 1 which produces strong leakage magnetic fields. As a result, the angle detector of low cost and good accuracy capable of performing positioning in the wide response speed region from the standstill up to a high speed may be obtained.
