Contactless angular position sensor for measuring small angular position of control sleeve of aircraft, has magnetic sector intercepting apex angle that is greater than or equal to angular displacement and less than specific degrees

摘要

The sensor (1) has a magnetic structure (21) generating a magnetic field, and a magneto-sensitive element (11) secured to a stator assembly (10) or rotor assembly (20) and placed opposite to the structure. A magnetic sector (22) of the structure is arranged opposite to the element, where the sector comprises adjacent polar zones (23a, 23b) with equal size and alternated polarities. The sector intercepts apex angle in a plane orthogonal to a rotation axis (2), where the angle coinciding with the axis is greater than or equal to angular displacement (D) and less than 180 degrees.
