摘要： A magnetic sensor of rotary, linear, or curvilinear displacement using at least one permanent magnet and at least one magnetosensitive element, which can move with respect to one another. The magnet exhibits a direction of magnetization that varies continuously along the direction of displacement, with the exclusion of a diametral magnetization in the case of a rotary sensor.

摘要： An electromagnetic actuator includes a stator unit having N poles having the width LP, and at least one coil surrounding one of the poles, wherein N≦3, and a magnetic portion, which is movable, relative to the stator unit, in a direction of relative movement and over a course of travel C, and including N+1 magnetized areas, the magnetizations of which are perpendicular to the relative movement direction and in alternate directions. The magnetic portion includes a yoke for closing off the magnetic fluxes passing through the magnetized areas, the course of travel C of the magnetic portion being less than or equal to the width LP of each pole, and the thickness of the magnetized areas perpendicular to the direction of movement being less than the course of travel C of the magnetic portion.

摘要： A contactless position sensor comprises a permanent magnet generating a magnetic field and at least one element for detecting magnetic fields (or magneto-sensitive element) in at least two directions. The permanent magnet is capable of moving in a movement direction and has a continuously variable magnetization in the movement direction. The variation in the magnetization has, along the different field components, a shape corresponding to a combination of at least two different quasi-periodic contributions. The sensor further comprises a computer for combining the values of these field components and for determining a precise value of the position.
