Abstract

The invention relates to an electromagnetic actuator (10) comprising a ferromagnetic housing (12), two electromagnetic coils (14, 16), a ferromagnetic unit (24), a ferromagnetic plunger (22), the the ferromagnetic housing extends in a longitudinal direction (X) and has a height (H1) in a vertical direction (Z) perpendicular to the longitudinal direction (X), the two electromagnetic coils are positioned within the housing (12), and Each comprises at least one winding (36, 38) around the longitudinal direction (X), the ferromagnetic units are arranged between the coils (14, 16), the ferromagnetic plungers are subjected to the electrical force produced by the coils (14, 16) Magnetic field, the plunger (22) is movable in the longitudinal direction (X) and can be fixed in three different longitudinal positions depending on the field produced by the coils (14, 16). The ferromagnetic unit (24) is rigidly connected to the housing (12) and has a dimension (H2) in the vertical direction (Z) greater than one sixth of the height (H1) of the housing (12), the iron The magnetic unit (24) is also positioned relative to the midplane (P) at a distance less than one quarter of the gap (E) between the two coils (14, 16) in the longitudinal direction (X), the The midplane is perpendicular to the longitudinal direction and is located midway between the two coils (14, 16).

Description

technical field [0001] The invention relates to an electromagnetic actuator. The actuator includes a ferromagnetic housing extending in a longitudinal direction and having a height in a vertical direction perpendicular to the longitudinal direction. The actuator includes two electromagnetic coils positioned within said housing, each including at least one winding around a longitudinal direction. [0002] The actuator also includes a ferromagnetic unit positioned between the coils, and a ferromagnetic plunger subjected to the magnetic field generated by the coils, said ferromagnetic plunger being movable in the longitudinal direction and capable of being fixed in a position depending on Three different longitudinal positions of the field generated by the coil. [0003] The invention also relates to a method for manufacturing such an electromagnetic actuator. Background technique [0004] From document EP2250651, an electromagnetic actuator comprising two coils, a plunger c...
