Title
(EN) ELECTROMAGNETIC ACTUATOR HAVING A CYLINDRICAL TRANSLATION COIL AND A TOROIDAL ROTATION COIL, ACTUATOR UNIT COMPRISING THE ACTUATOR AND A MEASUREMENT SYSTEM, AND MACHINE COMPRISING THE ACTUATOR OR THE ACTUATOR UNIT
(FR) ACTIONNEUR ELECTROMAGNETIQUE A BOBINE DE TRANSLATION CYLINDRIQUE ET BOBINE DE ROTATION TOROIDALE, UNITE D'ACTIONNEMENT COMPRENANT L'ACTIONNEUR ET UN SYSTEME DE MESURE, ET MACHINE COMPRENANT L'ACTIONNEUR OU L'UNITE D'ACTIONNEMENT
Abstract
(EN)
An electromagnetic actuator (1) comprises two actuator sections which are translatable relative to one another along an actuator axis (1a) and which are rotatable about the actuator axis, a first actuator section (1) comprising a coil system and a second actuator section (3) comprising a permanent magnet system for cooperation with the coil system $i(via) an air gap. The coil system is arranged on a magnetically conductive yoke (5) and comprises a cylindrical translation coil (9) and a toroidal rotation coil (7), which are coaxial with the actuator axis. The permanent magnet system comprises an annular magnet (11), which is coaxial with the actuator axis, for cooperation with both the translation coil and the rotation coil. The magnet has a radial magnetisation (B) which is interrupted by an annular segment (13). The magnetically conductive yoke has a central core (5b) around which the translation coil is arranged and a shell (5a) on which the rotation coil is disposed. The core and shell bound a space within which the annular magnet is disposed, the magnetically conductive yoke comprising a bridge (5c) connecting the central core and the shell.
(FR)
Un actionneur électromagnétique (1) comporte deux éléments d'actionnement à translation relative l'un par rapport à l'autre le long d'un axe d'actionnement (1a) et mobiles autour de l'axe de l'actionneur. Le premier élément d'actionnement (1) comporte un dispositif à bobine, et le second élément d'actionnement (3) un dispositif d'aimant permanent destiné à coopérer avec le dispositif à bobine via une couche d'air. Le dispositif à bobine, moulé sur une carcasse (5) magnétiquement conductrice, comporte une bobine de translation cylindrique (9) et une bobine de rotation toroïdale (7) qui sont dans le même axe que l'axe de l'actionneur. Le dispositif d'aimant permanent comporte un aimant annulaire (11) dans le même axe que l'axe de l'actionneur et coopérant à la fois avec la bobine de translation et la bobine de rotation. L'aimant présente une magnétisation radiale (B) qui est interrompue par un segment annulaire (13). La carcasse magnétiquement conductrice comporte un noyau central (5b) autour duquel est placée la bobine de translation, et un manchon (5a) sur lequel est montée la bobine de rotation. Le noyau et le manchon délimitent un volume dans lequel l'aimant annulaire est placé, la carcasse magnétiquement conductrice comportant un pont (5c) reliant le noyau central et le manchon.
