Title (EN) MONOPHASE ELECTROMAGNETIC ACTUATOR
(FR) ACTIONNEUR ELECTROMAGNETIQUE MONOPHASE
Abstract:
(EN) The invention relates to a monophase electromagnetic actuator comprising a stator structure and a movable member having a thin magnetized part. The thin magnetized part presents two polar portions (1, 2) separated by a separation line (3). The width of the polar portions (1, 2) varies continuously along the displacement path of the movable member. Application: instrumentation, automatic systems, linear or rotary actuators.
(FR) La présente invention concerne un actionneur électromagnétique monophasé comportant une structure statorique et un organe mobile comportant une partie aimantée mince. La partie aimantée mince présente deux parties polaires (1, 2) séparées par une ligne de séparation (3). La largeur des parties polaires (1, 2) varie continûment le long du chemin de déplacement de l'organe mobile. Application: instrumentation, automatisme, actionneur linéaire ou rotatif.
