Publication number: 20080079521Abstract: An electromagnetic actuator comprising an actuator member (7, 8) movable under the action of at least one electromagnet (1) comprising a coil (3) associated with a core (2) arranged to channel magnetic flux generated by the coil (3) so that it loops through the actuator member, the coil comprising a winding (21) of conductor wire covered in a casing (20), and the electromagnet including at least one permanent magnet (4) disposed relative to the core (2) in such a manner that the core channels flux generated by the permanent magnet so that it loops through the actuator member. According to the invention, the casing of the coil covers at least part of the permanent magnet (4) in such a manner as to secure the permanent magnet (4) to the winding (21) of conductor wire, such that the conductor wire winding and the permanent magnet form a one-piece unitary assembly suitable for being fitted on the core.Type: ApplicationFiled: May 23, 2005Publication date: April 3, 2008Applicant: Valeo Systemes de Controle MoteurInventors: Christophe Maerky, Lucien Donce, Eddy Cheri-Zecote
