ACTIONNEUR ELECTROMAGNETIQUE COMPORTANT DES MOYENS DE CONTROLE DE FONCTIONNEMENT AUTOADAPTATIFS ET PROCEDE UTILISANT UN TEL ACTIONNEUR

摘要

#CMT# #/CMT# The actuator (100) has a processing unit (2) acting on control units (21) based on mechanical stress (F) applied on the actuator. A mobile armature (12) is mounted inside a magnetic fixed yoke (11). The processing unit comprises self-adaptive control units with measurement units that measure total resistance of a trip coil (3) from reference electric current and/or reference voltage. The trip coil is connected to the control units that are connected to the self-adaptive control units by varying current intensity in the coil by the mechanical stress. #CMT# : #/CMT# An independent claim is also included for a method for determining mechanical stress applied on an electromagnetic actuator. #CMT#USE : #/CMT# Electromagnetic actuator e.g. monostable electromagnetic actuator and bistable electromagnetic actuator, for controlling an automatic tripping contactor or contactor type apparatus. Can also be used for switching an electric load i.e. electric motor, to be controlled. #CMT#ADVANTAGE : #/CMT# The measurement units authorize measurement or evaluation of operating parameters such as nature of the mechanical load and dynamic interactions applied to the actuator. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial sectional view of an electromagnetic actuator in an open position.
