ELECTRO PERMANENT MAGNETIC SYSTEM WITH MAGNETIC STATE INDICATOR

摘要

An electro permanent magnetic system (10) for anchoring ferromagnetic material, with magnetic state indicator (14), comprising: an electro permanent magnetic module ( 12), a control unit ( 1 1 ) for said electro permanent magnetic module (12), an electrical connection system (13) between said control unit (1 1 ) and said electro permanent magnetic module (12); a magnetization indicator ( 14) for said electro permanent magnetic module ( 12) associated with the electro permanent magnetic module (12); characterised in that said magnetization indicator (14) is a bistable indicator having two stable states; said magnetization indicator (14) not requiring electrical power to remain in one of said stable states; said magnetization indicator (14) being electrically fed only in association with the magnetization or demagnetization of said electro permanent magnetic module ( 12), to pass from one stable state to the other of said two stable states.
