Abstract (en)
[origin: US2015211270A1] Device forming an electromagnetic lock comprising an electromagnetic suction pad (3) comprising an electromagnet (4), a counter plate (1) and an electric circuit comprising a current source designed to supply at least one coil of the electromagnet of the electromagnetic suction pad with an electric magnetisation current to create an electromagnetic field and an associated electromagnetic force pinning the counter plate and the electromagnetic suction pad against one another to close the lock; switching means designed to cut off the supply of current; and anti-remanent means for dealing with the remanent electromagnetic force which remains when the switching means have disconnected the supply of current to the electromagnetic coil.
