BRAKE DEVICE, ARRANGEMENT FOR CONTROLLING MOVEMENTS OF ACCESS MEMBER, AND ACCESS MEMBER SYSTEM
A brake device (12a, 12b) comprising a hard magnet (20); a soft magnet (22) configured to switch polarity between a first polarity and a second polarity when being subjected to a magnetic field and configured to maintain the polarity when the magnetic field is removed; an electric coil (24) located around the soft magnet; an electric control system (16) configured to apply a current pulse to the electric coil to generate the magnetic field for changing the polarization of the soft magnet; and a brake element (18) comprising a magnetic target section (28), the brake element being arranged to move to a released position (40) when the soft magnet adopts the first polarity, and arranged to move to a braking position (64) due to a magnetic field generated by the hard magnet and the soft magnet in combination and acting on the magnetic target section when the soft magnet adopts the second polarity.
