  • Page 17 When the button is released, the magnet coil is deenergized and the movable core is returned by spring to press the brake disk. The fixed core is divided into two parts (inside half and outside haft). The inside half is set back 0.3- 0.4mm in height from the outside half. When the movable core is pulled, the outside half comes into close contact with the movable core, but a gap (0.3- 0.4mm) will be produced between the inside half and the movable core (this gap is necessary to eliminate residual magnetic flux).
