The air gap is the distance separating the armature 11 from the yoke 9 when the coil is not energised. It will be necessary to adjust it when the brake no longer releases normally or when its value reaches 1.5 mm.

The brake rectifier converts the mains voltage into a DC voltage. An electromechanical brake is controlled and released with this DC voltage. The power supply to the brake is interrupted by switching off the mains voltage.
