Quiescent current-operated electromagnetic spring pressure-brake for use in e.g. small load electric drive of hoist utilized for handling goods in modern logistics, has ventilating unit acting on socket projected over surface of support

摘要

The pressure-brake (FDB) has a shaft supported by rotors, and a hand ventilating unit (HE) provided in a mountable or detachable form perpendicular to a rotational axis (A). The ventilating unit has a hand release bracket (1) that is rotatably mounted on a U-shaped fork (2) over bolts (4). The ventilating unit acts on a ventilating socket against force of a spring, where the socket is projected over a flat surface of a coil support and connected with an armature disk such that the ventilating unit is supported on the flat surface, where the coil support is made from ferromagnetic material.
