Solenoid actuator, use of a solenoid actuator and braking or clamping device for linearly moving and/or axially rotating components

摘要

The invention relates to a solenoid actuator, consisting of a magnet body (1), a magnet armature, a cover (3) closing the space in which the magnet armature travels back and forth, at least one electric coil (4), which is arranged in the magnet body (1) concentrically around the axis of travel of the magnet armature, and means (5) for power transmission, which are in operative connection with the magnet armature and protrude out of the solenoid actuator. According to the invention, the magnet armature of the solenoid actuator is an axially guided annular magnet armature (2), and the means (5) for power transmission are arranged coaxially around the axis of travel of the annular magnet armature (2). This has the advantage that the solenoid actuator allows long switching paths and a small construction, along with high tightening and holding forces. This also results in the up to 100% higher holding force of the solenoid, making it particularly suitable for the actuation of braking and clamping equipment for rods and cables.
