摘要:
A method for fault prevention in electric drives in industrial automation, including recording sound level signals inside of the electric drive during operation with known sound propagation geometry and known distance to the source of sounds, continuously comparing the sound power with a reference sound power and monitoring of the exceeding of the maximum value of the sound energy, continuously adding up the sound power over time when the sound power exceeds the reference sound power, continuously subtracting the sound power over time when the sound power falls below the reference sound power, with a minimum value of zero, and generating a warning or alarm when the maximum value of the sound energy is exceeded.

Linear motor having optimized power, including a U-shaped profiled stator housing, which forms an inner installation space for receiving a winding packet consisting of multiple coils. The installation space is delimited on the cover side by a carriage driven so it is longitudinally displaceable by magnetic force on the stator housing, on which carriage a length scale is fastened, opposite to which a position sensor is arranged in the stator housing. The installation area for the arrangement of the winding packet in the stator housing is uninfluenced by the position sensor also arranged in the stator housing.
摘要:
A method for force calibration, force computation and force limitation of iron core linear motors by detecting interfering influences during the operating of the sled, wherein a winding current measured in the linear motor is used as value for these interfering forces, and the sled of the linear motor with all add-ons but without application forces over a desired travel area with a one-time calibration and, in the process, at least one interfering current value and at least one position value are recorded and stored by at least one current and position sensor per travel interval, wherein the interfering current value represents the sum of the interfering forces and, in the later application operation, the saved data record of interfering current and position values is interpolated and used as compensation value for computing the force-proportional application current of the linear motor.
摘要:
A device for positioning an end effector in a space spanned by a longitudinal direction, a transverse direction and a vertical direction has: a first linear rail aligned in the longitudinal direction and on which a first longitudinal slide is arranged so as to be movable in the longitudinal direction, a second linear rail aligned parallel to the first linear rail in the longitudinal direction and on which a second longitudinal slide is arranged so as to be movable in the longitudinal direction, and a third linear rail guiding a cross slide connected to the first linear slide via a first guide element and to the second linear slide via a second guide element, characterized in that the first guide element is a first spring structure that is rigid in the vertical direction and the second guide element is a second spring structure that is rigid in the vertical direction.
摘要:
An electrically conductive housing with cable strain relief and shield connection, wherein a cable is introduced into a recess of the housing, wherein the strain relief includes a thrust member that can be displaced radially in the recess of the housing and the thrust member is biased with at least one housing-side clamping screw, presses the cable sheathing of the cable against a housing-side mold surface opposite the thrust member. The recess passes through the device wall of the housing in whose wall area the thrust member is arranged. The housing-side mold surface opposite the thrust member includes an mold surface conformed approximately to the outer shape of the cable sheathing that transitions into the recess in the device wall enlarged in comparison to the mold surface.
