摘要： Disclosed herein is an inexpensive tubular electromagnetic solenoid which employs stamped and drawn parts with a minimum of machined parts. The tubular housing is deep drawn and has a relatively light gauge side wall and an integrally formed end wall with apertures for pin terminals. A stamped flux enhancing disc is anchored exteriorly of the end wall and is swaged to a projecting portion of a pole piece located interiorly of the end wall. The flux disc-pole piece assembly rigidifies the housing end wall and the pole piece supports and positions one end of the bobbin. Stamped washers having axial apertures interfit into the end of the tubular housing and receive and support the other end of the bobbin. The bobbin has integrally molded pin terminal support bosses which project through apertures in the end wall and position and support the terminations.

摘要： Magnetic actuator apparatus in which the armature is held in a restrained position on a magnetic core by magnetic flux whose density is cyclically varied in time, and the armature is selectively released by a bucking coil that is energized only when the armature retention flux is at low holding value. The flux source is a permanent magnet that is reciprocated or rotated to vary the armature retaining force.

摘要： There is disclosed a solenoid of improved construction and a facile method for its manufacture. The solenoid is intended for use with cyclic voltage supplies and has a fixed-position pole assembly of a pole piece, shading ring and flux ring which is secured in a retaining sleeve. The pole piece has an annular groove which receives an inward, annular bead of the sleeve to retain the assembly. The sleeve is mounted within a solenoid casing within an annular coil and the casing is closed by an end closure plate which bears against the end of the sleeve. The inward annular offset of the sleeve provides a resilient axial compressability of the sleeve permitting facile assembly to precise tolerances.

摘要： Disclosed herein are linear actuators and haptic actuators for providing haptic output on an electronic device. In some embodiments, the linear actuator comprises two linear arrays of permanent magnets within and fixed to a housing. The linear arrays are arranged in parallel planes oriented toward, and located on opposites sides of, a moveable assembly comprising a shaft having a ferritic core. The shaft comprises a set of conducting coils, each conducting coil being located between a magnet from each of the two linear arrays. The linear actuator comprises a support mechanism that is attached to both the housing and to the moveable assembly and is configured to pivot. An electromagnetic force can arise from a current in the coils to cause the moveable assembly to move linearly between the two linear arrays.

摘要： In one embodiment, a solenoid valve for a vehicle braking system includes a magnet assembly having a winding support, a coil winding, a housing, and a cover disc. The solenoid value further includes a valve cartridge having a capsule, a valve insert, a valve seat, and an armature. The valve insert can be connected to the capsule, the armature can be guided within the capsule in an axially movable manner and has a closing element. The closing element and the valve seat can form a valve that can control a fluid flow through the valve cartridge. The coil winding can be wound on the winding support to form an electrical coil, which can be controlled using control signals applied to electrical connectors. The electric coil generates a magnetic force that can move the armature against a force of a return spring.

摘要： A vibration actuator includes: a movable element having a magnet that is supported to be rotatable around a shaft, a weight supported to be rotatable together with the magnet, and an elastic supporting member wherein a rotation of the magnet and the weight is supported elastically; a coil that is supplied with an AC current at a frequency that is equal to a resonant frequency of the movable element; and a magnetic pole member that causes the movable element to undergo reciprocating a rotational vibration around the shaft through applying rotational torques in different directions alternatingly to the magnet by changing magnetic poles through the AC current that is applied to the coil.
