摘要： The pole geometry of an electromagnetic switch valve includes a cylindrical well on the pole member, which is penetrated by a cylindrical pin on the magnetic armature. This obtains a magnetic force-stroke curve that first extends proportionally starting out from the initial position of the magnetic armature and then rises progressively until the magnetic armature reaches the end position. Continuously increasing the energizing of the magnetic drive upon shifting of the magnetic armature from its initial position into its end position enables the noise formation upon the closing process of the valve to be reduced. Accordingly, the noise formation upon the opening process of the valve can be reduced when the energizing of the magnetic coil is reduced not abruptly but continuously.

摘要： An electromagnetic actuating apparatus, in particular a proportional magnet or switching magnet, includes a magnet armature (4) guided for axial movement in a pole tube (2). The pole tube is at least partially surrounded by a coil winding and is adjoined by a pole core (10) via a separating region (20) forming a magnetic decoupling. On energization of the coil winding (52), a magnetic force acts on the armature (4) to move the armature (4) in the direction of the pole core (10) within a travel area. At least one insert (28) of ferromagnetic material with a preset axial thickness is between the armature (4) and the pole core (10) to shorten, as desired, the axial length of the travel area.

摘要： A device and a method are provided for determining a stroke of an armature of a magnetic valve which has a coil and the armature is displaceable by magnetic force, including: providing at least one reference data set which includes a magnitude of a current through the coil and a magnitude of the magnetic flux in the case of a known magnitude of the stroke; generating a current flow through the coil of the magnetic valve in order to generate a magnetic field for generating a magnetic force on the armature, which magnetic force displaces the armature in the direction for the opening of a closure element coupled to the armature; determining a magnitude of the magnetic flux when the armature abuts against a driver of the closure element; and determining the magnitude of the stroke based upon the determined magnitude of the magnetic flux and the reference data set.

摘要： An apparatus is provided for mechanically loading a biological sample. The apparatus comprises: a container for housing the biological sample; a ferromagnetic element, for attachment to the biological sample within the container; and a solenoid for generating a magnetic field within the container, so as to apply a force to the ferromagnetic element. The solenoid is configured, when energised by a constant current, to produce a force on the ferromagnetic element that varies by less than a predetermined amount over a predetermined range of movement of the magnet within the container. A method of mechanically loading a biological sample is also disclosed.

摘要： An actuator has an electrically conductive coil which has a longitudinal axis and a plurality of turns and a magnet arranged at a distance from the turns in radial direction relative to the longitudinal axis. The coil is partially covered by a central region of a first conducting element on a side which faces away from the magnet and the magnet is partially covered by a mid region of a second conducting element on a side facing away from the turns of the coil. The first conducting element projects beyond the coil and the second conducting element projects beyond the magnet in the direction of the longitudinal axis and there each have collar-like projections. The coil has a first winding turns region and a second winding turns region.

摘要： Electromagnetic actuators capable of generating a symmetrical bidirectional force are disclosed. The electromagnetic actuators include a housing made of a ferromagnetic material and a shaft made of a magnetically inert material movable along an axis within the housing. In one type of actuator, captive permanent magnets are arranged on opposite interior end walls of the housing and an electromagnetic coil is mounted on a central portion of the shaft. The electromagnetic coil is capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on the direction of current through the electromagnetic coil. In another type of actuator, captive electromagnetic coils are arranged on opposing inner end walls of the housing, and a permanent magnet is mounted on a central portion of the shaft. The electromagnetic coils are capable of generating a force when energized that causes linear displacement of the shaft in either direction along its axis depending on a direction of current through the electromagnetic coils.

摘要： Exercise apparatus (1) in which a person exercising exerts a force against a movable actuator (6) to which is applied an adjustable force by a load system which resists or assists the movement of the actuator and is connected to the actuator by cables (9). The load system comprises a fixed, longitudinally arranged coaxial series of coil units (15), each coil unit being independently connectible to a source of electric current. The series of coils provides an elongate passage (18), and a shuttle (19) of ferromagnetic material is mounted for relative longitudinal movement within the passage, in response to movement of the actuator. Passage of a current through a coil unit exerts a force on the shuttle when in that coil unit, and is controlled by a microprocessor (22).

摘要： An adjustable solenoid assembly with an adjustable threaded pole having an interference fit section to be used with a complementary threaded receiver (e.g., the bore of the top plate) with an interference fit section. The adjustable threaded sections are used to pull or push the interference fit sections together and allow for precise locating of the interference fit sections and adjustment. The threaded pole may be used to set and maintain a precision working air gap between the pole piece and the plunger of the electromagnetic solenoid assembly. The interference fit holds the pole piece into location while still allowing the solenoid to be adjustable without a loss in flux density.
