The present disclosure discloses a split-type electromagnet, wherein the split-type electromagnet comprises a housing and an iron core, the housing and the iron core are of a split type, wherein the iron core is fixed within the housing after the coil has been wound on the iron core, and the housing is a cylindrical body or an ellipsoidal body or a cross section of the housing is a sector-shaped ring or a rectangular ring. Compared with the integrated type of the housing and the iron core in the prior art, the winding of the coil of the electromagnet is more convenient. Furthermore, when the cross section of the housing of the electromagnet is a sector-shaped ring, a plurality of electromagnets are combined to form an electromagnet unit, and when the space is restricted, the electromagnet unit may be used to complete the electromagnetic attraction.

A solenoid valve having a movable valve element (5) that is movable by an electromagnet (10), wherein the electromagnet (10) has a magnet pot (13) having a recess (14) in which a solenoid coil (12) fixed on a coil body (11) is arranged. A sealing element (15) is arranged on the coil body (11) or a sealing body (17) fixedly connected to the coil body (11), which sealing element seals the recess (14) of the magnet pot (13) from the outside.

The present disclosure provides a solenoid assembly that includes a static housing, a plunger disposed within the housing and translatable along an actuation axis in response to a magnetic actuation force, an intermediate element disposed within the housing and surrounding at least a portion of the plunger that is also translatable along the actuation axis in response to a magnetic actuation force. A coil arrangement is disposed within the housing and provides a first and second magnetic actuation force in response to electrical excitation thereof. The coil arrangement is arranged such that the first magnetic actuation force is configured to translate the intermediate element and the plunger together with respect to the static housing, and the second magnetic actuation force is configured to translate the plunger with respect to the intermediate element. This can improve the stroke length of the solenoid assembly.

A stator coil assembly is provided comprising: a stator having a stator core; a cover positioned within the stator core; a top section coupled to the cover to define an interior region, the top section including a pair of protrusions, each protrusion having a bore extending therethrough; a bobbin disposed within the interior region; a plurality of coil windings wrapped around the bobbin; a pair of lead wires, each lead wire extending through a corresponding protrusion bore and connecting to the coil windings within the interior region; and a pair of hermetic seals, each hermetic seal surrounding a corresponding lead wire within a protrusion bore to hermetically seal the interior region.

A curved haptic actuator according to an embodiment may comprise: a housing having a receiving space and having a shape where the receiving space and an outer appearance thereof are bent outward; a vibration unit disposed in the receiving space, being movable along the longitudinal direction of the housing, and having a shape bent upward; elastic bodies connected to an inner wall of the housing and both sides of the vibration unit; and a magnetic field generation unit which is installed on the inner wall of the housing and generates a magnetic field and applies the magnetic field to the vibration unit.

A solenoid device includes a yoke, a core, a shaft, a bobbin, a coil, a plunger, a lid, and a housing. A housing body part of the housing has a first opening; a first inner wall part expanding toward the outer side in the radial direction on an inner wall; and a first caulking part extending from the rear side end. The first inner wall part has a first step part extending toward the outer side in the radial direction at an end on the other side in the axial direction. A first cylindrical part of the yoke has a first flange part. The first flange part contacts the first step part with an end surface on the other side in the axial direction. The first caulking part is bent toward the inner side in the radial direction to contact a circumferential edge part of the lid.

A bi-stable solenoid includes a housing, a wire coil arranged within the housing, a first pole piece, a second pole piece, an armature slidably arranged within the housing, and a permanent magnet arranged within the armature between a first armature portion and a second armature portion. The first armature portion and the second armature portion are fabricated from a magnetically permeable material. Selective energization of the wire coil generates a wire coil flux path and is configured to move the armature between the first stable position and the second stable position. The first stable position is established by magnetic flux of the permanent magnet shorting through the first pole piece, and the second stable position is established by the magnetic flux of the permanent magnet traversing the wire coil flux path.
