Definitions
- the invention relates to an electromagnet according to the preamble of the first claim.
- Electromagnets that convert an electric current into a mechanical force are known, for example from the document
- Such electromagnets usually consist of a stator and a stator
- pole core which is adjacent to the armature and defines a variable axial air gap between it and the armature.
- the yoke advantageously also stores the anchor.
- Electromagnets are the yoke and the pole core and a spacer soldered together and together form a pole tube.
- the spacer ring is made of a metallic material with very low magnetic conductivity, while the yoke and the pole core of
- the low magnetic conductivity of the spacer is required to avoid a magnetic short across the axial air gap.
- Execution can be made at a lower cost, but it has a significantly higher hysteresis of variable stroke force.
- the low hysteresis of the variable stroke force of the electromagnet is achieved by geometrically designing the yoke and the pole core as is conventional in the example with the brazed pole tube and by supporting the armature in the yoke.
- a spool core which consists of the yoke, the pole core, a pole piece and the plastic mass with which the metallic parts are encapsulated or surrounded.
- the plastic mass also fulfills the task of connecting the metallic parts of the spool with each other.
- the yoke has a flange which is molded or pressed on as a separate component.
- the gap between the yoke and the pole core is filled with the plastic mass.
- the coil core thus produced is wrapped with the magnetic coil and enclosed with a housing, which also has the property of
- the yoke is provided with a perforated end disc, either by welding the disc to the yoke or by pressing the disc into the yoke.
- Electromagnets of the type described are used for actuating fluid valves or clutches, preferably in vehicles or in mobile working machines.
- Fig. 1 shows the electromagnet in section.
- the electromagnet (1) according to FIG. 1 consists of at least one magnetic coil (2) wound on a coil core (6), a housing (3)
- the coil core (6) contains the yoke (7), the pole core (4) and the
- Interspace (10) between the yoke (7) and the pole core (4) is filled with the plastic mass.
- the pole core (4) is comprised of a core flange (14) which conducts the magnetic flux from the housing (3) to the pole core (4).
- the pole core and the core flange are made in one piece.
- the yoke (7) comprising the armature (5) is provided with a flange (15). equipped, which conducts the magnetic flux from the housing (3) to the armature (5).
- the flange and the yoke are two parts through
- an end plate (12) is welded, which serves the anchor (5) as a stop and a hole or a plurality of holes (13).
- the end plate (12) is joined by pressing into the yoke (7).
- the housing (3) comprises the magnetic coil (2) and the yoke (7).
