Magnet system for an electrical actuator
View Patent ↗A magnet system for an electrical actuator includes a substantially U-shaped magnet yoke having substantially parallel first and second pole legs connected by a yoke web. The first pole leg has a longitudinal end section bent out of a plane of the first pole leg. A longitudinal side of the longitudinal end section forms a first magnet pole. The second pole leg has an end face forming a second magnet pole.
1. A magnet system for an electrical actuator, comprising:
a substantially U-shaped magnet yoke having substantially parallel first and second pole legs connected by a yoke web;
the first pole leg having a longitudinal end section bent out of a plane of the first pole leg, the first pole leg having a widened region extending from a substantially center region of the first pole leg through the longitudinal end section, a longitudinal side of the longitudinal end section forming a first magnet pole;
and the second pole leg having an end face forming a second magnet pole;
wherein the first pole leg is a yoke leg and the second pole is a core leg, the core leg being provided with a coil body.
2. The magnet system of claim 1 , wherein the longitudinal end section extends substantially perpendicular to the first pole leg.
3. The magnet system of claim 1 , further comprising an armature that pivots between an open position and a closed position, the armature contacting at least the first magnet pole in the closed position.
4. The magnet system of claim 3 , wherein an elongated, plate-shaped, and substantially flat hinged armature is sized to be substantially similar to the first magnet pole.
5. The magnet system of claim 1 , wherein the first and second magnet poles are in the same plane.
6. The magnet system of claim 1 , wherein the first magnet pole has a larger contact area than the second magnet pole.
7. The magnet system of claim 1 , wherein the second pole leg and the yoke web have the same cross-sectional area.
8. The magnet system of claim 1 , wherein the longitudinal end section extends toward the second pole leg.
9. The magnet system of claim 8 , wherein the height of the yoke web is sized to accommodate the longitudinal end section between the first and second pole legs.
10. The magnet system of claim 9 , wherein a space is formed between the coil body and the yoke leg.
11. The magnet system of claim 1 , wherein the longitudinal end section extends away from the second pole leg.
12. The magnet system of claim 1 , wherein the widened region has a recess adjacent the longitudinal end section.
13. The magnet system of claim 1 , wherein a space is located between the coil body and the first pole leg.
14. Magnet system for an electrical actuator, comprising:
a substantially U-shaped magnet yoke having a core leg extending substantially parallel to a yoke leg, the core leg and the yoke leg being connected by a yoke web;
the yoke leg having a longitudinal end section bent out of a plane of the yoke leg and extending substantially perpendicular thereto, the yoke leg having a widened region extending from a substantially center region of the yoke leg through the longitudinal end section, a longitudinal side of the longitudinal end section forming a yoke pole; and
the core leg being provided with a coil body, the core leg having an end face forming a second magnet pole.
15. The magnet system of claim 14 , further comprising an armature pivots between an open position and a closed position, the armature contacting at least the yoke pole in the closed position.
16. The magnet system of claim 15 , wherein an elongated, plate-shaped, and substantially flat hinged armature is sized to be substantially similar to the yoke pole.
17. The magnet system of claim 14 , wherein the yoke pole and the core pole are in the same plane.
18. The magnet system of claim 14 , wherein the yoke pole has a larger contact area than the core pole.
19. The magnet system of claim 14 , wherein the core leg and the yoke web have the same cross-sectional area.
20. The magnet system of claim 14 , wherein the widened region has a recess adjacent the longitudinal end section.
21. The magnet system of claim 14 , wherein the longitudinal end section extends toward the core leg.
22. The magnet system of claim 21 , wherein the height of the yoke web is sufficient to accommodate the longitudinal end section between the yoke and core legs.
23. The magnet system of claim 14 , wherein the longitudinal end section extends away from the core leg.
