Definitions
- the yoke body one Have an E cross section.
- the associated coil is then as a rectangular toroid in the two parallel ones Grooves inserted, the free ends of the yoke body form the pole face of the electromagnet.
- the invention has for its object the above To avoid disadvantages.
- a laminated Perforated body with E-cross section for an electromagnet that of two parallel, interconnected partial bodies exists, each have a U-cross section and each by a plurality of U-shaped, one inside the other inserted sheet metal strips are formed.
- the two partial bodies thus have a shell shape running in the longitudinal direction with U-section, so that by the parallel arrangement of two partial bodies the desired yoke body with E-cross section can be manufactured.
- the shell shape of the innermost sheet also results in smooth wall surfaces for the grooves for receiving of the magnetic coils, which are optimally guided in the innermost shell are.
- Another advantage of the bowl shape is that ideally transfer the bending moments that occur during operation become. As with magnetization, the magnetic lines always run along a sheet, thereby the optimized magnetic properties of the electromagnet. The The desired minimization of the eddy currents is retained.
- the U-shaped bent sheet metal strips of the partial body by gluing are firmly connected.
- the plates by soldering, by welding on the end faces or by means of a positive connection To connect punching together.
- the two sub-bodies together by a housing of the electromagnet are connected. This can be done with an appropriately designed Housing done by a pure form fit.
- the two partial bodies are bent by at least one U-shaped overlapping retaining plate are interconnected.
- the two Partial body encompassed and held together on the outer circumference, here, too, the connection via gluing or soldering or welding is also possible.
- the yoke body shown in Fig. 2 in the invention Embodiment is essentially made up of two parallel, interconnected partial bodies 6 and 7 are formed, which each have a U cross section. Every body part 6, 7 is by a plurality of U-shaped sheet metal strips 8 formed, which are arranged in a packet-like manner. The individual U-shaped sheet metal strips are glued, Welding or firmly connected to each other by soldering.
- the two partial bodies 6, 7 can also form one solid body connected by gluing or soldering be or held together positively by a housing become.
- the embodiment shown in Fig. 3 corresponds in its Basic structure of the embodiment according to FIG. 2.
- the two partial bodies 6 and 7 are the embodiment by a U-shaped bracket 9, the two part body includes and that can have a larger sheet thickness, firmly connected.
- the holding plate 9th to be provided in several layers.
- the holding plate 9 can, like the connection of the individual metal strips with each other, by gluing be connected over the entire surface.
- This electromagnetic actuator consists of essentially of two electromagnets 13, 14, each one Yoke body 15, 16, which according to the basis 2 and 3 described embodiments laminated is. There is a coil in each of the two yoke bodies 17, 18 arranged, each with one not closer here illustrated controllable power supply in connection stands. In the led through the yoke body 15, 16 Bores 11 each have a guide sleeve 19 attached.
- the two electromagnets 13, 14 are spaced apart arranged so that their pole faces 21.1 and 21.2 each other are turned.
- a plate-shaped one Anchor 22 arranged with a guide pin 23 is firmly connected.
- the guide pin 23 is in the guide sleeve 20 of the electromagnet 14 out.
- the electromagnet 13 a separate guide pin 24 is provided, the one end on the anchor-side guide pin 23 supports and with its other end over a fault plate 25 is supported on a return spring 26.
- the free end 27 of the guide bolt connected to the armature 22 23 is based on an actuator 28, for example the stem of a gas exchange valve, which has a return spring 29 is assigned.
- the two return springs 26 and 28 are designed so that when the electromagnet is de-energized 13, 14 the anchor 22 in the middle position between the two pole faces 21 is located.
- the two Yoke bodies 15 and 16 are each open to the side Housing 13.1 and 14.1 arranged, but each end, encompassing the face of the yoke body and the coil, closed is.
- the two housing parts 13.1 and 14.1 are connected to each other via a spacer frame 30, on the the continuous longitudinal edges of the two yoke bodies 15 and support 16 continuously. In connection with the support on the front ends of the spacer frame 30 results the hollow beam-like profile shape has a high level of shape.
