Definitions
- the invention relates to a polarized relay according to the preamble of claim 1.
- Such a relay can be used, for example, to control a commutator motor. This applies in particular when the relay has tristable behavior and the three stable states of the relay can be assigned to the motor states "at rest”, "clockwise” and "counterclockwise”.
- a polarized relay is known from DE 32 43 266 C2, which consists of two first yokes with a U-shaped cross section, facing each other with their short legs, and smaller, second yokes enclosed by them at a distance. It is between the first and the second Yokes arranged a permanent magnet with a magnetic axis running at right angles to the large surfaces of the yokes.
- the second yokes also enclose an excitation coil, which surrounds a rod-shaped armature which can be displaced in the direction of the coil axis, the two ends of which lie outside the excitation coil and are designed as plates which form between the inner surfaces of the short legs of the first yokes and the inner legs of the short legs End faces of the second yoke are displaceable.
- the armature consists of two rod halves radially divided in the middle of the excitation coil, between which a helical compression spring is arranged, the pretensioning of which is dimensioned such that the plates of the armature bear against the pole faces of the short legs of the first yokes when the excitation coil is de-energized. while in the current-carrying state of the excitation coil, depending on the direction of current flow, either one or the other plate rests on the corresponding end faces of the second yokes.
- This relay shows tristable behavior using only one excitation coil.
- this is associated with a very complex and complex construction of the relay which, in addition to the excitation coil and its two-part armature, has a compression spring, two permanent magnets and four yokes.
- the spring force of the compression spring must be overcome by the force of the magnetic field built up by the excitation coil during each switching operation, which requires correspondingly large excitation currents.
- a polarized small electrical relay is known which is designed as a double changeover relay.
- a sheet anchor and reflux elements are arranged on each of the two free ends of a coil core. The leaf anchors are held in place by permanent magnets and perform a synchronous switching process when the coil is excited.
- This double changeover relay is only intended for mono- and bistable operation. It also has the disadvantage that the construction of the reflux elements requires a great deal of soft iron in order to ensure the magnetic reflux necessary for the reliable functioning of the relay.
- the invention has for its object to provide a polarized relay of the type mentioned, which shows tristable behavior when using only one excitation coil, which is simple in construction and which triggers switching operations with the lowest possible excitation currents and thus for controlling electrical consumers and / or small mechanical, hydraulic or similar adjusting devices, in particular for controlling a commutator motor.
- the invention is based on the knowledge that a polarized relay with tristable behavior and simple construction can be created when only one excitation coil is used, if an electromagnet on the two end faces which is formed by the excitation coil and the coil core arranged therein, a permanent magnet which can be displaced along its magnetic axis is arranged, the two permanent magnets facing the end faces of the coil core with poles of the same name.
- the coil core In the de-energized state, the coil core is magnetically polarized by the permanent magnets in such a way that there is an attractive interaction between the coil core and each of the two permanent magnets.
- the two permanent magnets with their identical poles facing the coil core each rest on an end face of the coil core, if not by using spacers or the like, a distance between the electromagnet and the two permanent magnets is forced.
- an attractive magnetic force acts on one of the two permanent magnets and a repulsive magnetic force on the other. The latter is brought to a greater distance from the coil core by the repulsive magnetic force.
- the relay exhibits tristable behavior. This is achieved by using only one electromagnet and two permanent magnets, with only small forces having to be overcome during the switching operations, since the position of the two permanent magnets is determined exclusively by the acting magnetic forces. There are no spring forces or the like.
- the polarized relay according to the invention is therefore suitable for triggering switching processes with low excitation currents, in particular for controlling electrical consumers, and also small mechanical, hydraulic or similar actuating devices.
- a preferred embodiment of the invention is characterized in that, when the excitation coil is de-energized, the two permanent magnets each abut one end face of the coil core and, when the coil is energized with a direct current of a predetermined strength, depending on its direction, one of the permanent magnets is at a predetermined distance can be brought from the coil core.
- the switching operations can be carried out with particularly small magnetic forces, since the permanent magnets are located in the immediate vicinity of the electromagnet and, in the de-energized state, even rest against the end faces thereof. To ensure a safe switching process, the permanent magnets and the excitation currents must be matched to one another.
- a holding plate for the relay contacts is provided on the ends of the permanent magnets facing away from the coil core.
- the relay is preferably designed such that the relay contacts attached to the holding plates of the permanent magnets are switched to identical first potentials when the excitation coil is de-energized and that when the excitation coil is energized with a direct current, The direction of which one of the relay contacts can be switched to another, second potential by magnetic repulsion of the associated permanent magnet.
- the excitation coil is wound on a base body in which the coil core is arranged in a stationary manner and in which the two end faces of the coil core each Permanent magnet opposes, which is displaceable in guides of the base body along its magnetic axis.
- the polarized relay according to the invention can be used in particular for the control device of a commutator motor with a printed circuit board on which control electronics, the brushes of a commutator motor and the polarized relay are arranged.
- This control device for a commutator motor is characterized in particular by the simple construction and the small space requirement of the polarized relay, which controls the energization of the commutator motor with only one excitation coil. Due to the compact design of the relay, the control electronics for the motor, the polarized relay and the brushes of the commutator motor can be arranged on a circuit board to save space. This also leads to a reduction in manufacturing costs.
- EP 0 474 904 A1 generally discloses a commutator gear drive unit in which an IC module, two motor relays and the brushes of the commutator motor are arranged on a printed circuit board, but this arrangement is particularly due to the use of two Motor relays are considerably more complex and require less space than the present control device for a commutator motor.
- the device according to the invention has the essential advantage over the prior art that the control device for the commutator motor as a whole can be manufactured much more cost-effectively and requires less space due to the particularly simple and compact design of the polarized relay.
- the necessary contact between the brushes of the commutator motor arranged on the circuit board and the commutator is made possible, for example, by the circuit board having a recess in which the commutator is arranged and into which the brushes of the commutator motor protrude.
- the brushes can be pressed against the commutator with compression springs.
- a particularly compact arrangement of the control for a commutator motor on a printed circuit board is possible if the polarized relay is arranged directly next to the brushes of the commutator motor.
- the design of the polarized relay is adapted to the course of the wall of the recess for the commutator in such a way that the outer contour of the relay runs at least in one section along the wall of the recess.
- the simple structure of the relay according to the invention makes this possible even with a suitable design of its components (in particular the base body and coil core) even if the wall of the recess has a curvature in said section.
- Figure 1 - a longitudinal section through a polarized relay according to the invention with de-energized excitation coil.
- FIG. 2 shows the polarized relay according to FIG. 1 with an excitation coil through which an excitation current flows in a first direction;
- FIG. 4 shows a control device for a commutator motor arranged on a printed circuit board with a polarized relay arranged in the vicinity of the brushes.
- Fig. 1 shows an embodiment of the polarized relay according to the invention.
- An excitation coil 2 is wound on a base body 1, in which a soft iron core 3 is arranged in a stationary manner as the coil core. The excitation coil 2 and the coil core 3 thus form an electromagnet.
- a permanent magnet 4 and 5 is mounted in guides 12 and 13 of the base body 1 along its magnetic axis (A) so as to be displaceable.
- the permanent magnets 4 and 5 each face one end face 31 or 32 of the coil core 3 with poles (N) of the same name.
- a holding plate 6, 7 for the two-part relay contacts 8, 9 is fastened to the ends (south poles S) of the permanent magnets 4, 5 facing away from the coil core 3.
- the relay contacts 8, 9 can be conductively connected, for example, to the brushes of a commutator motor via flexible copper strands 10, 11.
- FIG. 2 and FIG. 3 likewise show the exemplary embodiment of a polarized relay according to FIG. 1, but the connections 20, 21 of the excitation coil 2 are now at different potentials and a direct current flows through the excitation coil 2. Since the structure of the polarized relay has already been described in detail with reference to FIG. 1, only some of the components of the polarized relay are provided with reference numerals in FIGS. 2 and 3 for the sake of clarity.
- terminal 20 of excitation coil 2 is at negative (-) and terminal 21 at positive potential (+).
- a current then flows through the excitation coil 2 such that the end face 31 of the coil core acts as the north pole (N), while a south pole (S) forms on the other end face 32.
- both permanent magnets 4, 5 face the coil core 3 with their north pole (N), this means that the permanent magnet 4 is repelled by the end face 31 of the coil core 3.
- the permanent magnet 5 remains in its position and its position is stabilized by a greater attractive force.
- the relay contact 8 comes into contact with the load contact 22 and is accordingly switched to a positive potential (+).
- the relay contact 9 remains at its negative potential (-).
- the voltage opposite to FIG. 2 is applied to the connections 20, 21 of the excitation coil 2.
- a current then flows through the excitation coil 2 such that the end face 31 of the coil core functions as the south pole (S), while a north pole (N) forms on the other end face 32.
- S south pole
- N north pole
- the permanent magnet 5 is repelled from the end face 32 of the coil core 3.
- the relay contact 9 comes into contact with the load contact 25 and is switched to a positive potential (+).
- the relay contact 8 is switched to a negative potential (-), since the permanent magnet 4 is magnetically attracted by the coil core 3 and therefore bears with its north pole (N) on the end face 31 of the coil core 3.
- FIG. 4 shows the control device of a commutator motor, in which a polarized relay 100 is used to control the motor, and the components thereof in a space-saving manner are arranged on a circuit board 50.
- This compact design is made possible primarily by the particularly simple design of the polarized relay.
- the circuit board 50 which is approximately twice as long as it is wide, essentially breaks down in its longitudinal direction into two sections, one of which has the control electronics 50 and the other with the brushes 52, 53 of the commutator motor and the polarized relay 100 whose help controls the energization of the brushes 52, 53 is provided.
- the control electronics 51 comprise, for example, a microprocessor ( ⁇ C) 61 and an application-specific integrated circuit (ASIC) 62.
- the brushes 52, 53 of the commutator motor are fastened to brush holders 58, 59 and protrude into a recess 57 in the circuit board 50 through which the commutator 56 of a commutator motor is guided. With the aid of compression springs 54, 55, the brushes 52, 53 are pressed resiliently against the commutator 56.
- control and power section reduces the risk of interference which can be caused by electromagnetic fields and thus increases the electromagnetic compatibility of the system.
- the brushes 52, 53 are connected via flexible copper strands 10, 11 to the relay contacts 8, 9 fastened to the holding plates 6, 7.
- the polarized relay 100 is arranged directly adjacent to the recess 57 next to the commutator 56 and has the same principle Structure and the same mode of operation as the relay described above with reference to Figures 1 to 3.
- the relay 100 differs from that described with reference to FIGS. 1 to 3 only in that the base body 1, on which the excitation coil 2 is wound, and the coil core 3 have a curved shape such that the outer one adjacent to the recess 57
- the contour of the relay 100 extends at least in one section along the curved wall of the recess 57. Because of its simple construction and suitable shaping of the few components from which it consists, the relay can also be easily adapted to other spatial requirements, for example a rounded end section 65 of the printed circuit board 50.
- the very compact design of the control device for the commutator motor is achieved primarily by the fact that the polarized relay, with the aid of which the commutator motor is controlled, only comprises an excitation coil, a coil core and two permanent magnets, once the relay contacts and similar very small components.
- the control device therefore enables significant space and cost savings compared to the prior art, according to which two relays for controlling a commutator motor are arranged on a circuit board.
- the function of the relay 100 in controlling the energization of the brushes 52, 53 and thus the direction of rotation of the motor need not be explained again here, since it has already been shown in detail above with reference to FIGS. 1 to 3.
- the control electronics 51 are used to control the input voltage at the excitation coil 2, by means of which the switching processes in the polarized relay 100 are triggered.
- the scope of the invention is not limited to the exemplary embodiments shown, but can also be used as a control, actuating and drive device for small mechanical, electromechanical, hydraulic, pneumatic or similar actuating devices.
