Definitions

  • the first and second electromagnet are arranged in a housing at a predetermined distance.
  • An armature plate is movably arranged between the first and second electromagnets and is biased into a predetermined rest position by a first and a second spring.
  • the anchor plate is rigidly connected to a shaft of the gas exchange valve. In order to bring the armature plate into contact with the first electromagnet from its rest position, the first coil is excited with a pull-in current. The pull-in current causes an electromagnetic force that the
  • the invention is solved by the features of the independent claims.
  • the solution has the advantage that the catching current can be set low. This keeps the losses in the first and second electromagnets low and prevents excessive heating of the electromagnet, which can lead to thermal destruction of the electromagnet.
  • Another advantage is that reliable control is also ensured if disturbing forces act on the actuator. Such disturbing forces can be caused, for example, by strong vibrations.
  • the method for controlling the actuator is described with reference to FIGS. 2 and 3. It is irrelevant to the invention whether the method is executed in the form of a program in a microprocessor or whether a corresponding circuit arrangement is provided for this.
  • the procedure can also be carried out in the form of one computing process or in the form of several computing processes.
  • the catch current I_F, the holding current I_H and the starting current I_A can alternatively also be corrected multiplicatively.
  • the setpoint I_SP1 for the current through the first coil 113 is the capture current I F.
  • the armature plate 117 arrives System with the first core 112.
  • the setpoint I_SP1 of the current through the coil is the holding current I_H.
  • the time t 3 is preferably chosen so that it is as close as possible to the time t 2 .
  • the impact of the anchor plate 117 is preferably determined by evaluating the position X. In a simple embodiment, the time interval between the times ti and t 3 can, however, also be determined experimentally and be a fixed, predetermined value.
  • the actuator can also be designed as an injection valve.
  • the method can be executed as a program by a microprocessor. However, it can also be implemented by a logic circuit or an analog circuit arrangement.
  • the controller can also be designed, for example, as a single-point controller with a timing element or as a pulse width modulation controller.

Abstract

Selon l'invention, un appareil de réglage électromécanique comprend un organe de réglage et un servomoteur. Le servomoteur comporte un premier électroaimant (112) et un second électroaimant (114), placé à une distance prédéterminée du premier électroaimant. Le servomoteur comporte en outre une plaque d'induit (117) mobile, un premier et un second ressort (118a, 118b) qui exercent un précontrainte sur la plaque d'induit pour la maintenir dans une position de repos (R) prédéterminée. Un capteur de position (5) détecte la position (X) de la plaque d'induit (117). Les électroaimants sont alimentés de façon alternée en un courant de blocage prédéterminé (I_F). Ce courant d'arrêt est augmenté lorsque la plaque d'induit reste en position de repos (R) plus longtemps qu'une période prédéterminée (T_DIAG).
