发明名称 Position recognition in an electromagnetic actuator without sensors
摘要 An electromagnetic actuator and a method for controlling the actuator comprising at least one armature (3) and two coils (1, 2). The voltage gradient at the two coils (1, 2) is measured during a sudden increase in voltage. From this measured data, a subtractor (16) computes a third voltage gradient (25) from which a logic unit (17) determines the position of the armature (3) without the use of an additional sensor.
