The adsorption bar includes an electromagnetic component and an adsorption member. The electromagnetic component includes a slide bar, a coil and a movable part. The coil is fixedly arranged on the slide bar. The movable part includes an elastic element and a magnet. One end of the elastic element is a fixed end which is fixedly connected to the slide bar, and the other end thereof is a free end which is connected to the magnet. The adsorption member is fixedly connected to the magnet and is exposed at one end, of the magnet, away from the coil. Current is applied to the coil to generate a magnetic field. The magnet longitudinally slides along the slide bar under a repulsive force of the magnetic field.

摘要： A method is provided for controlling an actuator comprising an electromagnet and a control device, the electromagnet including a coil and a moving part that moves between a first position and a second position, the control device including a power supply member configured to supply the coil with an electric current having a voltage and an amperage and a measurement member for measuring a value of a quantity from among the voltage and the amperage. The method includes acquiring samples of the measured value, of regulating, according to a proportional-integral-derivative algorithm, the electric current to around a setpoint value that is equal to a maintenance value capable of maintaining the moving part in the second position, of comparing each sample to a predetermined threshold and of detecting a movement of the moving part if a single sample is above or equal to the threshold.

摘要： A method includes driving a component in an electromagnetic actuator back and forth during one or more cycles of the actuator, where the actuator includes a voice coil. The method also includes identifying a back electromotive force (EMF) voltage of the voice coil during at least one of the one or more cycles. The method further includes determining whether a stroke of the component is substantially centered using the back EMF voltage of the voice coil. In addition, the method includes, based on the determination, adjusting one or more drive signals for the voice coil during one or more additional cycles of the actuator. Determining whether the stroke of the component is centered could include determining whether the back EMF voltage of the voice coil is substantially maximized or determining whether times between extremes in the back EMF voltage are substantially equal.

摘要： An amperage control for an electrically operated valve having a coil. A process control apparatus generates a plurality of electrical operating data signals, each signal corresponding to an operating parameter of the valve. A valve control apparatus transmits voltage to the coil of the valve to control the operation of the valve, the valve control apparatus receiving at least one operating data signal generated by the process control apparatus. A current flow is created in the coil of the valve upon receiving voltage from the valve control apparatus. A current senses the flow of current in the electrically controlled valve, and creates an electrical signal responsive to the current flow in the coil of the valve. When the signal created by the current sensing apparatus is applied to the valve control apparatus, the valve control apparatus modifies the operation of the valve responsive to the signal created by the current sensing apparatus.

摘要： An electromagnetic actuator includes a stator assembly mounted to a center pole formed of material having high magnetic permeability and functions as a return path for the magnetic field generated when current is passed through coils in the stator assembly. When current is applied to one or more coils within the stator assembly, a magnetic field is generated that interacts with a magnetic field generated by one or more magnets disposed within the armature assembly and causes the armature to move relative to the center pole thus, for example, opening or closing a valve.
