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 new method for manufacturing a ferromagnetic part for an electromagnetic contactor, the ferromagnetic part having both particularly high impact mechanical durability, good ferromagnetic properties and good corrosion resistance, while integrating a non-magnetic gap. The method includes the following successive steps: a step a) of supplying a soft ferromagnetic metal blank part; and a step b) of electroless nickel plating at least one section of the blank part in order to obtain the ferromagnetic part, the section of which is surface coated with a nickel surface layer, with the obtained ferromagnetic part including the soft ferromagnetic metal, which, for at least one electroless nickel plated section, is disposed under the nickel surface layer.

摘要： A mobile part of an electromagnetic actuator for an electric contactor. The mobile part is made up of a flat piece cut from a rolled sheet. This flat piece includes a first stage intended to face towards a fixed part of the actuator and a second stage, side-by-side with the first stage along an axis of movement of the mobile part. A solid section of the second stage, measured in a plane perpendicular to the axis of movement of the mobile part, is smaller than a solid section of the first stage.
