Abstract
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.

An electromagnetic actuator for an electric contactor, comprising:
- a fixed part;
- and
- a mobile part, wherein:
- the mobile part is made up of a flat piece, cut from a rolled sheet,
- the mobile part in the form of the 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,
- the fixed part includes two cores around which coils are wound, and
- the mobile part in the form of the flat piece includes at least one magnetic flux concentrator, and each magnetic flux concentrator is arranged so as to be opposite one of the cores of the fixed part.
An electromagnetic actuator comprising:
- a fixed part;
- and
- a mobile part, the mobile part being made up of a flat piece, cut from a rolled sheet,
- wherein the mobile part in the form of the flat piece includes:
