Embodiment Construction

[0042] According to the figure 1 with 2In the preferred embodiment of the present invention, the electromagnetic actuator 100 includes a movable armature 12 and a fixed yoke 11 . The movable armature 12 and the fixed yoke 11 thus form a deformable magnetic circuit 1 with an air gap. As an exemplary embodiment, the movable armature 12 is fitted in the fixed yoke 11 . The movable armature 12 is mounted to slide axially along the longitudinal axis Y of the fixed yoke 11 .

[0043] The movable armature 12 moves between an open position K1 and a closed position K2. As an example of operations such as figure 2 The closed position K2 shown generally corresponds to the smallest air gap existing between the movable armature 12 and the fixed yoke 11, and the open position corresponds to the largest air gap.

[0044] The electromagnetic actuator 100 also includes an excitation coil 3 in which an excitation current I can flow. The field coil 3 is then used to generate a magnetic f...

Abstract

A processing unit has control units (21) acting on an excitation coil (3) to displace a mobile armature (12) of an electromagnetic actuator (100) and generating a periodical voltage wave frame including at least n rectifying alternation. Each alternation includes at least one first impulsive excitation order starting at a zero voltage of the alternation, and at least one second impulsive excitation order terminating at a zero voltage of the alternation. Electrical energy of the orders of the first alternation is lower than or equal to an electrical energy of the orders of the second alternation posterior to the first alternation.

Description

technical field [0001] The invention relates to a processing unit comprising control means designed to act on at least one field coil to move a movable armature of an electromagnetic actuator, said control means generating a periodic voltage comprising at least n commutation half-cycles (alternations) wave frame. [0002] The invention also relates to an electromagnetic actuator comprising such a processing unit. Background technique [0003] The function of an electromagnetic actuator is to convert electrical power into mechanical energy. Mechanical energy is used to move a mechanical load. Movement of mechanical loads is generally achieved by opposing forces called load forces. [0004] The operation of the electromagnetic actuator is related to its use conditions. Certain ambient conditions depend in particular on the nature and / or number of devices to be actuated. Other ambient conditions depend on the temperature at which the actuator is used. Finally, the operati...
