Abstract
Official abstract text for this publication.
The invention relates to a novel permanent magnet electromagnetic actuator with triggering speed and drive torque improved relative to those of the prior art. The main target application is actuating an electromechanical switch-disconnector specifically for performing the operations to disconnect a mechatronic circuit-breaker for breaking high-voltage direct currents.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electromagnetic actuator (A) of the permanent magnet type comprising: a first stator part ( 1 ) formed in a first substrate ( 10 ), at least part of which has rotational symmetry with at least one plane face forming a disk defining an axis of symmetry orthogonal to the disk, and comprising a first series of permanent magnets apparent on at least the disk of the first substrate and uniformly distributed over its surface with a constant angular pitch;…
