Abstract
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.
