US Patent 11908649 Actuator with Thomson coils

An actuator, which is a part of a combination that includes a pair of circuit interrupters, advantageously employs a plurality of Thomson coils that are electrically connected in parallel and that interact with a corresponding set of Thomson plates of a rotatable armature in order to perform useful work in a rapid fashion. In one embodiment, the useful work is to commutate current from one circuit interrupter to the other.
