An armature for an electromagnetic actuator, the armature including an armature body, at least one electrically conductive member configured for cooperation with a magnetic field generator of an electromagnetic actuator, and a connection end configured for connection of the armature to an apparatus operable by an electromagnetic actuator. The armature body also having a cellular structure. The armature may form part of an electromagnetic actuator, which in turn may be a component in a switch device. The armature may be manufactured by an additive manufacturing process.

A system for wireless power transfer having a power transfer device, including a capacitor unit and an inductor unit connected in series to form an LC resonant circuit. The inductor unit is designed to form an envelope with a toroidal shape, the envelope forming an inductor coil with at least one turn, which generates an oscillating magnetic field outside of the envelope used for the wireless power transfer. The ends of each turn are electrically insulated from each other by means of an insulation gap, and appropriately connected by wires inside the envelope. The capacitor unit is disposed inside this envelope such that the envelope wraps the capacitor unit and wires between the capacitor unit and the inductor unit.

An actuator for a mechanical switch, a mechanical switch, a circuit breaker and a high voltage power transmission system including such an actuator are disclosed. The actuator includes at least one armature and a first primary coil with turns wound around a central coil axis, where the armature is movable along the central coil axis and there is a magnetic flux concentrator provided at least around the first primary coil.

An actuator system for actuating a high voltage current interrupter is disclosed. The actuator system comprises a transmission link for transmitting kinetic energy from a force provision system to a moveable contact of the current interrupter. The transmission link has a first end which is mechanically connectable to the moveable contact of the current interrupter and a second end facing away from the moveable contact. The actuator system further comprises a damping system comprising a shock-absorbing mass. The shock-absorbing mass is located along the extension of the line of translational movement of the transmission link, at the farther side of the transmission link as seen from the current interrupter, so that upon an opening operation of the current interrupter, the second end of the transmission link will collide with the shock-absorbing mass.
