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.

Armature for electromagnetic actuator, an electromagnetic actuator, a switch device and a method for manufacturing an armature

An electrical machine with a rotor or the stator including a plurality of discrete field modules, and the other one of the rotor and the stator including a plurality of armature coils connected to different power converters. Each field module includes one or more field coils which can be activated independent of the field coils of the neighbouring field modules. When at least one of the field coils is inactivated, e.g. because of a defect, each of the power converters is allowing less power to pass through when an armature coil connected to it is moving over an inactivated field coil, and more power to pass through when the armature coil connected to it is moving over an activated field coil.
