Abstract
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.
Claims17
An armature for an electromagnetic actuator, the armature comprising:
- an armature body comprising a cellular structure,
- a magnetic field generator including a repulsion coil,
- at least one electrically conductive member configured for cooperation with the magnetic field generator,
- a connection end configured for connection of the armature to an apparatus operable by an electromagnetic actuator,
- wherein the electrically conductive member is a separate member attached to the armature body,
- wherein the armature body comprises a connection part configured as a channel in the armature body and said channel having an opening at the connection end of the armature, wherein the connection part is configured for connection of the armature to the apparatus operable by the electromagnetic actuator, and wherein said channel has a channel wall that forms part of an armature housing.
