The present disclosure is, inter alia, concerned with a linear motor having an armature mounted for driven linear oscillation essentially along a longitudinal direction, a secondary mass mounted for linear oscillation essentially along the longitudinal direction, and a coupling unit for coupling the armature and the secondary mass, wherein the coupling unit comprises at least two coupling spring assemblies and at least a coupling element, the coupling spring assemblies being arranged in planes perpendicular to the longitudinal direction and being spaced apart from each other, and the coupling element being fixedly connected with the coupling spring assemblies.
