Abstract

An electrodynamic actuator, in particular for a microvalve or a micropump, includes a magnet arrangement for generating a magnetic field and a control element movable relative to the magnet arrangement. The control element includes an energizable air-core coil (22) which is arranged in the magnetic field and firmly coupled to a coil carrier (20) made from a nonmagnetic material.
