Abstract
An electric linear motor includes a rotor as primary; and a secondary which is spaced from the rotor to define an air gap therebetween for interaction between the rotor and the secondary. The secondary has a carrier with electrically and/or magnetic driving elements, a cover for protection of the carrier against contamination or damage, and a support unit which supports the cover for movement relative to the carrier. Thus, contaminated regions of the cover can be removed from the surface of the secondary and cleaned by a wiper element.
