Abstract

A primary component for a linear motor includes at least one laminated core. A winding for creating a first magnetic field is arranged in the grooves of the laminated core. Permanent magnets create a second magnetic field and are arranged on the teeth of the laminated core. The primary component is provided for arrangement with a secondary component, and the primary component and the secondary component are spaced from each other by an air gap. The primary component includes a flat cover, arranged on the side of the primary component facing the air gap.
