Abstract
The invention relates to a primary component (2) for a linear motor (1), wherein the primary component (2) comprises at least one laminated core (6). A first means (4) for creating a first magnetic field is arranged in the grooves (17) of the laminated core (6). A second means (5) for creating a second magnetic field is arranged on the teeth (9) of the laminated core (6). The primary component (2) is provided for arrangement with a secondary component (3), and the primary component (2) and the secondary component (3) are spaced from each other by an air gap (13). The primary component (2) comprises a flat cover (15), arranged on the side of the primary component (2) facing the air gap (13).

-14. (canceled)
A primary part for a linear motor, said primary part comprising:
- at least one laminated core;
- a first means arranged in slots of the laminated core to produce a first magnetic field;
- a second means arranged on teeth of the laminated core to produce a second magnetic field, said second means having at least one permanent magnet;
- and
- a flat cover arranged on a side of the primary part in confronting relationship to an air gap by which the primary part is separated from a secondary part.
A linear motor, comprising:
- a primary part having first and second means for production of magnetic fields, with one of the first and second means having at least one permanent magnet;
- and
- a secondary part separated from the primary part by an air gap and constructed in the absence of producing a magnetic fields,
- said primary part having a cover arranged on a side of the primary part in confronting relationship to the air gap.
