ABSTRACT:
The invention relates to a secondary part (2, 3) of a linear electrical machine (5), wherein the secondary part (2, 3) has permanent magnets (11) and a mount (13). The secondary part (2, 3) has spacer elements (9), wherein an installation height of the secondary part (2, 3) is also determined by means of the spacer elements (9). Tolerances of the installation height can be maintained more easily by means of the spacer elements. In a method for manufacturing a secondary part (2, 3) of a linear electrical machine (5), the spacer elements (9) are cast together with the mount (13) on which the permanent magnets (9) are arranged such that the permanent magnets (9) are embedded in the casting compound (15) and the casting compound (15) forms the surface of the secondary part (2, 3) in the region of the permanent magnets (11), wherein the spacer elements (9) protrude out of the casting compound (15) such that part of the surface of the secondary part (2, 3) is also formed by the spacer elements (9).
