Abstract: A secondary part provides a magnetic path for a primary part of a linear motor and includes a spacer element as well as yoke plates forming two limbs, which are arranged for an attachment to the spacer element so that—situated opposite each other—they extend in planes parallel to the magnetic path. In addition, the secondary part includes a plurality of permanent magnets, which are fixed in place on inner sides of the yoke plates pointing toward the magnetic path. The permanent magnets each have a width that decreases in an extension direction perpendicular to the magnetic path.

Abstract: A segmented secondary part of a linear motor includes at least two segments, each having a plurality of magnets attached to a yoke plate, having alternating polarity, and having a direction of magnetization perpendicular to the yoke plate. The yoke plates include an overlapping region, in which the yoke plates of adjacent segments are superposed in the direction of magnetization but do not touch each other in the overlapping region.

Abstract: A cold plate for a linear motor includes a planar housing having a cooled surface for placement against a surface to be cooled, and first and second chambers arranged in the housing, which extend parallel to the cooled surface and are separated by a diaphragm. The housing has two half-shells and the diaphragm, which is disposed between the half-shells and is connected to the two half-shells. The first chamber, facing away from the cooled surface, is connected to a coolant inlet, and the second chamber, bounded by the cooled surface, is connected to a coolant outlet.

Abstract: A primary element of an ironless linear motor include cooling plates. Each of the cooling plates is connected to a connecting piece extending in a region of an edge of the cooling plate. The connecting pieces are configured to supply coolant. The connecting pieces are located one above the other in a direction perpendicular to the cooling plates so as to form a common connecting region of the cooling plates at an end face of the primary element. A plurality of coils are disposed between the cooling plates. A coolant distribution header is releasably attached to the connecting region.

Abstract: A coil arrangement for an electric motor includes a plurality of individual coils and a plurality of housing modules. Each of the housing modules is a plastics part that is separately produced from the coil arrangement. Each of the housing modules is designed to enclose the same amount of the individual coils.
