Abstract
The invention relates to a secondary part for a linear motor, comprising several permanent magnets (3) which are juxtaposed and embedded in a cast body (5) of plastic compound on a carrier plate (1). According to the invention, longitudinal grooves are provided alongside the juxtaposed permanent magnets (3) in the cast body (5) to receive cooling pipes (9). The grooves are preferably configured as undercut grooves and form locking means for securing the cooling pipes (9). The inventive measures are particularly useful for forming secondary parts from several juxtaposed secondary part elements, whereby single-piece cooling pipes can be used for all of the segments.
