Abstract

A secondary part of a linear motor, for use in an elevator installation, includes a frame having a plurality of free spaces formed therein, each of the free spaces being surrounded by an inner surface of the frame, at least one magnet positioned in an associated one of each of the free spaces, each magnet having at least one end face spaced from the inner surface, and an adhesive material filling a space between the end surface and the inner surface wherein the magnet is selectively positionable in the associated free space prior to gluing of the magnet to the frame by the adhesive material. The secondary part can be used in a linear motor having: a first primary part, a further part being one of a secondary primary part and an iron element, and the secondary part disposed between the first primary part and the further part. A method of producing the secondary part involves forming a frame having a plurality of free spaces therein, each of the free spaces being surrounded by an inner surface of the frame, positioning at least one magnet in an associated one of each of the free spaces, the magnets being sized smaller than the associated free spaces to provide a space between a side surface of each magnet and the inner surface surrounding the associated free space, and filling the space with an adhesive material to glue each magnet to the frame.
