Electric linear motor, in particular the design of the primary part and a method of manufacturing the primary part

Abstract

A primary part of a linear motor has a terminal compartment at the end of the linear motor for connecting motor windings to feeder cables, with the walls of the terminal compartment being formed from an electric casting compound, and terminal elements being embedded in the casting compound of the terminal compartment, where the terminal elements can be connected to feeder cables. Dividing webs which are also made of the casting compound may extend between the terminal elements in the terminal compartment. To manufacture the primary part, a die having a complementary shape to the terminal compartment to be formed is introduced into a housing before casting and the terminal elements are attached to the die before casting. After casting and curing of the casting compound, the die is removed. The resulting terminal compartment can be closed by a cover through which the feeder cables pass and which functions as a cable grip for the feeder cables.
