Abstract
A linear motor having a fixed inductor and a moving part including windings and a stator. The stator includes a plurality of teeth defining a plurality of slots into which the windings are inserted, the stator being segmented into a first piece and a second piece adjacent to the first piece. A joint is defined between the first piece and the second piece. A fastening fastens the first piece to the second piece, wherein the fastening includes a recess disposed in a first lateral surface of the first piece located at the joint, wherein the recess opens exclusively onto the lateral surface and defines at least one locking surface. A complementary part formed from the second piece and which engages the at least one locking surface so as to hold the first lateral surface and a second lateral surface of the second piece against one another.
