Tooth module for primary components of permanent magnet synchronous motors

The invention relates to a tooth module (6) for primary parts (12) of permanent magnet synchronous motors (7, 8, 13) having at least one at least partly permanent-magnet-free secondary part (9), wherein the secondary part (9) consists of an iron structure, with the primary part is constructed (12) facing the teeth (11), wherein the tooth module (6) at least one permanent magnet (1, 14) and on opposite sides of each at least one iron yoke (2), wherein between the iron bars (2) of a side cut-outs (3 ) exist and the iron bars (2) at least one coil (5) is guided, at least on one side of a tooth module (6) comprises a further tooth module (6) can be fastened, so that the iron webs (2) each (in the recesses 3 access) of the adjacent tooth module (6) and the tooth modules (6) at different predetermined primary parts (12) are joined together.
