A stator system for an electric motor has multiple coil formers and stator windings that are wound on the coil formers. The stator windings are distributed over the circumference of the stator system and are arranged to form a substantially circular stator star. A number of the stator windings are electrically insulated in the axial direction in each case by way of a phase separator. The stator windings in each case of two coil formers are electrically connected as a coil pair in an electrically conductive manner by a conductor track. The conductor track is retained by a separating web that is arranged in the axial direction above the allocated phase separator and that extends in a radial direction.

Stator system for an electric motor

A process for improving the run-in characteristics of drives having sintered bearings. The drives are subject, prior to their operational usage in repeated cycles (I; II etc.), to a loading procedure exhibiting respectively a first load (M.sub.1), with the effect of operating of the sintered bearings in the mixed friction region (MR), and a following transition to a second load (M.sub.A, with the effect of operation of the sintered bearings in the boundary friction region (GR).
