Abstract: 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.

Abstract: The present invention relates to a permanent-magnet synchronous motor, particularly an electric three-phase motor, comprising a stator having a stator yoke in which stator teeth with interposed stator grooves are arranged, wherein on each stator tooth at least one winding is provided, further comprising a rotor having permanent magnets, wherein the stator teeth are arranged in layers as disks in the axial direction of the stator and designed at least as two different disks, wherein the stator teeth in a first disk are connected peripherally among each other at the ends thereof pointing toward the rotor in the form of a stator star by a connecting bridge and in a second disk have an interruption instead of the connecting bridge. The present invention further relates to an electric power-assisted steering system.

Abstract: Despite the axial sandwich assembly of the motor housing (1), pump housing (2) and electronics housing (3), it is possible by using simple manufacturing and assembly techniques to provide a plug connection, which is free from distortions and resistant to breaking, with supply lines and control lines (4.1; 4.2) that start from a brush plate (6) inside the motor housing (1) and pass through the pump housing (2) up to the electronics housing (3). To this end, the supply and control lines (4.1; 4.2) are fastened in the manner of a fixed plug via their ends, which are located on the motor housing, as a pre-assembled component to a fastening flange (6.2) that radially projects above the motor housing (1). The fastening flange (6.2), in the plugging direction counter to its plug connection with the electronics housing (3), can be supported via at least one supporting rib (6.1) on the outer periphery of the motor housing (1).

Abstract: A driven-side rotor shaft end of an electric motor is drive-connected to a drive-side pump shaft end of a pump via a coupling piece, in the manner of a cardan joint, in each case by means of the positive axial plug receptacle. The invention provides protection against torsional thrusts and axial vibrations, and a play-free drive by virtue of a conical design of the plug receptacle, at the same time with a mutual axial prestress of the rotor shaft end and pump shaft end.

Abstract: 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).
