A stator for a motor contains a number of stator sheets stacked in a star-shaped laminated core. The stator sheets contain stator sheets closed in the circumferential direction and have single teeth connected to one another by pole shoe webs and stator sheets open in the circumferential direction and have single teeth spaced apart from one another to form a gap. A bottom starting block is adjoined by a repeat block which has N identical repeat sequences. Each repeat sequence contains n directly consecutive open stator sheets with a gap on the pole shoe side and at least one closed stator sheet. The laminated core also has a terminating block and an intermediate block between the repeat block and the terminating block. The intermediate block contains a closed stator sheet and/or a gap on the pole shoe side created by m open stator sheets, where 1≦m≦n−1.

The invention relates to an apparatus for the production of a regular microwave field over a comparatively great area. This apparatus has a cavity resonator into which microwaves are put. Electromagnetic energy is coupled by special couplers, inductively or capacitively, out of the standing waves forming in the cavity resonator into a chamber in which preferably a plasma is contained.

The invention relates to an arrangement for acoustic decoupling of a stator of an electric motor having two substantially cylindrical decoupling rings disposed on both sides of the stator and concentric to a motor shaft, each fixed to a front side of the stator on one side and each fixed to a housing enclosing the stator on the other side, and comprising recesses on the circumferential surfaces thereof. The decoupling rings hold the stator in a centered position at a distance from the housing. The recesses allow targeted acoustic decoupling. The invention is particularly applicable for electric motors in steering systems for motor vehicles.

The invention relates to a device for coupling microwave power out of a first chamber (21) into a second chamber (22). For this purpose a primary antenna (2) and a secondary antenna (3) are provided, the primary antenna (2) reaching into the first chamber (21), while the secondary antenna (3) reaches into the second chamber (22). Between the first chamber (21) and the second chamber (22) there is provided a dividing wall (20) through which a current-carrying means (11) is brought, which joins together the primary antenna (2) and the secondary antenna (3).
