  • Publication number: 20090070575
    Abstract: The aim of the invention is to improve the start-up of an electrical machine drive control system comprised of at least one machine (80) and of at least one machine control (100; 90, 95). The start-up should proceed in such a manner that, during servicing, a quicker and more reliable device exchange is made possible. Methods are provided for starting up as the first or new start-up. A boot memory area (50) for storing machine-related data is provided that comprise at least a number of first parameters for a number of controllers (12) and a number of user-specific second parameters of the drive control system. The first and second parameters are permanently stored in the boot memory area. The storage area (50) is organized on a module, which can be removed from and inserted once again into the machine control (100; 90, 95). A transmission of all machine-related data ensues from the b boot memory area (50) of the module to the machine control (95).

  • Patent number: 7045925
    Abstract: A stator for an electric rotating-field induction generator that is much simpler to produce, especially regarding its windings, includes main and auxiliary poles projecting inward pressed or otherwise disposed radially onto the inner side of a yoke and positioned alternately about the circumference, of which the auxiliary poles are not wound, and the main poles are each surrounded by a coil. Each of the wound poles has a groove in the direction of the longitudinal side parallel to the axis along its longitudinal sides to accept coil sections, and these grooves include a trapezoidal cross-section and are enclosed by the non-wound auxiliary poles at the longitudinal-side groove opening.
