Electrical machine dynamics continued,ion, the magnitude, nature, and duration of the disturbing forces, and the calculation of the dynamical response. It is thus necessary to have detailed information about the parameters of the machine and the nature of nonlinear functions and saturation effects associated with them.

Virtuelle Organisationen als Konzeptes developed very rapidly. By the beginning of the twentieth century, industry was using machines which were efficient, mechanically strong, and beautifully made—indeed many of these machines are still in excellent working condition. For about twenty years from 1900, much research and development we

We shall, however, refer to these rotating electromechanical energy converters simply as electrical machines.

Grundzüge der Kulturpsychopathologieeloped in the previous chapter leads to more exact solutions and will be used later, in the form of generalised machine theory. There is, however, the danger that by formulating equations in a ‘mechanical manner’ and solving them by using a digital computer, one may lose sight of the physical proces

Die Persistenz sozialer Kontinuanten,ertia constants. In a mechanical system damping and spring constants can be easily visualised—damping, for instance arises due to friction. In an electrical system, mechanical friction constitutes a small part of the total damping, the main damping torque being of electrical origin. In trying to und
