One of the components has at least three phases (4-6), each with at least one phase winding (1-3), which in drive feeds alternating voltage. During drive, the phase windings are symmetrically coupled to one another in accordance with a specific configuration. - The machine has components (7-11) which during operation change over the phase windings from a first to a second configuration. A device is also incorporated for controlling the changeover components. This device in several stages controls different changeover components so that they successively uncouple the phase windings from one another within the first configuration and successively couple them together again by a different method to a second configuration, so that the coupling together to the new second configuration, so that the coupling together to the new second configuration is commenced before all phase windings have been uncoupled from one another within the first configuration. This permits an intermediate temporary operation with asymmetrical phase winding configuration before achieving the second configuration. |
