摘要

The machine has a stator (1) with a ring winding (2) whose coils can be combined optionally with each other in series and/or in parallel with the aid of electronic or mechanical switches. The stator can have any number of phases and pole pairs and its rotor has one or more rectangular or trapezoidal magnets (7) per pole.
