Abstract
A permanently-excited dynamoelectric machine includes a stator and a rotor supported for rotation about an axis. The stator has a winding system, which is embedded in grooves of a material forming a magnetic return path and interacts electromagnetically with permanent magnets of the rotor via an air gap between the stator and the rotor. The permanent magnets are disposed on the rotor, with each individual permanent magnet, on a side facing towards the air gap, having a North and South pole. The rotor, viewed in the circumferential direction, has a pole coverage by the permanent magnets of 100%, i.e. that the permanent magnets viewed in the circumferential direction, are arranged substantially without gaps.
