Abstract
A three-phase dynamoelectrical permanently excited synchronous machine includes a stator with teeth which point to a rotor, wherein twelve slots are formed between the teeth. The slots have coil sides of coils of a winding system in such a manner that two coil sides of different coils are situated in each slot. The rotor has a cylindrical support structure which is provided with permanent magnets defined by an inner radius which corresponds to a radius of the support structure, and by an outer radius which is smaller than their inner radius. The permanent magnets are formed with ten magnet poles when viewed in a circumferential direction.
