Abstract:
A rotating electric machine, especially synchronous permanent magnet machine, is provided. The machine includes a rotor with a given number of magnets distributed along the circumference and a given number of rotor pole pairs, and further comprising a stator with a given number of stator pole pairs and a given number of stator slots. The efficiency and the power of the machine are improved by making the number of stator pole pairs independent of the number of rotor pole pairs.
