Synchronous Machine Using the Fourth Harmonic

摘要

The invention relates to a permanently excited synchronous machine and a method for the suppression of harmonics. The permanently excited synchronous machine (51) comprises a stator (53) and a rotor (55). Preferably, the stator (53) comprises a three-phase winding and the rotor (55) comprises permanent magnets (57). The stator (53) has thirty-nine slots (1-39) and the rotor (55) has eight magnetic poles (79). The slots of the stator (53) are wound in such a way that a first harmonic can be suppressed by means of a winding scheme and a second harmonic can be suppressed by means of magnet geometry.
