A permanently-excited synchronous motor ( 1 ), comprises a stator ( 3 ) and a rotor ( 5 ), the stator ( 3 ) preferably comprising a three-phase alternating current winding and the rotor ( 5 ) permanent magnets. The stator ( 3 ) has 36 grooves ( 17 ) and 36 teeth ( 19 ), whereby only every other tooth ( 19 ) is wound with a coil ( 39 ). The rotor ( 5 ) has 22 magnetic poles. The permanently-excited synchronous motor may be embodied such that the number of effective pole pairs is a prime number.
