A synchronous motor with permanent magnets includes a rotor (110) provided with permanent magnets, and a winding (120) formed by overlapping coils located inside a slotless stator (100). The winding coils (120) are regularly distributed all around the 360° of the inside surface of the stator (100) and the ends of the coils are designed such that the winding has the same thickness throughout and the ends of the winding are at least partially inside the slotless stator (100).
