ABSTRACT:
The synchronous motor comprises an armature having a plurality of teeth solid with a yoke and spaced apart by slots in which coils are accommodated. An inductor comprising a plurality of magnets borne by a sole is spaced from the armature by an air-grap. The motor is so dimensioned that the teeth of the armature have a constant cross-section over their entire height and the width of the slots alongside the tooth heads is substantially equal to the width of these heads to minimize the parasitic reluctant effect due to the slots. The motor may be linear or rotary.
