A miniature synchronous motor is made by forming a toothed stator in two parts. One part is moulded into a coil former by injection moulding, the moulding carrying a rotor bearing seating. The other part is located on and fastened to the first part unit by an insulating shell which also carries a rotor bearing seating. The rotor is multipolar and permanently magnetized.
