ABSTRACT:
A method is disclosed for manufacturing a synchronous electric motor which includes at least one flat annular rotor part which is magnetized so as to present at least one series of magnetic poles arranged along a flat annular zone of the rotor part. The rotor part is fixed by at least one rotor-supporting part on a shaft of the motor. The motor shaft is mounted for rotation with respect to at least one stator assembly which includes at least two stator parts. The stator parts include pole parts arranged so as to form, in their assembly, an air-gap in which are disposed the magnetic poles of the rotor part. At least one electric control coil is coupled with one or more pole parts.
