ABSTRACT:
A stator of an electric motor with four poles which are all parallel to each other and arranged in mutually opposite pairs around the rotor cavity. Each pole has a pole shoe which is inclined toward the inside of the stator so as to form, in practice, the rotor cavity. The mutually closer ends of the four pole shoes are mutually rigidly coupled by two thin bridges which are parallel to the axes of the poles and by two similar thin bridges arranged transversely to the axes of the poles. The poles of each pairs of parallel poles are also mutually rigidly coupled by transverse cores which can be inserted in them and removed from them, so as to allow the insertion of the bobbins of the winding coils on the cores before the cores are fitted on the respective poles.
