ABSTRACT:
A small electric motor including one or more field coils which cooperate with a long, thin cylindrical rotor having only a single pair of nonsalient rotor poles. A stator pole piece assembly is in magnetic flux relationship with the rotor and is provided with salient stator poles which each subtend an angle of at least about one hundred and twenty degrees with respect to the axis of rotation of the rotor. In some embodiments the stator poles are arranged in sets which cooperate with different axial portions of the rotor.
