ABSTRACT:
The motor comprises a rotor, first and second stators surrounding the rotor and a common exciting coil for the stators. The rotor is provided with a plurality of spaced pole pairs of alternate polarities of an odd number equal to or larger than 5. The first and second stators are respectively provided with semicircular portions which face each other and the centers of these semicircular portions are displaced from the axis of rotation of the rotor such that the semicircular portions will be point symmetrical with respect to the axis of rotation. Main pole pieces are provided for respective semicircular portions at the adjacent portions thereof and interpole pieces are located adjacent the main pole pieces which are located closest to the rotor. Notches are formed between adjacent main and interpole pieces.
