ABSTRACT:
A pulse or stepping motor with a stator assembly and a rotor assembly has been found. The stator assembly comprises a cylindrical housing of ferromagnetic material, the first, second, third, and fourth ring shaped stators secured in said housing with some gaps between them, a pair of circular windings secured between the first and the third stators and between the second and the fourth stators respectively, the axis of said winding being identical or parallel to the axis of the pulse motor itself, each of said stators having a plurality of magnetic poles on the inner surface of the ring shaped structure, the angular duration of each magnetic pole of each stator being of uniform pitch. The rotor assembly is rotatably inserted in said stator assembly and comprises an axis, the first, second, third and fourth rotors each confronting the corresponding stators in said stator assembly, a cylindrical permanent magnet inserted between the second and third rotors so that the magnetic flux is generated in the axis direction, each rotor having a plurality of magnetic poles on the outer surface of the same, the number of magnetic poles on each rotor being the same as that on each stator, and each rotor being positioned so that the angular relationship of the magnetic poles of each rotor is staggered by 1/4 pitch of the poles.
