ABSTRACT:
A motor of an increased output is provided by forming a rotor, composed of a permanent magnet circumferentially divided into equal sections and alternately magnetized in different magnetic poles, in a cylindrical shape, positioning a first coil, the rotor and a second coil along the axial direction of the rotor, providing a first outer magnetic pole and a first inner magnetic pole, magnetized by the first coil, in opposed relationship, respectively, to the external and internal peripheries of the rotor, also providing a second outer magnetic pole and a second inner magnetic pole, magnetized by the second coil, in opposed relationship respectively to the external and internal peripheries of the rotor and positioning the first outer magnetic pole and the second outer magnetic pole in an axially opposed relationship with a mutual displacement by a predetermined phase angle, or forming the ends of the first and second outer magnetic poles in a tapered shape, thereby decreasing the leaking magnetic flux.
