Abstract
A single phase induction motor of a capacitor run type comprising: a stator including a stator core having a circle aperture and a plurality of slots formed extending in the axial direction of the aperture whereby a plurality of teeth are formed therebetween, two main winding coils wound around two teeth to form two main excited poles of the same polarity at the diametrical positions of the stator core, the two main excited poles of one polarity causing two main image poles of the opposite polarity at the positions between the excited poles, two auxiliary winding coils wound around two teeth, shifted by one tooth from those of the main winding coils, to form two auxiliary excited poles of the same polarity at the diametrical directions of the stator core, the two auxiliary excited poles of one polarity causing at least two auxiliary image poles of the opposite polarity at the positions between the auxiliary excited poles, whereby two pairs of main and auxiliary excited and image poles are formed sequentially in the circumferential direction of the aperture, whereby a rotating magnetic field is generated through interaction of the main and auxiliary magnetic fields by the pairs of poles; a capacitor connected in series with the auxiliary winding coils for shifting the phase of the current flowing therethrough; a rotor mounted to rotate within said aperture of the stator core; a bracket having bearings for rotatably supporting the rotor within the aperture of said stator core, the bracket being mounted to the positions at the end surfaces of the stator core where the teeth are not wound of winding coils and the image magnetic coils are formed; and bolts and nuts for fixing the bracket to said stator core at said positions where teeth are not wound of coils.
