摘要： A single-phase motor comprising a rotor magnet, a stator core having salient poles, and a coil wound around the stator core, a rising portion and a falling portion of a voltage applied to the coil have different inclinations, wherein the salient pole is separated into three angle portions, a radius of an outer shape of the salient pole is reduced little by little with respect to a rotating direction of the rotor in a first angle portion with respect to the rotating direction of the rotor, is increased little by little with respect to the rotating direction of the rotor in a second angle portion with respect to the rotating direction of the rotor, and is increased little by little with respect to the rotating direction of the rotor in a third angle portion with respect to the rotating direction of the rotor, and a rate of increase of the third angle portion is gentler than that of the second angle portion. Accordingly, it is possible to provide a single-phase motor having a small torque pulsation, a low noise and a low vibration.

摘要： In order to reduce undesired sound caused by circular ring oscillation in the diametric direction of the stator by an electromagnetic force, electromagnetic force drift memory stores a drift information of the electromagnetic force causing the circular ring oscillation of the stator. This electromagnetic force drift information is read out according to the position information &thgr; and is supplied to a correction coefficient generating circuitry. Correction coefficient generating circuitry corrects the amplitude component of the activation current wave from by forming correction coefficient &bgr; (t) of the activation current so as to cancel the electromagnetic force harmonic component in the diametric direction which component is the component of the circular ring oscillation of the stator.

摘要： This rotating electrical machine includes a stator, a rotor having a plurality of convex portions on its surface that opposes the stator and extending along its direction of rotation, a magnet, and a frame made from magnetic material. The number of poles of the stator is the same as the number of magnetic convex poles of the rotor. The rotor is made from a plurality of plates of magnetic material, superimposed and skewed along the axial direction. A magnetic circuit is set up in the frame so that the magnetic flux of the magnet flows therein from the central portion of the rotor. And the magnet is a permanent magnet shaped as a cylinder, is single-pole magnetized along the radial direction, and is provided between the outer circumferential surface of the stator in the circumferential direction and the inner circumferential surface of the frame in the circumferential direction.
