    摘要: A device for the detection of the center of rotation of a rotating object under test comprises means for illuminating a laser beam on at least one position on the surface of the object thereby generating an interference fringe, means for subjecting the resultant reflected scattered laser beams to spectral analysis by the laser Doppler effect thereby finding the velocity of rotation of the position at which the interference fringe is formed on the surface, and means for determining the center of rotation on the basis of the velocity so found. Protection of the spectral analysis from the adverse effect of the pedestal component is accomplished by causing interference fringes to be formed at a plurality of positions on the surface of the object under test or by placing in the optical path for one of the pair of laser beams a prism capable of continuously modulating the laser frequency.

    摘要: The present invention is intended to provide a magnetic gear structure that realizes a magnetic gear that transmits a torque efficiently by reducing eddy currents generated in the interior of magnets. In order to solve the subject described above, in the magnetic gear structure, a structure in which magnets are arranged in the interior of an iron core in an inner rotor portion. Bonded magnets formed by molding, for example, NdFeB powder may be used as the magnets. Since the influence of the eddy current on the side of an outer rotor having a larger pole number is large, a structure in which the magnets are arranged in the interior only of an outer rotor portion having a larger pole number is also applicable. In addition, the magnets to be embedded may be divided into a plurality of pieces. The finer the division of the magnets, the less eddy currents are generated, so that a method of further fining down and assembling the same is also effective. Further reduction of the eddy currents is possible by laminating the plate-shaped magnets having a thickness equivalent to an electromagnetic steel plate in the axial direction.

    摘要: It is an object of the present invention to make it possible to easily wind a stator winding, enhance an occupied ratio in a stator core, reduce a winding resistance because there is no coil end, and change a field magnetic flux in accordance with a use.Stator pawl magnetic poles of a stator core extend from both sides in an axial direction alternately at locations opposed to a rotor to form a plurality of magnetic poles. With this stator core, it is only necessary to annularly wind a stator winding. Therefore, it is possible to enhance operability and an occupied ratio, and since there is no coil end, it is possible to reduce winding resistance. Since the rotor is a Randall type rotor having a field winding and a rotor pawl magnetic pole, it is possible to change the field magnetic flux in accordance with a use.
