  • Patent number: 10892695
    Abstract: A low-frequency torque controller 9 outputs a low-frequency torque controller output ?dc* based on a torque command value ?* and a torque detection value ?det, and a vibrational torque controller 11 outputs a vibrational torque command value ?pd* based on the torque command value ?*, the torque detection value ?det, and a rotational phase detection value ?. Meanwhile, in a high-frequency resonance suppression controller, an inverter torque command value ?inv* is outputted based on the torque detection value ?det and a corrected torque command value ?r* obtained by adding the low-frequency torque controller output ?dc* to the vibrational torque command value ?pd*. The invention thus provides shaft torque vibrational control of a motor drive system wherein engine vibrational torque command values including distortion components are tracked while entirely removing the influence of resonance, non-periodic disturbances, and periodic disturbances.

  • Publication number: 20200408990
    Abstract: In an optical switch array on which optical switches that require individual electric wires are integrated, the present invention provides an optical switch array and a multi-cast switch in which the electric wires are shortened by optimizing the arrangement of the optical circuit portion. In the optical switch array in which three arrays of 1×4 switch circuits are disposed in parallel, the position where each optical switch is disposed is sequentially shifted by Dy in the y axis direction. That is, in the case where an adjacent 1×4 optical switch circuit exists on both sides, the 1×4 optical switch located there between is located at the center of the two 1×4 optical switch circuits, which are adjacent in the y axis direction.

    Abstract: Provided is a method for producing a sintered body that forms a rare-earth permanent magnet, has a single sintered structure and an arbitrary shape, and has easy magnetization axis orientations of different directions applied to the magnet material particles in a plurality of arbitrary regions. This method forms a three-dimensional first molded article from a composite material formed by mixing a resin material and magnet material particles containing a rare-earth substance. The first molded article is then subjected to a deforming force and a second molded article is formed in which the orientation direction of the easy magnetization axis of the magnet material particles in at least the one section of the horizontal cross-section is changed to a direction which differs from the orientation direction of the first molded article. The second molded article is heated to a sintering temperature and kept at the temperature for a period of time.
