Patent number: 11984751Abstract: A discharge circuit for a power supply circuit for a motor is configured to discharge a capacitor provided in the power supply circuit. The discharge circuit includes a first voltage detector detecting a voltage inputted to a primary side of the power supply circuit, a second voltage detector detecting a voltage on the secondary side, and a discharge resistance provided in parallel with the power supply circuit on the secondary side of the power supply circuit. A power supply control means performs discharge control when a voltage detected by the second voltage detector exceeds a regenerative determination value and, in a case that a voltage on the primary side detected by the first voltage detector becomes lower than a power failure determination value, the power supply control means performs the discharge control after a lapse of a time period required for a stop operation of the industrial robot.Type: GrantFiled: December 2, 2021Date of Patent: May 14, 2024Assignee: NIDEC SANKYO CORPORATIONInventor: Hiroaki Nagata

Patent number: 11791093Abstract: A sintered magnet body (RaT1bMcBd) coated with a powder mixture of an intermetallic compound (R1iM1j, R1xT2yM1z, R1iM1jHk), alloy (M1dM2e) or metal (M1) powder and a rare earth (R2) oxide is diffusion treated. The R2 oxide is partially reduced during the diffusion treatment, so a significant amount of R2 can be introduced near interfaces of primary phase grains within the magnet through the passages in the form of grain boundaries. The coercive force is increased while minimizing a decline of remanence.Type: GrantFiled: February 26, 2020Date of Patent: October 17, 2023Assignee: SHIN-ETSU CHEMICAL CO., LTD.Inventors: Hiroaki Nagata, Tadao Nomura, Takehisa Minowa

Publication number: 20220410389Abstract: A robot system includes a manipulator having a plurality of axes and driven by a motor provided for each axis, a robot controller, an encoder attached to the motor for each axis, an encoder wiring line connecting the encoder with the robot controller, a storage part in the manipulator which stores mechanical parameters including identification information for discriminating the encoder for each axis, and a control part in the robot controller which reads out the mechanical parameters from the storage part and communicates with the encoder through the encoder wiring line. The control part discriminates whether the identification information read out from the encoder and the identification information included in the mechanical parameters are coincided with each other or not for each axis and, when both the identification informations are not coincided with each other, the control part determines that erroneous wiring exists in the encoder wiring line.Type: ApplicationFiled: June 14, 2022Publication date: December 29, 2022Inventor: Hiroaki NAGATA
