Patent number: 11161255Abstract: Provided is a robot equipped with two joint parts attached to an end of an arm in a coupled state. For example, in a joint part of a robot, a motor and a reduction gear are housed in a case, and an output-side member having a flange is fixed to the output shaft of the reduction gear. An opening that opens in the direction orthogonal to the axial direction of the output shaft of the reduction gear is formed in the case. A planar attachment face orthogonal to the opening direction of the opening is formed in the opening. The robot is provided with a plurality of biaxial joint units comprising two joint parts. In the robot, the attachment face of the case of one joint part constituting a biaxial joint unit is fixed to the flange of the other joint part either directly or via a coupling member.Type: GrantFiled: March 9, 2017Date of Patent: November 2, 2021Assignee: NIDEC CORPORATIONInventors: Yuu Ayuzawa, Haruhiro Tsuneta, Hideyuki Odagiri, Hirokazu Watanabe

Patent number: 10666171Abstract: A motor system includes a motor, and a multi-turn absolute encoder that detects a rotation number and an absolute angular position of a rotation shaft of the motor. The multi-turn absolute encoder includes: an absolute angular position detection device that detects the absolute angular position within one rotation period of the rotation shaft; and a storage element that stores the rotation number of the motor. Even if the driving of the multi-turn absolute encoder is stopped while the motor is stopped, the multi-turn absolute encoder detects the multi-turn position of the rotation shaft after startup. Further, the motor has a brake mechanism including: a gear-type brake wheel that rotates integrally with the rotation shaft; an engagement member capable of engaging with the teeth of the gear-type brake wheel; and an actuator which causes the teeth and the engagement member to engage with each other during braking.Type: GrantFiled: March 9, 2017Date of Patent: May 26, 2020Assignee: NIDEC CORPORATIONInventors: Hideyuki Odagiri, Haruhiro Tsuneta, Yuu Ayuzawa, Shunya Yazawa

Patent number: 10345827Abstract: A motor control device may include a position command output means, a first subtraction means that calculates and outputs a position deviation, a position control means, a second subtraction means that calculates and outputs a position deviation, a speed control means that outputs a torque command, a limiter limits the level of the torque command, a motor drive means, and a voltage fluctuation detection means. When the voltage fluctuation detection means detects that the voltage of said power source has dropped below a predetermined reference level, either the position command output means varies the position command so as to reduce the rotational speed of the motor and/or said position control means limits said speed command to be output.Type: GrantFiled: August 6, 2011Date of Patent: July 9, 2019Assignee: NIDEC SANKYO CORPORATIONInventors: Jun Otsuji, Akihiro Ito, Hirokazu Watanabe, Hideyuki Odagiri
