Patent number: 11658601Abstract: A motor control device includes a power converter that supplies a three-phase voltage to two motors being connected in parallel, a three-phase power line that connects between one of the two motors and the power converter, a branch three-phase power line that connects between the other of the two motors and the power converter, a switching device having two switches that are provided on the branch three-phase power line, a current detection device that detects three-phase currents flowing in the two motors, and a controller. The controller performs a failure determination of the switching device by identifying a phase of a power line in which no current flows in the three-phase power line and the branch three-phase power line, and, when a failure is detected in one of the two switches in the failure determination, controls to change a state of the other switch, which operates normally, to coincide with a state of the failed switch.Type: GrantFiled: April 23, 2019Date of Patent: May 23, 2023Assignee: Mitsubishi Electric CorporationInventors: Toshiki Asai, Akihiro Tsumura, Yasuhiko Wada, Junji Morimoto, Shigeo Takata

Patent number: 11424698Abstract: A motor control device includes: an inverter circuit configured to convert a direct-current voltage into an alternating-current voltage, and to supply the alternating-current voltage to a plurality of motors connected in parallel; current detectors configured to detect motor currents flowing through the respective motors; a relay provided between at least one of the plurality of motors and the inverter circuit; and a controller configured to change the number of motors to be driven. When one of two or more motors under driving is stopped, the controller lowers a current instruction value to the two or more motors under driving. When a monitor current that is the motor current detected by the current detector of the motor connected to the relay is decreased, the controller switches the relay from an on state to an off state.Type: GrantFiled: January 16, 2019Date of Patent: August 23, 2022Assignee: Mitsubishi Electric CorporationInventors: Akihiro Tsumura, Yuichi Shimizu, Yasuhiko Wada, Junji Morimoto
