The microcomputers perform initial check of components in respective circuits after activation. The microcomputers prohibit driving of the motor by a circuit determined to be abnormal during the initial inspection. When two or more circuits are determined to be normal in the initial check, the microcomputers start driving of the motor by synchronizing the timing between the two or more circuits determined to be normal. When only one circuit is determined to be normal in the initial check, the microcomputers start driving of the motor by the one circuit determined to be normal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Motor control device, motor drive system and motor control method","description":"A motor control device is provided with a plurality of power converters and a plurality of microcomputers, and controls driving of a motor that has a plurality of sets of windings.
