Title:
MOTOR CONTROL DEVICE, MOTOR DRIVE SYSTEM, AND MOTOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/107189
Kind Code:
A1
Abstract:
This motor control device is provided with a plurality of power converters (601, 602) and a plurality of microcomputers (401, 402), and controls driving of a motor (80) that has a plurality of sets of windings. The microcomputers (401, 402) carry out initial inspection of components in respective circuits after actuation. The microcomputers (401, 402) prohibit driving of a 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 inspection, the microcomputers (401, 402) start driving of the motor by synchronizing the timing between said two or more circuits determined to be normal. When only one circuit is determined to be normal in the initial inspection, the microcomputers (401, 402) start driving of the motor by said one circuit determined to be normal.
