  • Patent number: 11003154
    Abstract: A motor control system includes motor control devices and a controller. The controller generates and transmits a communication signal including an operation command to the respective motor control devices. The motor control devices include two motor control devices in a first group, each of which includes a data transceiver, a motor controller, a corrector, and a synchronous timing generator, and a motor control device in a second group. The data transceiver receives an operation command issued to the motor control device, and receives operation information in the motor control device in the second group. Based on the operation command, the motor controller generates a torque command signal. The corrector generates a torque correction signal based on the operation information, and corrects the torque command signal. The synchronous timing generator generates a timing signal that matches pieces of process timing of the motor controllers in the first group with each other.
