MOTOR CONTROL SYSTEM

In a motor control system, a plurality of motor control devices for controlling motors and a controller are connected to each other via a communication line. The controller generates a communication signal including an operation command, and transmits the communication signal to the respective motor control devices in a predetermined communication cycle. The plurality of motor control devices includes two motor control devices in a first group and a motor control device in a second group. Each of the motor control devices in the first group includes a data transceiver, a motor controller, a corrector, and a synchronous timing generator. 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 for controlling the motor. 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.
