To provide a motor control system, a motor control device, and a motor control method that can reduce the processing load on a host control device.SOLUTION: A motor control system 1 includes a host control device 3 that outputs control commands, multiple motor control devices 5A to 5D that control multiple motors 7A to 7D on the basis of the control commands and drive mechanical elements 15A to 15D, and an external sensor 17 for outputting information on the mechanical element 15D to the motor control device 5D. Each of the multiple motor control devices 5A to 5D includes an information sharing unit 23 for sharing information on the mechanical element 15D with each other through data communication among the multiple motor control devices 5A to 5D, a command conversion unit 25 for converting the shared information on the mechanical element 15D into a control command for autonomous operation by the motor control devices 5A to 5D themselves, and a motor control unit 27 for controlling a motor 7 on the basis of the converted control command.SELECTED DRAWING: Figure 2 【課題】上位制御装置の処理負荷を軽減することが可能なモータ制御システム、モータ制御装置、及びモータ制御方法を提供する。【解決手段】モータ制御システム１は、制御指令を出力する上位制御装置３と、制御指令に基づいて複数のモータ７Ａ～７Ｄを制御して機構要素１５Ａ～１５Ｄを駆動する複数のモータ制御装置５Ａ～５Ｄと、モータ制御装置５Ｄに機構要素１５Ｄに関わる情報を出力する外部センサ１７と、を有し、複数のモータ制御装置５Ａ～５Ｄの各々は、機構要素１５Ｄに関わる情報を複数のモータ制御装置５Ａ～５Ｄ間のデータ通信を介して互いに共有する情報共有部２３と、共有した機構要素１５Ｄに関わる情報をモータ制御装置５Ａ～５Ｄ自身による自立運転用の制御指令に変換する指令変換部２５と、変換された制御指令に基づいてモータ７を制御するモータ制御部２７と、を有する。【選択図】図２
