Zusammenfassung: | A motor driving apparatus includes a first motor group including a number N of individual servo motors, a second motor group including a number N of individual second servo motors driven synchronously with the servo motors, and an inverter control unit. The inverter control unit controls a first switching total value and a second switching total value to be reversed in positive/negative sign. The first switching total value is obtained by subtracting the number of semiconductor switching devices opened in circuit on low potential side from the number of semiconductor switching devices opened in circuit on first high potential side, corresponding to the first motor group. The second switching total value is obtained by subtracting the number of semiconductor switching devices opened in circuit on high potential side from the number of second switching elements opened in circuit on low potential side, corresponding to the second motor group. |
