PROBLEM TO BE SOLVED: To provide an injection molding machine that can prevent overcurrent from flowing, in other electric power lines in the disconnection of the electric power line.SOLUTION: An injection molding machine includes: a motor; a drive part for driving the motor; a conversion part for converting regenerative electric power supplied via the driving part into AC electric power; a breakage detection part for detecting a disconnection of a plurality of power lines that transmits the AC electric power; and a control part for controlling a current flowing in another power line that is not disconnected when the breakage detection part detects the disconnection of the first power line. In the injection molding machine, the control part synchronizes the current that flows in the other electric power lines to the voltage of the concerned electric power line. |
