An injection molding machine (1, 2) includes a motor (50), a driving part (40) configured to drive the motor, a conversion part (20) configured to convert regenerated electric power supplied via the driving part into alternating current electric power, and a breakage detection part (66, 67) configured to detect a breakage of an electric power line (25) transmitting the alternating current electric power based on the result of a d-q transformation of an alternating electric current flowing through the electric power line. |
