Provided is an injection molding machine (2) that can reduce heat generation of a control unit (70) of a three-phase AC motor. An inj ection molding machine (2) includes a three-phase AC motor configured to drive a movable part; and a control unit (70) configured to control the three-phase AC motor. The control unit (70) controls the three-phase AC motor, using a voltage command value of two-phase modulation, when predetermined conditions are satisfied, and the predetermined conditions include at least that the speed of the movable part is equal to or less than a predetermined value. |
