Abstract
An injection molding machine includes a motor; a driver circuit; a rectifying part; a capacitor provided between the driver circuit and the rectifying part; a bridge circuit that converts direct electric power between the driver circuit and the rectifying part into alternating electric power; a harmonics component reducing part connected to an alternating side of the bridge circuit; and a regenerative line connected to the rectifying part in parallel, wherein the bridge circuit and the harmonics component reducing part are provided in the regenerative line, and plural switching elements of the bridge circuit are turned on or off such that electric power of the motor is regenerated when a voltage of the capacitor is greater than or equal to a predetermined value, and all the switching elements are turned off when the voltage of the capacitor is less than the predetermined value.
