Abstract
An injection molding machine according to the invention includes a motor, a driver circuit that drives the motor; and a rectifying part that supplies electric power to the driver circuit. A regenerative line for regenerative electric power of the motor is connected to the rectifying part in parallel. A converting part and a harmonics component reducing part are provided in the regenerative line. The converting part converts direct electric power between the driver circuit and the rectifying part into alternating electric power which is input to the harmonics component reducing part.
