摘要： An electric injection molding machine comprises a barrel which holds a screw therein, a voice coil type linear motor which moves the screw in the axial direction thereof. The linear motor has a coil, a yoke extending along the coil, and a magnet movable relatively to the coil in the axial direction thereof. The injection molding machine comprises a coolant passage in the yoke and a cooling device for cooling the coil. Temperature related to the coil or a coolant is detected, and the coolant is control in accordance with the detected temperature.
