High response, high-speed electrically driven injection equipment
DD (Direct Drive) servo motor
A pair of powerful DD servo motors (or 4 motors for screw diameter of f120 mm or larger), which we have developed originally, is employed on the injection system. These motors are characterized with an acceleration response of injection speed equivalent to that of the accumulator hydraulic servo specification, and their sudden acceleration/deceleration and feedback controls can stop and hold the screws at any desired positions, preventing burrs or shrinkage on products.
