PRESSE MIT EINEM SERVOANTRIEBSSYSTEM |
摘要 |
<p>A servo drive system of a press machine has a pair of servo motors 30a and 30b which can generate necessary ram pressure by compositing and using a torque based on the same speed-torque characteristics. The servo motors 30a and 30b are symmetric with each other in a mirror image manner. The servo motors 30a and 30b are opposed to each other at opposite ends of an operation shaft 20 which vertically moves a ram 22. The servo motors 30a and 30b are integrally operated, thereby directly driving the operation shaft 20. <IMAGE></p> |
