ISMT series precision direct drive rotary (DDR servo motor) products are high precision direct drive devices developed by Inovance Technology. This series of motors can directly drive the load for precise positioning without the need for a reduction gear. It has extremely high system accuracy and rigidity. The hollow shaft structure allows wiring and air pipes to pass through it, thus saving space. With the 620 series high-performance servo driver, the repeat positioning accuracy can reach ±3 arc seconds and the operation is quiet and stable, which can realize fast and accurate position control, speed control and torque control. The first choice for industrial applications.
