The hollow rotating platform is a revolutionary product. For a variety of rotating motion occasions. Can replace DD MOTOR and CAM divider. Set high efficiency, high precision, high rigidity, high cost performance in one. It is a revolutionary product in the rotating motion mechanism. Balance between the two, repeated positioning accuracy ≦5 seconds, the motor is easily prepared, the load is stable, can be matched with AC servo motor or stepper motor to do arbitrary Angle segmentation, both to meet the digital control that the divider can not achieve, positioning accuracy is comparable to DD motor. It can greatly reduce the cost and bring you unexpected results.
