高可靠性 内部抑制过滤功能

负载惯性自检测


product description:

The whole series adopts resolver feedback, which can realize torque control, speed control and closed-loop control of the motor shaft position. In addition, it can also accept photoelectric encoder feedback and grating scale feedback to achieve the final full closed-loop control of the control target.

1. Precision control (speed accuracy 0.1%, torque fluctuation less than 1%);

2. More energy-saving (10-15% more energy-saving than ordinary servo);

3. Strong explosive force (15ms acceleration at no load, 26ms acceleration at full load).
