Features: 17-bit 23-bit absolute value photoelectric encoder, with high-end and high responsiveness; Speed: Good high-speed performance, generally rated speed can reach 3000 rpm, maximum speed can reach 6000 rpm; Adaptability: Strong overload resistance, can withstand load three times the rated torque, especially suitable for occasions with instantaneous load fluctuations and requiring fast start; Stability: Smooth low-speed operation, no stepping operation phenomenon similar to stepper motors will occur during low-speed operation. Suitable for occasions with high-speed response requirements; Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds; Comfort: Heat and noise are significantly reduced.
