Features: 17-bit or 23-bit absolute value photoelectric encoder, with high quality and high responsiveness; Speed: Excellent high-speed performance, rated speed can generally 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 quick start; Stability: Smooth operation at low speed, no step operation phenomenon similar to stepper motors will occur during low-speed operation. Suitable for occasions with high-speed response requirements; Opportunity: The dynamic response time of motor acceleration and deceleration is short, generally in tens of milliseconds; Comfort: Heat and noise are significantly reduced.
