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