Product Details 180 B Series 17-bit/23-bit Absolute Value Five-pair Pole Servo Motors Features: 17/23-bit absolute value photoelectric encoder, with high-end and high responsiveness characteristics. Speed: High-speed performance is good. Generally, the rated speed can reach 3000 rpm, and the maximum speed can reach 6000 rpm. Adaptability: Strong overload resistant ability, able to bear three times the rated torque load. Particularly suitable for occasions with load fluctuations and requiring quick starts. Stability: Runs smoothly at low speeds, without the step-like running phenomenon similar to stepper motors. Suitable for occasions with high speed response requirements. Opportunity: The dynamic response time for acceleration and deceleration of the motor is short, generally within a few dozen milliseconds. Comfort: Heat generation and noise are significantly reduced.
