    1. Accuracy: ATO AC servo motors realize closed-loop control of position, speed and torque, overcome the problem of stepper motor out-of-step.
    2. Speed: Good high-speed performance, rated speed can reach 1000-3000 rpm.
    3. Adaptability: ATO heavy duty servo motors with strong anti-overload capability, able to withstand a load three times the rated torque, especially suitable for occasions with instant load fluctuations and requiring quick start.
    4. Stable: Our AC brushless servo motors have smooth low-speed operation, no stepping phenomenon similar to stepper motor will occur when running at low speed, suitable for occasions occasions requiring fast response.
    5. Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds.
    6. Safety: ATO AC servo motor protection grade is IP65, which meets the waterproof and dustproof requirements.

    Tips: Oil and water resistant protection for servo motor

    1. Servo motor can be used in those places where the water or oil drop may invade, but it cannot fully resist the water or oil invasion. Therefore, servo motor should not be placed or used in water or oily environment.
    2. If the servo motor is connected with a reduction gear, it should be added oil seal before use to avoid oil in reduction gear entering servo motor.
    3. Do not soak the servo motor cable into oil or water.

    I'm still working on this servo motor
    I bought and bought two servo motors. They can be used, but they can't be compared with the big ones. The price is real, debugging. It took a little more effort, it took a long time to adjust, and it can be used, but it was not adjusted to the ideal state, maybe my method is wrong, I will try it next time.
