    Features

    • Accuracy: ATO AC servo motors realize closed-loop control of position, speed and torque, overcome the problem of stepper motor out-of-step.
    • Speed: Good high-speed performance, rated speed can reach 1000-3000 rpm.
    • 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.
    • 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.
    • Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds.
    • Safety: ATO AC servo motor protection grade is IP65, which meets the waterproof and dustproof requirements.

    3 tips for replacing stepper motor with servo motor

    1. To ensure that there is not too big change in control system, it is suggested to choose digital servo system, which can still use the original pulse control method.
    2. As the overload capacity of servo motor is strong, 1/3 of original stepper motor rated output torque can be as reference to determine the servo motor rated torque.
    3. Since the rated speed of servo motor is much higher than stepper motor, it is better to add a deceleration equipment, so as to make servo motor run at rated speed. To reduce the cost, it is also feasible to choose the motor with smaller power.
