    Running time of AC servo motor
    My use case involves torque loads that are fairly constant, but at times there will be peaks (almost 50% higher loads) for short bursts. Do you have data on how long your AC servo motor can run at peak power?

    ATO Responded
    The AC servo motor has a general overload capacity of 2-3 times the rated torque. And a peak torque time withstand is of about 2 minutes.
