    Operating temperature of 3.7kW AC servo motor
    I need to run a 3.7kW AC servo motor at a temperature of minus 40°C. Can it run at this temperature?

    The ambient temperature of our servo motor should be in the range of (-20C~+40C). If running outside of this working range, the motor will be damaged.
