text: <s>[INST] AC driver 3.7KW can use for motor 4KW I have an AC drive 3.7KW. Can it use for motor 4kW ? [/INST] RiverVN, normally this is not possible, because the motor is bigger size than drive... just check the FLA current the motor needs, and verify if the drive could supply it. I suggest to go with 4 Kw drive, to better manage intermittent overload, and also start-up current. Hope this helps.... - fuzzy logic \\n </s>
