    I have found some 2kw 48v DC motors that look pretty useful

    they are brushless

    will the SMC3 be able to control a brushles motor ?

    will a special motor driver be needed ?

    SMC3 doesn't have a brushless mode but if a brushless motor driver exists that accepts pww and direction or inverted pww signals then it might work with mode 1 or 2.

    ok - probably easier to stick with a DC motor and a h-bridge

    has anyone used the SMC3 with ac motors - I assume it needs an inverter with pwm and direction

    Agree with first paragraph.

    What do you mean by an inverter? Unless using an ac servo motor with its own controller most use a vfd usually requiring 10 volts which an arduino is incapable of on its own.

    If you want the brushless route, take a look at my thread: https://www.xsimulator.net/community/threads/flypt-6dof-brushless-diy-actuators.10799/
    The BLDC-8015A can handle 24V to 50V and rated 15A to a 45A peak
    But there are other alternatives.
    Can you give a link to those motors?
