    I would like to know how I could run the direct driver motor from LG washing machine.

    The motor type is WDC266C03R.SL:

    It has a 3-phase input. I tried to run it from variac and also triac, 230V 50Hz, with 200uF 450VAC starting capacitor connected between the one unused phase and the one of the used phases. It works but the windings get insanely hot so I have to unplug it quickly.

    So my questions is: does somebody know the parameters of this motor? - Google didn't help...
    What voltage, frequency and duty cycle should I use?

    It is a Fischer-Paykel (or copy) so requires the ECM (3ph) electronic drive suitable for powering it.
    I have not come across a controller yet, there are quite a few using them for wind generators.

    A BLDC motor driver would work. I use Fischer and Paykel motors as a tester for the BLDC controllers I make. They run ok on 24VDC, but not with a lot of torque.
    The smaller connector will be for Hall sensors to detect the rotor position, and the larger connector is the motor coils.
    A 3 phase bridge H (if you can call a 3 phase one an "H") circuit is needed, and a processor to sense the position and drive the bridge. The one I use is a dsPIC30F4011 and there are some app notes for it around.
