my existing 3 phase motor,15kw, 220 volts,six lead terminals labeled as Z,X,Y,U,V, and W respectively. i want to use it, though i know its rating will drop by 30% in terms of kw. my power source is single phase,220 volts. i want to know how to connect its lead terminals or will i need capacitors as starter and whats the ampacity of the capacitor.
that doesnt seem like it will work, regardless of the capacitors. a polyphase motor is wired so that the phase difference causes a rotating magnetic field to drive the rotor. edit: apparently some 3-phase motors are wound so that you can convert them to single phase 220v applications. these are not typical, however and the enclosure for the terminals would show the correct wiring configuration for what you want if the motor is wound properly.
I don't know where you get your 30% reduction figure from. You can use a capacitor to get the thing to run with little or no load, but 70% of rated power?...............I very much doubt it. Also 15kw is a massive power from single phase. Along with the terrible power factor you will have, expect far more current than a standard 13A outlet is going to give you.
I don't think it's possible..
