* The three switches are in a single package and are therefore always switched together. * The coils and resistors may not be the most accurate representation of a three phase motor, but I think its ok in this context. Notes: I'm not a power engineer, so I can/will not guarantee the authenticity of this schematic, but it's my best guess. 380 V are no joke, so take care :) My other designs: Colpitts Oscillators http://everycircuit.com/circuit/6472095956729856 Binary LC Filter Bank Oscillator http://everycircuit.com/circuit/5849640909144064 LC Filter Bank Oscillator http://everycircuit.com/circuit/6141020952854528 RF Up and Down Mixing http://everycircuit.com/circuit/6321309163454464 DC Motor Rev.

Even you are not a "power" engineer, you should know/learn the difference about 230Vpeak and rms. Check your AC powersources which are wrong in voltage!

You are right, i forgot! Sorry about that

Hope the connections were helpful though

Haven't checked your wiring, anyway the currents after changing all switches seems to make sense, so the wiring. Check this relais version I made http://everycircuit.com/circuit/5727350734979072

Yeah, saw it yesterday after I purplished this one. Good idea with the relays.

Btw, this was a response to wanimicheals comment in http://everycircuit.com/circuit/5502940846751744. Didn't see Richs link until later. Otherwise I wouldn't have made one myself :)
