I have just replaced an inverter driven 3ph motor and wired it the same as the old one, it runs (cogs) backwards and is noisy. The motor is 230 v 3ph, it has 6 wires, yellow, black, white, violet, blue and brown. testing with ohm meter i have 45 ohms between yellow- black, white-violet and blue- brown. so i connected as yellow- white, violet- brown, blue- black, this should give me a delta circuit, testing on volts the readings are equal between the three terminals, what is wrong???
