OK , there is the exact situation:
On a compressor we have a 150 HP rebuilt motor, 575V , 6 wires (3 windings) , control by a set of 3 (new)contactors for proper star-delta running.
Windings are equals in resistance ( 0,0310 0,0312 0,0309 ohm) Voltages delta is acceptable (577 581 587)
Lines...
Someone have an idea of the impact of having one of the 3 motor windings reversed (exemple: if wires U1-U2 and V1-V2 are connect normaly but W1-W2 are swapped.
Will it start, and if yes, what will append to the phases currents of the motor ? Two coils will be opposed to the reversed one? Will...
