I'm facing a problem in diagnosing the main reason behind the 7kW motor's current imbalance. It's line current is 14.2A 13A 10.6A. The voltages are balanced. I've rotated the phase, and checked that the currents move with the conductor change. This confirms that the problem is with the motor. The resistance of the windings of the motor is also balanced, i.e 2.6 ohms for all windings.
I just have clamp meter, multimeter, & contact tachometer as my analysis instruments.
Thanks
