One Induction motor 415 volt, 16A FLA taking current 9A, 29A, 21A. Resistance is same phase tom phase IR is healthy . What cab be problem in motor? After replacing same motor with other motor ,new motor is working well without any unbalance current .
Problematic motor is new motor and after one month use showing above mentioned problem .cage rotor is used in motor . Motor is not jam and there was no significant vibration and sound in motor.

Hi Harendra,
Have you measured the phase voltages?

Could easily be a loose connection, or incorrect crimp of a lug onto the cable core.

Matthew Pilgrim sir and g. Ole Knudsen sir ,
I measured voltage at motor terminal and voltage was equal in all phases . After replacing the motor with other motor keeping same power cable ,new motor is running well .

There is no saprking or flashover in motor terminal .

Harendar , Have you checked its Rotor.

Mr. m aseem siddiqui - Rotor is not checked . But Motor was running well for almost 6 month and there was no vibration problem . Cage rotor is used in motor ,so there is less chance of rotor creak.

Have you tested it again after having it disconnected?
Did you test the individual windings resistance after disconnecting it?

If maintenance is done with motor and all 6 terminals are disconnected from the motor terminal then it is very common that the change of direction of phase winding for example the terminal on motor connector is for A1 side of the A winding and wrongly placed with A2 side, when making Y or Delta connection it will create an Amp Un-Balance but it will not allow to run for a while so if the case is like this make sure. For rotor even cage type some time because of manufacturing defect molded bar is broken and such phenomena is developed but important is Slip increased ( speed on Load reduced).
