Well, first, is there a neutral conductor?

Hi

there are no. of reasons for unbalanced current for motor

1) mechanical unbalanced rotor

2) Unbalanced electrical load if motor is supposed to drive induction generator

3) unbalancing in stator winding

4) unbalanced magnetic circuit

5) improper shorting of rotor circuit

some other reasons may also lead to unbalancing of current

Thanks & regards
