three-phase current imbalance reasons(1) the three-phase power supply voltage unbalance. (2) a motor phase winding part of the coil assembly or wrong. (3) the motor windings are short-circuit. If a short circuit, the motor not only fever, accompanied by a special noise. (4) motor stator winding open circuit. Most of the user the power problems, specific detection method usingphase inversion. Motor, three-phase current unbalance。 |
