Study of Unbalanced Voltage on Rotor Classes of Induction Motor according to the NEMA standard

摘要

Faults of the electrical system, for example unbalanced voltage condition and inconsistent frequency, are frequently occurred, which reduces quality of the electrical system and affects efficiency of electrical appliances. This research aims to study unbalanced voltage on rotor classes of induction motors according to the NEMA standard. Several tool methods, for example FEM, are selected to illustrate the effect of unbalanced voltage condition on the induction motor.
