| Summary: | This paper evaluates the performance of an inverter-fed nine-phase squirrel cage induction motor (SCIM) under faulty conditions. The induction motor’s stator core of the conventional National Electrical Manufacturers Association (NEMA) frame size of 90L has been rewound to accommodate coils that form the nine-phase windings. The prototyped nine-phase SCIM drive has been tested for transient and steady-state capabilities for well-conditioned and defective functioning. The open-phase-winding faults are caused by fuses opening during an imposed short circuit. The experimental results evidenced that the nine-phase induction motor drive can operate under faulty conditions while minimizing the gravity of defective functioning. This premise has positioned the nine-phase SCIM drive as a strong candidate in applications where fault tolerance is a must, and the motor may be required to continue operating temporarily under faulty conditions until maintenance is in effect. |
